Help!! Took two hours to Fill bath

[fairywishes]

Hi please can you help my hubby turned the water off so to do with the upstairs bathroom ensuite sink so that he could fit some laminate flooring.
He correctly followed all the New house info folder on how to do this and turned it all back on correctly now there seems to be a mega loss of presure in the upstairs hot water taps. It starts out already half the normal output then trickles away to next to nothing... It just took me 2 hours to run a bath :0(
Please please help

usually involves geting wet.

If you have a mixer tap put your hand hard onto the end so no water gets out, put hot tap on and then cold tap on, this allows the cold supply to back fill the hot system right up to the header tank and blast away the air lock on it's way.

If no mixer tap but you have a washing machine connected to hot and cold. Remove washing machine turn off both washing machine taps, connect one of the washing machine hoses from one tap to the other. turn on hot then cold as above.

Otherwise you're stuck with the really wet method, hold a length of hose between hot and cold taps and hang on for grim death while water spurts out everywhere.

How long to do it for? Until when you let go hot water flows at normal rate and continues to do so. Doesn't take long.

What can go wrong? If the overflow pipe isn't up to scratch you could have a cascade of water coming through ceiling eventually but very unlikely.

If you follow my advice it's on your own risk and don't tell anybody who told you to connect a direct link between cold supply and your domestic hot water system without using a single check valve.
