Hi there
I woke up this morning and my boiler had no pressure, so I had no hot water.
I turned the little taps under my boiler and brought the pressure back up. Lovely, all warm again….
but, now my water pressure has significantly dropped and my hot shower and taps are less powerful than previously. Cold are fine.
It would happen on a Sunday and Mothers Day!
Any one with any experience or advice? Obviously I’ll call someone when I can, but I’d like to know what to expect in terms of fixing it.
Thanks

Boiler and water pressure question

My plumber told me to always bleed the radiators after topping up the pressure in the boiler

Low pressure or low flow ?
turn your cold tap on and put your finger on it if you can stop it you have low pressure
if you can’t stop it check your internal stopcock is fully open sometimes bits of debris can get behind the tap and reduce flow
check the refill valves on the boiler are where they should be
a small drip shouldn’t make that much difference to the water at your taps

The leak may look small because the pressure is now low. It may get worse when the pressure is raised.
If the black nut is leaking it might be loose. Tightening it may help. But if it was incorrectly fitted tightening it may not help. It looks quite new. Can you get the installer back?
When looking for leaks, go outside. A small metal pipe comes out of the back of the boiler and goes through the wall. It squirts out (usually hot) water if the pressure is too high. It is bent round to squirt against the wall to avoid scalding anyone. Once it has released it is liable to drip.
