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.

A Superjet hydro jetting restaurant sewer line testimonial

Ok, so we've been hydro-jetting this restaurant in Rancho Cucamonga for two or three years at least, every 4 to 6 months or so. They have had zero problems since our service started. Well, last service we got stuck in the line big time. We had to really work at it but we did managed to get our hose back out. Mind you the owner is sitting there watching this whole thing happen. We ran a camera and we could see a large hole in the pipe at a turn area. I showed the owner but maybe he didn't understand what he was looking at. I gave him all the specs and marked everything out on the ground where and how deep the problem was because he said his landlord would take care of the dig and the repair.
So 4 or 6 months later they call us back to schedule another service. I asked him about the repair. He said "There was no repair, the landlords plumber came out and ran a camera. That plumber told them that there is nothing wrong with the pipe."
Things got a little weird fast. I said I can't hydro-jet the line. I know you have broken pipe. He assured me, "no the landlords plumber says it's not broken." I offered to hydro-jet if they guaranteed us a deposit for the hose if we got stuck. I thought that was reasonable based on the fact that I knew what was coming. Well he got pretty upset with us at that and told us he wasn't comfortable using us anymore.
Ok, so what can I do, some idiot tells him there is no problem and I know that If I hydro-jet the line there is an almost certainty that we will get stuck and he will have an instant emergency dig on his hands causing the immediate shutdown of his restaurant. We were fired and we've lost business because of some idiot "plumber".
So this is the fun part, guess what happens.
6 months or so goes by and we get a phone call from the restaurant owner. He wants to schedule another hydro jetting. It seems that the landlords plumber took over the hydro jetting for the restaurant after we were let go and you guessed it, he got stuck in the exact spot we had marked for broken pipe causing an emergency dig to repair the problem. We must have looked like psychics. It was nice to get the account back but it was priceless to hear the story from the owner himself.

Run that Sewer Camera If

Quite often I detect that hesitation in a customer when I recommend running a camera. I know that there are those companies out there that really push for that and use that as a way to generate more income at a higher cost to the customer but....It is an incredibly valueable tool that in the hands of a skilled operator can provide invaluable information.

We just finished jetting a job yesterday, an apartment complex where we hydro-jetted a short run of 75 feet that dumped into a mainline outgoing lateral and then ran another 185 feet to the city sewer connection.
The initial 75 was a restricted 3 inch wall c/o that dropped down into the run across to the next c/o. We jetted this with a medium hose and the appropriate sized nozzle. We hydro-jetted it thoroughly. Ran this probably 5 times slowly. The customer had mentioned from the start that they wanted to run a camera to document line condition so it wasn't an issue. When we ran the camera, whoa, surprise surprise, we found a very large belly in the line holding water right after the turn into the main outgoing. The pipe was almost completely full of water and there were a couple of very large grease deposits that truly looked like they hadn't been touched by a jetter even though we ran right past them 5 times. They were monsters and when they broke free, and they most assuredly would at some point, probably on a Friday, Saturday or Sunday night, you were guaranteed a back up.

The pipe being full of water was too much water for the medium hose nozzle to displace. You have to get that water out of the way so you can impact the grease itself. Without running a camera, you could never have guessed that.

The camera allowed us to make changes opting for a bigger hose with a very small nozzle and allowed us to know exactly where to spend our time and to verify visually to the customer that the blockages were completely removed.

If your having recurring problems, ie. having to cable every 4,6 or 8 months, run a camera. If you haven't run a camera in the last 10 years and your having an issue with your main line, run a camera. Think of it like a cancer screening at the doctor. If you can catch a problem before it gets too bad, your way ahead of the game. Two or three hundred on a camera could save you thousands.

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.

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.
