No, it's lead and it disappears underground and I can't find where it reappears.

I'm guessing one of thise stud finders would probably do it but why didn't the pros try that? Also, is there a non groundworks version of a CAT and genny that I could use? Connect to any cold water pipe and use it like a stud finder?

Hi, I've got an underground leak and we're losing about 4m3 of water a day. We've had a plumber, a leak detector guy and a groundworks guy out to detect the leak. They all failed except that the groundworks guy used a CAT and genny to locate the pipe run. The pipe is lead and runs under the...

So, it was the bar valve that was the problem. I isolated it and the overflow stopped running (after about 3 hours!). I turned the isolators on again and the overflow started running again, isolated, and it stopped. Thanks to you all for assistance with this.

I think it's a dodgy bar valve. I went to do what Harry suggested and luckily I went into the bathroom without turning on the light so no noise from the extractor. I can hear a slight noise coming from the valve so i'm guessing that it's letting by internally. I'll change the valve as I'm pretty...

Okay, thanks, that make sense. I'll have a check around based upon that.

Is it not the other way around though? If the cold mains feed is getting into the hot gravity feed via a bar valve, then the valve connections will both be at the temperature of the mains cold water or am I missing something?

Yes, I do..3 of them...there's 1-ensuite, 1 in the bathroom and 1 in a small cloakroom. Is it possible to identify which one might be faulty. They are all bar valves.

Would crossflow on mixer taps or shower valves occur when they are not in use? The taps and shower valves are newish <3yrs old. I was here on my own this morning when I noticed the overflow.

Hi, I noticed that the overflow on our loft storage tanks were letting water by. I noticed that the water in the tank is quite warm and that the cold feed pipe going to the hot water cylinder was warm too. These are two 25 gallon tanks so it would take quite a volume of hot water to make these...

I see what you're saying. I'll drill a 10mm hole just above the lead and break out the bed below the weephole

It's capped with a flue ventilator

The building was built in circa 1850 so its quite likely that the chimney has been rebuilt. It's certainly been repointed within the last 10 years. The leadwork on the parapet is in good condition and the pointing on the front elevation of the parapet is good and it's rendered on the back...

Please explain Woody. Could this be the source of my damp?

Thought it'd be something like that so thanks for the heads up
