    Bad hot water pressure

    Hello, I just moved into a flat and it's all electric. I have a boiler which has this written on it: "Albion the cylinder people, economy 7 cylinder, fitted with sacrificial anode. J Baguley & Sons Ltd, max heater 14 inches/350mm"

    Although my cold water pressure is excellent, my hot water pressure is poor.....it trickles out of my kitchen tap and also my bathroom tap (although the bath tap which is nearest to the boiler is okay).

    The boiler has the main cylinder and a header tank on top of it - it is just above head-height. I've tried turning the red tap and also adjusting the ball-a-fix valves, but to no avail. Any ideas on how to adjust the pressure or what might be causing bad pressure? Could the inside of the pipes/header tank need a clean??

    Can I get a pump to force the water out quicker?

    I assume that these boilers are meant to be able to do the job, otherwise they wouldn't make them. Any ideas?

    Thank you so much,
    Steven P.

    You could use a pump but this might not work for showers. As an alternative you could fit a pressurised tank.


    Good luck!

    Had large spider blocking the 1/2" outlet in the header tank which reduced the hotwater pressure -- could be a similar blockage

    put flower pot upside down with cut away on lip over the outlet to stop futher problems

    Since the hot water supply to your bath tap is satifactory there is nothing wrong with your system, up to there.

    The problem is downstream and is almost certainly a restriction of some sort.

    I think it is unlikely that the pipe is significantly furred up. More likely is that the taps on your kitchen and bathroom sinks are not opening fully because there is some furring on them. It is also possible that isolating valves have been fitted close to these taps , to facillitate servicing, and that these are not completely open.

    Do not start spending a lot of money until you are satisfied that the problem is not cured by simply looking at the pipes and stripping and cleaning the internals of the taps that are giving you the problem.

    It could be possible that the pipes for the taps are 1/4 inch (old pipes) and the batch is 22 mil

    If this is the case the boiler will be pushing out water along 22 mil pipes which flow into 1/4 inch pipes (which are bigger), this would cause preasure loss

    Just been reading through this and I appear to have the same problem. Just had a new bathroom fitted and the hot taps for the bath are extremely slow compared to the rest of the house. I know that the plumber had to fit the 1/4 connection fittings as thats standard now for the new taps etc. How can this be fixed? It take 1/2 hour to fill the bath up :-0

    We have recently movedinto a 2nd floor appt. The pump is working well with the cold water, the hot was never good.

    the other day it has been reduced to a trickle from both the shower and the hand basin. The kitchen remains the same however. Any ideas? CoLm

    Re: Bad hot water pressure

    I seem to remember having a similar problem in my old house and it was resolved by 'bleeding' the radiators. Empty the valves slightly and let the excess water drip out - it may or may not help, but it's worth a shot!
