Hi there, I know that mains-fed storage tanks should be fitted with a high pressure ball valve, but does this still apply even when the mains pressure is extremely low and the tank is three stories up? The tank fills up so painfully slowly. Would installing a low pressure (ie larger bore) valve help or hinder? Many thanks.

You have verified that your valve is in good condition? Look out for any service valves, especially ball o fix type which obstruct flow. Some people turn down valves to reduce noise instead of correcting a fault.
You might also consider a 3/4" valve instead of your existing 1/2" one. It has double the flow and will run quieter.

I know this is 11 years old but its as relevant now as it was then.
In my search for the ideal valve, I have noticed that a 3/4" valve I bought actually had if anything a slightly smaller restriction than a 1/2" I already had. Both are part 2s. So I would think that connecting it would only be of any help if the existing pipework was 22mm and any increase in performance is due to the larger bore pipework and not the valve.
