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...

Ok thanks. Useful to know. Ill ask the plumber that did the first fix. Presumably for any fitting extending off the feed you turn mains water off, cut end off and fit. I only ask as the way it's capped off, i.e quite a soft thin cap made me think that there might be a novel fitting just to go...

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...

This has been resolved and was faulty valve on mains top up loop.

This was resolved and was a burnt out relay on the electronics board which only intermittently worked.

From your description it sounds like a similar problem we had. I'm by no means an expert but we deduced that one of the relays was faulty on the PCB since when all was working and you demand hot water we would hear two clicks, then when hot water didn't come on or was intermittent we only heard...

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 - thanks for replying. Since I posted I ran a test. Before I left for work this morning boiler had been off for the night and pressure when I got up was just less than 0.5 bar. I thought that it would be useful to start from scratch so I checked expansion vessel pressure and pumped this...

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...

Thanks for the pointers Gasguru - will look into the expansion vessel some more. Cheers

not sure what :?: :?: :?: is supposed to imply the comment is pretty self explanatory

Found the culprit - loose earth in one of the light sockets. Thanks for your advice

seem to be a lot of posts about re-pressurising a combi but not found any about increased water pressure ?

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

ok thanks will have a look

Ok - thanks for the advice. Will take a better look at it in daylight and sort that earth out - when you say the earth can be lugged and put on one of the fixing screws take it you mean just secured to the fixing screw - sorry not sure what you meant by lugged Thanks again

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...

Reading a few other threads and one thing I noticed is that in one wall switch the earth not connected to anything just loose albeit covered in sheath and bent backon itself. There didn't appear to be anywhere to wire it to though ? whereas the other switch boxes had an earthing point in the...

Hi Daytona, In answer you questions.. When I switch it back on it stays on for anything between 30 seconds to I think the longest being about 8 hours. It only started this weekend and I didnt go near anything that might have caused it (certainly didn't do any wiring like that Junction box...
