Denzo tape!! hahahah :roll:

A mates asked me to replace a section of there guttering thats leaking, so just wondering if its just a case of cutting the section out, getting some more guttering of the same kind, cutting it to size an snapping it back in place? or is there more to it than that? :wink:

Vokera are italian, and they are actually very good and reasonably priced imo I agree about ravenheat though, its insane they are still around with there sh**ty boilers

could be that there is no water going through heat exchanger so its over heating an locking out? cheak if pump is running

I once saw an old old school friend of mine, we got chatting i asked "whens the baby due" she replied "im not pregnant" to which i made my excuses and left sharpish!

the last meter or so may be run in 15mm (hence the 15mm connections on boiler) but the majority of the pipe work must be in 22 to allow the applaince to get enough gas to work efficiently and to its max capabilities

this isnt really the best positioning for a shower pump, when its above the tank like this its alot more prone to drawing air into the pipe from the hot water cylinder, idealy they should be positioned on the floor next to the hot water tank if you have enough room to do so, You can try...

if it was working for months before its unlikely to be the cylinder running out of water, espoecially after nly 2-3 mins, sounds like the pump may be drawing air into the pipe, which is why its still working on cold but not the hot. Where is the pump positioned in relation to the hot water tank?

I'd bet you have a plastic raised shower tray, rather than a stone resin one that sits on the floor. With these raised plastic shower trays there is alot of flex in them when someone is standing in it, and grout is not flexible so it may look like ts made a seal but when you stand in shower...

yes try to make sure the TRV's are fully on, take off the heads as the doc says and tap the metal pins a little incase they are jammed (unlikely though since its new system an valves) It could also be a air problem if it wasnt filled correctly, since its a sealed system youy can try turning...

more likely that when the pump comes on its sucking air down the open expansion pipe and the airs gathering in the towel rail

this would most likely be the cause yes, try tightening the nut from where the water is leeking from then top up the boiler again

It wont affect it, an place pressure reducing valve just after main stop tap no probs seco :P

here! :lol:

defo sounds like a plumber then lol :roll:

place the presure reducing valve as close to the stop tap as possible (to do whole house) or just on the feed to a individual tap if you only wanted that one reducing adding a pressure reducing valve on cold mains wont affect a shower pump, make sure you position the pump correctly though...

you can try turning off all the upstairs rads to force the water through the downstairs ones and vice versa see if it makes a differnce, what kind of system do you have?

not easy at all

bathroom towel rails are generally the place where the air accumalates as its the highest place in the crcuit, however if you are having a major air problem (you shouldnt really have to bleed it more than 2-3 times a year) then it could be the position of the pump, What speed is the pump on...
