Hi I think you have a few issues here. Firstly I cannot see that the bath filling problem has anything to do with the shower. It seems your hot water flow rate is poor. If the hot water to the bath fills slower than it used to (or slower than your neighbours) there may be a blockage or air lock in t...

Hi Firstly I wouldnt do it myself. I have known people use a solar system to fuel an immersion heater but not with a combi. You could change your boiler to a condensing system boiler and make the necessary alterations from there. However, I suppose if you set up a separate hot water system alongside...

Hi I would first turn the water heater off for a few hours and check the cold water then behaves normally. You can then be sure the warm water is heated by your water heater before entering the cold taps. If that is the case it can only be getting there via a mixer tap or shower (or possibly the hea...

I sometimes use a 20ml syringe with a section of transparent flexible pipe attached
Not 100% effective but worth keeping in the toolkit.

Water head pressure is static pressure caused by the weight of water solely due to its height above the measuring point. The pressure at the bottom of a 40-foot lake or a 40-foot high thin tube would be identical, since only height is involved. I just got this from the internet. It explained the poi...

Hi
The cold water to the kitchen will almost certainly be supplied by the water main.
The cold water in the bathroom most probably comes from the big tank in the loft.
Unless you have 2 big tanks in the loft it probably fills up the hot water cylinder as well.
Does the hot water work ok?

Barry Bunsen

It is probably the water flow that is concerning you rather than water pressure, although the 2 are linked. You should still get water flow upstairs when a downstairs tap is turned on with a combi but the flow will be reduced. Electric showers can go cold when the washing machine kicks in for exampl...

[quote="Barry Bunsen"]unless you want to fit a new tank in the loft and use it just for the shower via the pump[/quote] Sorry. Should have clarified. With a combi the tank would have to feed a pumped electric shower such as one that Triton produce, where the pump is part of the electric sh...

Barry Bunsen

Yes that is just about right unless you want to fit a new tank in the loft and use it just for the shower via the pump. Generally speaking a thermostatic shower will work fine in your case as the pressure is more or less mains pressure. If it was me I would pipe up straight to the shower. A useful t...

Interesting. I assume the tank is not the one that tops up the central heating. I also assume you have a traditional hot water cylinder and not a combi boiler. The cold water tank should therefore top up at least the hot water cylinder and possibly the bathroom cold water and the toilet as well. For...

Barry Bunsen

Your advice seems a bit muddled. To get true equal pressure you would need tank(s) in the loft for a cold feed and hot feed via a hot water cylinder, unless you settle for a complicated system with pressure reducing valves. You cannot balance the hot water side by installing a tank just for the cold...

Hi 3 different pipes! Didnt the water coming out of the first pipe ring any warning bells? Never mind. My guess is that at least one pipe was a central heating pipe and you have an airlock in the system - maybe in the boiler itself. The water would then be heating in the boiler without circulating p...

Barry Bunsen

Hi Usually when an overflow behaves like this it is because the ball valve is not stopping the water flow completely and letting just a small amount of water through. If the toilets are flushed regularly the excess water never reaches the overflow pipe. If they are not used the water continues to fi...

Hi
Sink and basin taps are nearly always half inch and bath taps three quarter inch.

Thanks for your reply stoneyboy. Looks good advice.
