Hi, Hope you can help, getting to my wits end with this one... We have a positive, vented system (cold water tank in the loft) with a Salamander shower pump (1.5 or 2 bar I think) powering two showers. The pressure used to be superb but recently its less than it was. The pump is still...

Thanks again for the info - all makes sense when you hear from someone who knows what they're talking about. Needless to say, I've cancelled the cheque...

Thanks for the prompt reply guys - as predicted, there's water very slowly dripping from the "circular brass lump" onto the "chocolate box" connectors and wires below. Electricity and water? Hmmm... Is there a fix for this or do I need a new brass lump? (Sorry if I'm getting technical)...

Hi, Sorry to post *another* sob story about freezing in one part of the house, but any suggestions gratefully accepted. Here's the deal: - Rad in basement, possibly furthest from boiler - Combi boiler, so I'm assuming a closed system - rad has a lock value on one end and a thermo value...
