Help! Low hot water pressure in kitchen after replacing bathroom taps.

[TanyaB]

Good morning

I have an open vented gravity fed system and had a leaking tap on my bathroom sink so decided to replace both while I was at it. I turned off the valve to the immersion heater and ran the taps until nothing came out and just replaced the innards of both taps like for like and put them back together.

When I turned the water back on I have great hot water pressure in the bathroom sink but virtually none in the kitchen and utility room, cold pressure is fine. I drained the system to see if it was an airlock but it's still the same, the kitchen and utility room hot taps don't splutter or anything, the water just comes out at a steady trickle. I have spent days trying to find a solution but have come up against a brick wall. Can anyone please help me? Forgot to add it's a bungalow..

Thankyou

you have an airlock. the easiest way to sort this is to connect hot and cold washing machine valves together with a WM hose, open the hot first then the cold and give it a short blast of mains up the hot. it works 999 times our of 1000. that's assuming you have hot and cold WM feeds of course.

Thanks! I'll give it a try today

Or, if your kitchen sink has a mixer tap you could use it to put the mains water through the hot, same as Steveb means.
If it was a really old mixer tap, the hot and cold mix in the mixer spout and all you need to do is hold your hand, perhaps using a cloth over the end of the spout and first turn hot on and then turn the cold on for a few seconds.
But your mixer is likely to be more modern and the spout would need to be removed and your hand put over the mixer body. Getting the spout off might be hard though

My washing machine only has a cold feed as the hot is blanked off and my mixer tap is very modern so not sure that I want to fiddle with it. I tried to put some hosepipe between the two taps in my utility room but it's too narrow and not flexible enough so I'll have to go and buy something with a wider bore and try that. Thankyou for your replies!

Or phone a plumber that would be an easy choice
