Blocked gas pipe

GAS COCKS & FILTERS

had this before. sounds to me like the meter governor is knackered. works fine for days then all of a sudden the gas stops and restarts intermittently. working pressure fine when tested at both ends. get transco to swap governor. claim low working pressure they'll be pretty quick to come out.

Found the problem. Water in the pipe. I blew it through the other way and got easily a pint out if it.

I then rigged the compressor up with the meter end blanked off and high pressure tested it. The patio outside started bubbling when I threw the lever valve. So tomorrow I'll have the apprentice dig it up and go from there. Cheers for the replies everyone.

Would offer to help the poor sod but i have an office to fit out

So the lad dug it out today, and as fast as he could dig the hole filled up with water!

Got the pump and cleared it out. Found the problem. Leaking joint. I'm amazed it hasn't become a problem sooner. I'll be cutting the leaking joint out tomorrow.

It's a piece of yellow MDPE stuffed into a 28mm compression fitting, with epoxy resin squidged around it.

We need to dig further away from the joint so I can cut the pipe and put a proper union in. Shocked. It was peeing out gas.

The bubbles in picture one are with the compressor attached, not bubbles from the pump. It looked like a jacuzzi.

Must have been leaking a while. When we removed the dodgy joint I found a 28mm compression coupling stuffed into the 32mm mdpe gas pipe. Then some epoxy resin had been smushed around it. What a cowboy.

We worked until gone 8 and it was in some mental storm. I had to drop the pop up gazebo as it was going to blow away. Soaked through to my under pants but got the couples gas line blown through, tested, purged and the boiler on. So they were happy!

Nice one Danny, " most would have walked away, more so in this weather"

Well played mate, the kind of job that makes you wanna cry!!

Was it the gas networks that done it then? crazy stuff

No, I don't think so mate. Customer isn't sure who fitted it as the run was altered 15 years ago when the extension was built.

It must have been leaking a while but it's only now the water table is so high it's blocked the pipe. Somepeople just don't care, and some are just incompetent. I'm not going to judge it, just pleased to have it done.

We were cold and wet yesterday, and as I sweated the new 28mm coupling in place, the solder didn't run. Even though I had cleaned the joint I think it was the residue from the denso tape. So I cut the coupling out. Went to get another from the van. I was out of them! It was about 7.30pm. So I went back to my lockup and grabbed some, and back to the job to try again. At that point, crying was possibly an option! :0

Always get a better sense of satisfaction from a difficult job though!

Very true mate!
