Hi, I have a gravity system (hot and cold) and looking to get the best out of it by fitting a water pump for the hot feed. The existing cylinder flange already looks to be an 'S' flange (conveniently) but does look to have too many adapter fittings making it too proud to be effective - or would...

Hi I am looking to create a ‘warm roof’, there is no insulation currently. Can I attach PIR boards over the rafters to save on cutting them? The roof is also vented, so how do I accommodate the vents?

Hi Oil boiler is rumbling every so often - is this air, water or contaminated fuel getting into the burner? I can't pick up any oil leak around the connections.

Hi Trying to work out how my heating is plumbed, why would output of S plan 2 port valves be also bridged by a gate valve (normally shut) ie the heat output from boiler goes to x2 two port valves - one for HW and one for CH, but why provide a means to bypass them? by the way I have a wood...

I was looking to sort out flooding issue when it rains heavy at front of house, with maybe connecting an Aco-Tray to the existing drain then uncovered a few issues with the existing drains that I need to repair first (always the way). Some advice please.... As per the photo - can I keep the...

Hi I am looking to install a shower one side and the toilet the other, so I need to join the two wastes together. It is best to extend the 110mm to the outflow of the 40mm and join up there with a 40/110mm adaptor? Does it matter where the stub stack with AAV will be - assuming I just need...

Hi I have an electric shower in the en-suite that takes it cold feed from a T off from the same pipe that feeds the 2 header tanks in the attic - so it must be the mains. From that is a smaller bore copper pipe of about 2.5m length to the shower. However the flow changes from 2 to 4 l/min. What...

Hi All, Struggling to find a plumber, so tackling this myself. This is a new install (single storey) so will need waste piping all way to the exiting septic tank. Would like to run a few things by you.. Would a 'stub stack' the way forward with this? With boss pipe for the x2 40mm wastes then...
