We had to replace a gas water heater last Wed in the basement of a duplex and all went well until last night when tenant smelled "something". I checked basement first and smelled gas, not strong but there. Nothing could be smelled in the unit and I left basement door open to vent. They have a gas furnace, water heater, and stove. This AM my handyman and I went over all the pipes and connections with soapy water and found a small leak at a nearby connection going to the stove. We were able to get it sealed and I rechecked about an hour ago and noted no smell. The pipe appears to be a thoroughly rusted iron and I would like it replaced by a contractor.

Things I need to know?

"What you needed to know". You should have detected the gas leak during the replacement of the water heater in the basement. Second, a "contractor" is not a plumber. A general contractor can take on jobs involving several trades but can not contract for a specific trade such as plumbing, electrical or roofing by themselves. You need a specialty contractor to work on pipes, gas and water lines -- a Plumbing Contractor.

Was your leak on the threads of the pipe (at a connection)? Simply because you have some surface rust doesn't mean the pipe need to be replaced. Only an expert can make that determination.

When I suspect a gas pipe bad, I want to determine if it's a seam in the pipe or a bad fitting connection not using pipe dope. I also will "pressure test" a pipe for leaks. This also has to be done by a plumber. If a Contractor without knowledge hooks up a pressure meter at on end of the pipe and simply shuts off a valve connecting the pipe to the house gas supply -- they could blow up the house. You want to cap off the line being tested and isolate it from live gas.

One time the owner across the street from my 4 unit replaced a water heater in a tenants laundry room. The gas cock was old a defective, but the old owner didn't want to spend $12 for a new one. So I started to smell gas from across the street. Ran over to the building and smelled gas seeping out of the back door. Before I called the fire department, I had a cellphone built into my van, I shut off all gas and power to that property and made the tenants exit. Had a tenant in that unit flipped on a light switch, the building would have blown up.

Thanks Robert, the contractor is a plumber/HVAC man. My handyman did do a leak check at install. He did not check the entire pipe in basement away from the heater. I now want someone who is licensed as a plumber to go over the entire setup.

Last month bought a furnace from a contractor where noticed on the old furnace that smelled gas near the gas valve. After sending a few emails to the contractor that wanted furnace changed ASAP where when contractors came told them about gas smell near gas valve where when contractors removed old furnace they said the gas pipe was hand tightened where a wrench should have been used. Not knowing if the gas was leaking or the pipe was leaking. Surface rust can be cleaned up with wire brush where it is rare the pipe will rust through. Black iron is very cheap where can buy at most big box stores for 5 dollars or less depending on the length of pipe. When the furnace was replaced supplied new CVPC piping along with a new concentric vent as ABS pipe is not allowed on new installations so the exhaust and air intake was all replaced where it is very rare for ABS to fail with a high efficiency furnace. Most common problem is there a leak on the threads of the gas pipes where new pipe joint along with tightening up the fitting then checking for a gas leak with a soap test where no bubbles no troubles.

My black steel gas lines were 55 years old with old school pipe dope on each joint.

Every once in a while Iíd get a slight wiff of gas when in the basement. I bought a gas sniffer $100? and checked the lines (good tool for every LL to have). EVERY threaded connection had a slight gas leak due to age. The threads are the thinnest part and most vulnerable.

The multiple tiny leaks could have created a puddle or cloud of gas that would have exploded when it it the WH pilot light.

We replaced the entire line from meter to furnace & water heater.

Flex line makes this easy.

In a rental we had a hairline crack on the back side of a brand new gas elbow. Found it with the sniffer. Because it was facing away we could ne see bubbles.

I would say that what you did was "playing with gas"

I am shocked at your cavalier attitude

1 call from a tenant about a gas smell and they would be out of the house on the sidewalk waiting for the emergency HVAC tech

In many places what you did is illegal

all I can say is WOW --73.61.xx.xx

In Maine a licensed gas contractor is required for all gas work. However, that doesnít always happen. One day, while working at HD, I assisted a customer who was getting ready to install a gas stove. He clearly knew nothing, and his assistant (me), knew even less. I called for someone from plumbing to assist him. Iím surprised I didnít hear about some sort of incident in the next few weeks. I donít dabble where I know nothing.

A couple years ago in a local city a guy messed with a gas boiler and didnt know what he was doing and the house and houses on both sides were destroyed by the blast. Myth busters created a situation where they intentionally blew up a water heater and it flew in a air through a floor and a roof for an incredible distance before it came down

Gas line (by Lana [IN]) Posted on: Jan 11, 2021 12:18 PM

Thanks Brad, I bought a gas sniffer to arrive Wed. Yes we install our own gas water heaters, stoves, and even wall furnaces, but not central heat. My current handyman works with his cousin a lot who is a certified plumber, and he has been with me 6 years. The water company today came for a leak check as the old water heater blew a big water leak through the control panel and the first sign of trouble was a high water bill. The water company guys did not smell anything, but I still can. We are venting the basement and I have three plumbing companies I have worked with contacted. Only one call returned and they cannot come before Friday. Nothing found today with soap film.

Gas line (by Steve [MA]) Posted on: Jan 11, 2021 12:55 PM

Lana, in my are if there is a smell of gas the local gas provider (National Grid in my area) will send someone out right away to check on any possible gas leak. The local FDs will also come check on this.

A few years ago there was a major gas explosion that caused at least 1 death & millions of dollars in property damages.

Columbia Gas Explosion in Lawrence County. On Sept 13, 2018, Columbia Gas accidentally over-pressurized a gas main that fed thousands of homes throughout Lawrence, Andover, and North Andover counties. The over-pressurization of the gas main resulted in explosions and fires that killed one person, sent 22 others to the hospital, damaged 131 structures, and destroyed at least five homes. 30,000 customers were forced to evacuate their homes and seek shelter elsewhere due to unsafe conditions

Gas line (by Ken [NY]) Posted on: Jan 11, 2021 2:37 PM

Steve,I remember seeing that on the news

Gas line (by Jkj [MA]) Posted on: Jan 11, 2021 6:44 PM

Steve, I was on duty and we were sent to Lawrence to assist with the resulting fires! As soon as we knocked 1 fire down we were sent to another location. I donít think people realize what it took to get that event under control. There were fire departments from all over MA and NH.

Gas line (by Jkj [MA]) Posted on: Jan 11, 2021 6:52 PM

I read not to long ago that that event potentially could cost NiiSource (Columbia Gasís parent company), 1 BILLION dollars!

My 2nd contractor I contacted called back and came at 1530. We went to basement, we both smelled gas, and he found a leak. Leak was at the connection low and right at gas input to heater. Leak was repaired and we went out to gab for about 10 minutes and both went in and neither of us smelled gas. I have rechecked twice since and it smells like a slight basement odor. Rechecking in early am and I have a second contractor who was coming at 10 tomorrow. I will cancel him if it stays normal. Plumber tonight said pipes look OK to him. It was my handyman not double checking his work when he leak checked. I will continue to ventilate basement until Wed. Will spend rest of month checking all my gas lines in 9 units with gas.

Gas line (by nhsailmaker [NH]) Posted on: Jan 11, 2021 7:35 PM

WOW - still thinking you should play with gas

Not calling a licensed professional in GAS GAS GAS is simply astronomically #^%*$^^#^* --73.61.xx.xx
