    Pressure or flow rate reduction?

    Hopefully this is a daft enough question to get a simple reply. I have fairly high mains pressure which is good for the shower, but means that the cold water tank in the loft fills fast and quite loudly even with a quiet Fluidmaster fill valve. I would therefore like to slow the fill speed down...

    Single overflow from cold water storage and CH header?

    I realise this may be a chronically stupid question but I'm going to risk asking it anyway. I had my flaky facias & soffits replaced today.

Realising that...

    Air drawn back into CH system through vent pipe?

    This is a bit of a saga, but I will try and be brief. In August 2004 my warm air system packed up, so I forked out for the installation of a fully pumped Honeywell 'S' central heating system. Everything worked great, but there seemed to be a lot of air circulating noisily through the...
