No hot water pressure!

[jon13]

I have no hot water pressure in my home. Kitchen tap is ok with cold, slow with hot. Upstairs bathroom is ok cold, hot slow especially the bath. No pressure in the shower hot or cold. Water board say it isn't there problem, tried opening the stopcock right open but made no difference. Help!

How is the water heated?

 

[jon13]

is a combi boiler

how long have you had this problem?whats your cold water flow rate?

about 2 or 3 weeks. the cold comes out ok, not as fast as it did before though. couldnt say what the 'rate' is? The shower doesn't work hot or cold.

From your initial post sounds like you suspect a drop in mains water pressure, since you called out the water board. Is there a pressure reducing valve in the system ?

place a measuring jug under the cold water tap and measure how many litres per minute you can get

sounds like mains pressure related. could be a problem with stop tap - or even the stopcock in the road?

 

[jon13]

the water board say its not their problem if the cold water pressure is ok downstairs. i'll check the flow rate, is there a minimum?

ive also tried opening the stop tap more but this made no difference. any ideas?

I agree with all the posts here, there does seem to be a problem with pressure. You can test the pressure on the system by using a pressure gauge, you can probably buy one from B & Q or such like shop. Its normally 3 bar(ish).

The water board always say its not there problem. Speak to your neighbours and see if they have the same problem. Especially if they're on a combi boiler. Hopefully, they've got the problem and you can re-contact the water board and tell them it is there problem.

Your heat exchanger could be scaled up or your strainers may be clogged with debris.

Hi
It probably is something to do with the water board have you tried cleaning out the filter in the mains feed into the combi boiler as this could be relating to no hot water pressure
good luck

cold ground water is taking longer to heat. you may have a scaled up heat exchanger not helping much, but i'm sure you'll get better pressure when spring gets going.
