Landscape Drains and Area Drains Benefit from Hydro Jetting

The primary thing to keep in my when you are trying to clear problem area drains or landscape drains is that the culprit is usually a combination of three things in varying amounts.

The first is usually dirt.  The drains usually occupy a low spot, if they were installed properly, and if the area around the drain is not protected or stabilized somehow by regulating the size of the material around the drain, you always end up with that material going into the drain, multiply that by10 - 15 years or more and you get a serious accumulation.

The second item is usually roots.  Area or landscape drains are notorious for being installed at a lower  quality standard.  The majority of pipe joints we encounter with regard to landscape drains are not glued.  The fact that they are simply press fitted together allows the joints to leak as they carry water to the outflow.  That leak over time brings roots into the line through the joint, they grow and expand and many times the roots will deform the pipe.  If  the pipe has substantial dirt in it as well, now you have a mass of dirt with roots combined.  This combination over years and years of accumulation, makes it pretty close to impossible to remove with a typical plumbers cable machine. The machine typically buries the cable into the dirt and many times it becomes stuck requiring a dig to get the cable out.  If that happens to be under concrete, it's going to be expensive.

"You can not cable dirt."  It just doesn't work.  

Imagine using an electric drill, put any bit on it that you please,  and start drilling into a 5 gallon bucket full of dirt.  What do you think is going to happen?  Nothing. Your going to move a little bit of dirt around but your certainly not going to remove the problem dirt.
Now, hit that same bucket of dirt with a firehose and what do you think is going to happen. Yes your right, no more dirt.  The volume and pressure of the water will put the dirt into suspension in the water and flow it out of the bucket.  Combine that with a rotating nozzle to cut roots and you begin to see the advantage hydro jetting has over running a cable.

The last item I would call "debris" and it usually ends up being chunks of something. I attached a couple of photographs to give you a "for instance."

The first is a very large amount of medium pebble rock that went into a customers landscape drains from around a koi pond.  Some of it is visible here but we probably pulled out 15 to 20 lbs of pebble rock that had mixed in with dirt in a low spot in the line run.  That could never have been removed with a cable machine.

Note the large and small chunks of rocklike material removed with Hydro Jetting.


Close up of the hardened grout, note the half pipe shape clearly visible in the left rear piece.


With this type of material, the hydro jetting with high pressure water actually gets between the pipe wall and the grout and breaks it free to move.  The water flows it out of the pipe. You could never remove this material with a cable machine.

Now let's be honest, there is no magic cure.  Landscape drains are a very difficult type of problem because there are so many variables and landscape lines are generally not installed to code.  For that same exact reason, many vendors will not service area drains. 
Regardless of how effective our hydro jetting machine is, we have seen lines that could not be cleared for a number of reasons.  Sometimes the pipes are no longer round from being crushed by a careless installer or deformed by root intrusion, or the layout and the use of  T fittings instead of a swept turn will prevent you from getting through.  Sometimes the roots are so heavy from so many years of neglect that it just isn't feasible to hydro jet and your better off replacing the line if the above ground hardscape allows it.

With all things being equal, Hydro jetting is by far a much more effective process at removing a variety of different types of debris.

Sewer Gas Smoke Test Saves the Day for Restaurant

We were called out to a family pizza restaurant in Orange County Ca by the owner of the restaurant.  They had been suffering from sewer gas issues for years and they were losing business and customers because of it. They had been working with the landlord who had been very helpful and supportive in the effort to solve the problem.  The landlord had multiple plumbers over the years each take a crack at it. Some performing smoke tests, some just recommending certain repairs.  Each one declaring the problem was fixed only to later find out that the problem persisted.  The landlord even hired a "night watchman" to sit in the property overnight for a period of months to verify if indeed the smell was still present.  He did indeed verify just that.

They even had someone come out from some official air quality management agency to take air samples.  Which is funny because typically sewer gas issues are something that comes and goes.  It's not going to be there all the time. There are many variables that will affect whether the smell is present at any one point in time.  So the odds are against you of doing any sort of a one time test and verifying the presence of sewer gas.

I'll give you a for instance. We had an architect who's office complained of sewer gas only at certain times of the year.  Without a doubt, it would go away for months at a time and then all of a sudden it was back with a vengence.  Finally the city was threatening to red tag the building so we were called in and we performed a smoke test.  We located  a cast iron sewer stack behind a toilet hidden in a wall that was split wide open for about 4 feet or more.  Well it was obvious that the hole in the pipe had been like that for years but still the smell would go away for months at a time.  The access point for the sewer gas was always there yet the gas was not always present.  That is quite common and has a lot to do with prevailing wind, doors and windows left open and so on.

Back to Orange County, multiple smoke tests had already been performed and some small leaks found and fixed.  Now the consensus was that it was the adjacent nail salon that was responsible for the leak possibly because there was a shared attic and no solid demising wall.  So we were in essence testing the nail salon looking for a source of sewer gas.  We blew smoke in from the nail salon for an extended period of time without any sign of smoke showing in that business.  Then after approximately a 15 to 20 minute period of time, the pizza restaurant quickly filled with smoke.  Still no smoke showed in the Nail Salon.

As it turned out, there was a shared enclosed void that had an opening above the water heater in the pizza restaurant.  The leak was far away to be sure at the other end of the void and it took time for the void to fill with smoke before it would exit the opening.

There was likely a cut off vent stack hiding at the far end of the void. It was up to the property owner to chase it down at this point.
After years and years of sewer gas issues with I don't know how many contractors and agencies involved, we solved the issue in just a couple of hours.

"I'm still shopping around." Searching for the cheapest price on hydro-jetting.

I can't tell you how many times as a vendor I hear, "I'm still shopping around, I'll call you back."  It's frustrating as a quality vendor because I know that in the end their sole consideration is price.  They are assuming that everything else is equal.  They assume that Hydro jetting is the same from one vendor to the next and nothing could be further from the truth.  I try and educate people as to the differences to look for but some people don't want to hear it, they just want the lowest price.

Ok, so when people tell me "this guy will hydro-jet  for $250 or $200"  I tell them, "use him, or better yet, go to craigslist and put a want ad for hydro-jetting and put a price of $150 or $100."  Without a doubt you will find someone but it becomes obvious to them at that point that maybe going the cheapest rout isn't the best idea.

Let me give you a "for instance".  When I was a young man I had a plumbing water leak in my newly purchased home.  I had a home warranty with one of the national home warranty vendors so I let them take care of it instead of doing the work myself.  Well if your not aware of how the home warranty business works, I'll tell you.  They send out a contractor that they have struck a deal with and they pay that contractor a very small per visit fee, maybe only $50 dollars or so and the contractor picks up a small check from the homeowner as a co-pay as it were. So the combination of the two payments still adds up to a very small service call fee for the vendor supplying the work.  

Well what happens is that you end up with a lower quality of service provider that is willing to work that cheaply.

In my case,  when the "plumber" arrived, it was obvious that this man had spent more than a little time in jail.  He was covered with jail house tattoos and he was not someone I wanted around my young wife and children. I would have gladly spent an extra $100 just to keep that man out of my house.  So you see, everything isn't equal.



The best thing to do is research. The internet is an amazing tool, use it to your advantage.  Just a little bit of time online will give you a pretty good idea of who is competent and who is not, of who can be trusted and who can not. Be wary of the one stop shop websites that say they will provide you with a great contractor.  Again, use the internet for reviews of each specific service provider by name.

We have an amazing amount of information online at our website that tells you what to ask to allow you to compare one hydro jetting vendor to the next.  www.superjetdrains.com

Disposal plumbing problems and don't put that down the drain

Customers don't want to hear it but I always tell them. Don't put anything down the disposal. It's not worth it. A great majority of the calls for clogged drains in a home come from the kitchen line and that is a grease issue. Wipe grease out of your pans out with a paper towel and throw that into the trash. Put all food waste into the trash. Never never never dump hamburger down the disposal. It's loaded with grease. All those fats,oils and grease collect within the pipe over time and cause problems. Sometimes they cause major problems. A heavy grease problem can't be cleared with an ordinary snake or cable. That means you'll have to have it hydro jetted and that won't be cheap. You think the disposal is a convienence but in the long run, if your using it instead of a trash can, it's going to cost you.
I use my disposal for the small scraps that get past me. That's it.
Now let me talk about the toilet as a disposal. I can't tell you how many times I find whole food in a sewer line overflow or backup. It amazes me. I've seen macaroni noodles, watermelon, the list goes on and on. The only way for that to get into the line is via the toilet. The toilet is not a disposal. Never put anything down the toilet but toilet paper and your business.
Don't put tampons, feminine napkins, baby wipes, kitchen wipes,dental floss or food down the toilet. They do not dissolve. They will migrate to the first turn or restriction and start a backup. I know the tampon packages say flushable but they're not going to reimburse you for the plumbing call. I had this one customer that had been dumping her cats litter box down the toilet. You can't rooter that out with a cable machine. It has to be Hydro jetted. It took us a couple of hours but we were literally able to pull a huge amount of that material out through the clean / out and onto the ground. It had to be about 10 to 15 pounds of material.

When to Hydro Jet or How to not get swindled on your sewer repair

We just finished a call for a local pair of clients. Two houses shared a common lateral sewer pipe run to the city mainline sewer in the city of Escondido, Ca. We were called to provide a bid on a sewer pipe liner to repair a seriously deteriorated pipe. The whole problem started with a back up as you would expect. The previous plumber had shot and provided a DVD to the homeowners of the problem pipe run. He told them that the pipe was seriously deteriorated and that the bottom was rotted out. I took a look at his video hoping to be able to use it to provide an accurate bid and save me the trouble of running my own camera. Well I was a bit surprised. I looked at the video and it showed that the pipe was full of heavy debris and that the pipe walls were heavily encrusted with scale and grease build up. It was no wonder that they were having backup issues. It was really ugly. The pipe was probably 50% to 60% blocked up with sludgy debris and large grease and pipe scale deposits. All a cable machine could ever hope to do would be to poke a temporary hole in a blockage. Not only that but because of the large amount of debris in the pipe, it was impossible to make any kind of an accurate determination of the condition of the pipe wall itself. It was a joke, the previous plumber is describing rotted out pipe to the customer and there was nothing on the video that backed that up. I can see how a customer doesn't understand that because he isn't used to looking at a pipe video, especially one that has a tremendous amount of debris in the pipe. I'm hoping to post the before and after videos on our website in future. http://www.superjetdrains.com/

I had a long talk with the two customers in front of the computer monitor as we watched the video and told them that my concerns were that the cost of a liner wasn't justified yet. A CCIP liner for the distance involved would be in the neighborhood of $4,000. I recommended a hydro jetting of the line to clean all the debris out and possibly remove a great deal of the pipe scale and blistering. It was an easy sell because the first step in installing a liner would be to hydro jett the line in preparation for the lining. I told them that after a careful cleaning, we would have a much better idea of what is actually going on. Based on what I saw on the video, there was a good chance that we would correct their problem with the jetting alone. It was $700 for the hydro jetting vs. $4,000 minimum for a sewer liner install. Well we hydro jetted carefully and thoroughly. We would hydro jet then camera then hydro jet and then camera again. We did this about 4 times before we were done. It was absolutely amazing the difference in the pipe. We completely cleaned out all the debris and were able to make the pipe walls round again removing the bulk of the heavy buildup of grease and pipe scale. The pipe went from about 40% to 95+%. The final video also revealed that there weren't any holes in the cast iron pipe at all and that there was a low spot or belly in the line which was clearly a repair that had been done in the street most likely by the city. This was all clearly visible on the video since the line had been hydro jetted.

If your plumber isn't able to clearly show you the actual physical problem on the video screen, be careful. It never hurts to get a second opinion and always be leery of anyone that says "you have to do this now!"

Never Never Never sign a lease or buy a building without a sewer inspection.

I can't tell you how many customers I have that are just sick. They hold leases on their restaurants or buildings and they come to find out that they have major sewer or drain line problems that have clearly been there prior to their move in. Unfortunately most commercial leases that I am aware of make the tenant responsible for all the drains and sewer lines within the building up to the mainline tie in outside of the building. I have a sweet lady, we'll call her Edith. She has been in this restaurant space for 6 or 7 years and she has constantly had to fight various drain problems. We have smoke tested her place several times on different occassions because of very strong sewer gas leaks within the building. We found degraded vent pipes in the walls and in the drop ceiling. These sections of degraded pipe allowed sewer gas to enter the building and it was affecting her business in a big way. We find and fix her problems when they pop up but there is a cost. The cost of the test, sometimes the walls have to be opened then repaired and then there is the business lost. That's just the vent pipes.
She also has regular sewer line backup issues because of degraded cast iron lines. Some lines are old and very rough. Sometimes this can be helped a bit with hydro jetting. Hydro Jetting with a large powerful machine can smooth out this rough pipe to some extent but if the pipe is getting thin with age or worse yet has holes in it, there isn't alot you can do short of major repair. The repair costs for what Edith is facing are easily in the ballpark of $6,000 plus. All this falls on her because of the way the lease is written. Take a look at the following link that shows a video of a seriously cracked sewer pipe that runs just under the corner of an apartment building.
http://www.superjetdrains.com/videos.php
We were able to line it with a cured in place pipe liner. If we had to excavate things would have been very expensive.
I would strongly recommend to anyone who is considering buying any sort of a building or leasing a property that they perform a camera inspection of the sewer and accessible drain lines. I would suggest a sewer and drain expert or specialist as opposed to just a run of the mill plumber. The specialist is going to have a much better understanding of what there looking at because it's all they do. If your in Southern California, give us a call. SuperJet Sewer and Drain Cleaing. SuperJetDrains.com It is what we do.
A visual inspection will quickly locate problems like a severe belly or low spot in a line that acts as a collection spot for debris. These are very often the cause of repeated backups. These cant be fixed short of digging it up and repairing it. ( We just did a diagnosis inspection of a beautiful house worth over a million dollars with a wide open floor plan and a long span across the house covered in beautiful stonework. The sewer line runs across the house under this same stonework and is plauged with multiple low spots or bellies in the line that regularly cause backups. The only way to fix this is to dig it up and regrade the pipe run. His only other option is to hire us on a regular basis to do a preventative maintenance with Hydro Jetting the sewer line.)
The other thing that comes to mind is that now many cities are making the homeowner responsible for the entire sewer lateral that runs from their house all the way to the cites mainline tie in point in the street. This is serious stuff. If you have a problem in that run after it hits the street, the cost to repair can be huge. A common number for a repair in the street with all it's additional issues, permits, certifications and costs can go $30,000+ very quickly. Think about that for a minute. How many houses or properties have you bought and did you ever do a sewer inspection?
One last thought, I do this for a living. About 50% of the time when we run a camera to inspect a line for whatever reason, we find a problem.
