I need to pressure test a new gas line. I have a gauge installed on that line downstream of the meter. The problem is I have a pressure regulator (Itron B42 itron-b42-series-residential-and-light-commercial-regulator-spec-sheet.pdf) that does not allow any pressure build-up downstream. How do I either isolate it or set it for the pressure testing? Is there an adjustment on this regulator for pressure testing on the outlet side?
Thanks.
a. Mount a pressure gauge downstream of the regulator to monitor the downstream pressure.
b. With the downstream pressure valve closed, slowly open the inlet valve.
The outlet pressure should rise to slightly more than the setpoint.
Verify there are no leaks and all connections are tight.
Marq1: How can I remove the regulator without removing the meter? Should I remove the meter and cap the outlet? The meter is 10 PSIG MAOP.
PJmax: This is the startup procedure. I want to pressure test the new line before the startup. Is there a way to do it without disconnecting the meter? Perhaps, by setting the regulator in the correct mode.
Thanks. Adding to the existing system. Will I need to reset the meter once it is disconnected and then reconnected? I think the pressure regulator will need a reset by pulling the plunger.
You cannot get a foolproof leak test using pressure with the meter still connected.
But you can try this:
1. Seal up the system downstream of the meter.
2. Attach your gauge.
3. Pressurize the system using the incoming gas pressure.
4. Turn off the main gas valve.
5. Wait the prescribed time.
6, Note whether the pressure on your gauge held steady or was lost.
You should not need to break the gas company seal to do an official leak test. Unhook only the load side of the meter. Seal the end of the pipe and do the test with your own air compressor or bike pump...
What seal on the meter are you referring to? I don't see a seal on the 2 large nuts on top of the meter. Where is it? Which seal am I opening if I unscrew these 2 nuts?
Why do you think testing it with gas will work? I tried adding a little bit of air through the test port (downstream) and all air comes out through the pressure regulator. The pressure dial does not move even a little bit. I can hear the air hissing out through the test port if I push the pin with my finger an hour later, so it is not wide open and holds something, but not much pressure can build up. I suspect it is set to something like 7 w.c., by design, which is 0.25 PSIG, and I am not detecting it with my gauge.
On second though, I think that all gas appliances should be disconnected from the section of gas plumbing in question before doing a pressure test. Not sure whether a multi-PSI test will seep through ordinary gas cocks.
A few years ago there was a failure of a regulator in a street in the Andover Mass area causing excessive pressure in gas mains serving hundreds of customers. Many appliances were damaged. This suggests to me that testing using pressure more than twice the 6" water column or 0.25 PSIG household pressure can endanger appliances.
Hello,
I’m trying to remove the P trap under my bathroom sink to clean it out however, I can’t seem to loosen one of the nuts. In the attached photo, I’m able to loosen the nut circled in yellow but can’t loosen the one circled in red. It doesn’t appear to be cemented together.
I purchased a universal plumbers wrench but it seemed to be too small. Tried an adjustable plumbers wrench but it started to gauge the ABS plastic so I stopped. I returned both tools and recently tried a nylon strap wrench but had no luck. The stores are all sold out of other strap wrenches so I’m not sure what to do next. any suggestions for next steps? If I purchase a universal plumbers wrench what size will I need to loosen the nut circled in red? I labelled the dimensions of what’s written on the pipes.
Thanks in advance!

I live in an apartment. The bathtub faucet has had a hole on the bottom side since I moved here about nine years ago. The hole is directly below the shower diverter. The whole bathtub faucet canNOT be replaced. Need to plug or repair the hole on bottom side of faucet because it has gotten so large most of the water continues to come out of the hole. When the shower diverter is pulled up to activate shower very little water comes out the shower head. Most of water is coming out of the hole on bottom side of bathtub faucet where the bottom of the shower diverter has hit the bottom side of the bathtib faucet making hole larger & larger. Now the hole is so large I am unable to use my shower until hole is plugged or repaired. Replacement of bathtub fixtures is NOT an option. Please let me know how I could plug or cover hole on bottom of bathtub faucet. The hole is exact size of shower diverter approximately 3/4" in length & 1/4" in width. I can actually feel the bottom of the shower diverter coming through the hole when water is off. I can actually push shower diverter up a little through the hole. Other than the hole on bottom of bathtub faucet everything else works properly with my shower & bathtub. Just need to repair or plug that hole. And I have no idea what to use for this repair. Sure hope y'all know of a simple & inexpensive DIY to plug or repair the hole. Thanks, Marcie
