Dripping into tundish - turn water off?

[daviddlow]

Hi folks -

We have cold water passing through the tundish and out to the overflow pipe pretty much 24/7. I can't get a plumber out until Monday.

There is no other reason to have the boiler on just now, is it safe / preferable just to shut everything off until the plumber can get out? I turned the cold feed off temporarily and the drip completely stopped.

Many thanks!

David

You can turn off the electrical supply to boiler yes. If you're isolating the cold feed to cylinder how do you intend to have hot water?
Furthermore you must ensure any technician working on an unvented cylinder is G3 certified.

Thanks for the very quick reply. We were going to do without hot water and maybe use it as an excuse to escape for the weekend now we're allowed to!

If I leave the cold water running, the external overflow drip is constant and running onto a gas meter box which I'd rather not have. But of course that means no water.

I'm assuming British Gas Homecare would send out appropriately qualified staff for a job like this, especially now they do triage on callouts, but thank you for the heads-up on G3 certification too. They installed the system so you'd hope they're competent!

If you can safely get away for the weekend then I would take this opportunity and isolate everything in the house while away.
I'd hope the attending engineer is competent and I'm sure they are certified but British Gas aren't always the best unfortunately.

If it is an unvented cylinder and its not discharging within 4" of ground level then its incorrect and needs addressing. Water at high temperature and pressure could discharge from there.

It's discharging one storey up, directly onto a garden and next to a pensioner's front door; the pipe bends in towards the wall but barely. When the boiler was replaced, the boiler got a new overflow into the ground, but the tank pipe was left alone. Should I get that seen to?
