Boiler losing pressure

[milky71]

Hi all
I have a Baxi105e and my builder needs to repressurize it after moving radiators and fitting a new bath.

he refills the system with a filling loop but as soon as we turn a tap on we lose all pressure and dirty water comes from the taps (i presume from the ch system).

We can't remove the filling loop now as water gushes out.

A friend has turned all radiators off and we now seem to be able to get clean water but pressure is still being lost.

any advice would be appreciated

Yes, NEVER let builders loose on your plumbing!

Good advice but a bit late

Was on holiday when problem arose

Which way is the arrow pointing on the filling loop - towards the flow or towards the mains water?

no arrow on filling loop as builder made one that fits.

I am concerned that the ch inlet has been damaged as water flows despite valve being closed

"Builder made one"

Sounds dodgy and you may not have one with a non return valve.

This should do it.

Does your water slow to a trickle and then stop, if so he's probably connected the bath to your central heating system.

At least he didn't connect it to the gas!
