Is there any reason for having a liquid flow switch fitted to the cold water feed of my Worcester Bosch combi boiler? Had an Engineer out as the switch is leaking. He couldn't see what purpose it was serving. Options given are replace (but its an £80 part) or remove and cap off. Thinking...

Hi, I am mounting a wash basin and using the fixings below in the photo. It is going in a new build part of my house and so I know the wall construction and hence could measure accurately from the external plaster finish to the block work behind. Seems to me that to ensure that the plug...

Hi, Trying to remove the tap head on the tap shown in the pics. I managed to get the screw out of the top of the head below the "C" cap (screw head completely worn away). I assumed with the screw out and with just a bit of elbow grease it would then pull off to reveal the valve. The tap...

Hi The attached pics are a cross sectional view of the pipe work coming out my kitchen sink U bend which connects first fix plumbing to second fix. Question I have is whether the slight upward gradient is a cause for concern? The upward gradient only runs for the length that is shown in the...

Hi I have a water underfloor heating system in one room. It has worked without fail since installation about 4 or 5 yrs ago. We have been having some building work done and as part of this the supply pipes to the UFH were cut and re-connected. I have a feeling the pump may have been on when...

Hi Sure this is a very straight forward question but I'm just not familiar with plastic plumbing pipes. Just had new extension built and in a utility space where intended for there to be a washing machine and dishwasher the first fix plumbing has just left a waste pipe sticking out of the...

I have a ferroli optima 700 boiler that gives CH and hot water supply. In one room I have an underfloor heating pump and underfloor heating. Connected to the boiler is flow valve so that if the underfloor heating is on and I need hot water elsewhere then the valve diverts it to domestic hot...

Hi, I've posted a few questions on this before, tried a few things but not really found the solution (though thought I had....). I've basically got a combi boiler (Ferroli Optima 700) losing pressure ever since I had it serviced. I've since had the PRV changed and I check the outfall...

Hi, Been trying to get to the bottom of gradual pressure loss on my Ferrolli combi boiler - I'm sure it isn't to do with the PRV, I had this replaced recently and have been checking the outfall regularly when the boiler been on for a while and its dry. My plumber says there must be aleak...

Quick question ? Is it normal for my Optima Ferroli combi boiler to increase from a little over 1 bar water pressure to 2.5 bar pressure after it has been on for a while. Assume the PRV kicks in when it gets too high ? Thanks

Hi Had my Ferroli Optima combi boiler serviced a few weeks ago. As part of this the Engineer released water pressure through the Pressure Release Valve. Boiler fine since but gradually over seven day period it loses pressure dropping from 1 bar to nearly 0 bar. I bled radiators and then...

Hi Wonder if anyone can give me some advice? A switch on the main electrics board in my house for the downstairs lighting circuit keeps tripping - this switch being one of maybe eight which presumably are for other circuits. Not really sure what the official word for these switches is...

When I moved into my house there was an approx. 3 mm thick grey wire extruding from the brickwork at the back about 2.5 metres from the floor. I figured out this was connected to a switch in the nearest bedroom which has a fuse point and light below the switch. I wired the cable into a...
