I know CH copper pipes that run in unoccupied areas,loft/roofspace cellars etc should be lagged but I'm not sure if pipes that run under groundfloor floorboards should be. The floor is suspended about 3' above the ground so I would have thought the pipework would suffer heat loss. On the other...

Fitted the g+b wire to the terminal Marked L and it seems to work although the pumps bearing have failed so it's not very efficient and not draining sufficiently to allow machine to go to fast spin speed. Machines a pain to to pull out but I've ordered a new pump so when that arrives I will...

Just removed wiring from drain pump [red and green + black wire] on my hoover quattro system 1300 washing machine and I was sure the green + black wire went to the terminal marked L and the red to N but surely red is usually live and should go to L and green + black to N. Can someone please...

Not sure exactly why a minimum of 450mm maybe Steve can enlighten you, mine now measures 410mm after reconfiguration today, no air's entering the HW so I'm :D Thanks for the advice.

Thanks for the input ChrisR and Gplumb but would it be better to do as Steve has recommended particularly the 450mm offset to avoid heat being lost through the vent. It's not to much trouble to change layout and I would prefer to achieve as near as possible to the optimum set up.

Thanks again Steve, if I go straight to the vertical it only measures 270mm so will it be ok to put in a 90 degree bend to gain the extra length required. Yes I did buy a 3/4" to 22mm fitting for the pump pipe

Thanks Steve would this be ok

Thats what I thought might be happening, here's a photo as picture isn't clear. Any suggestions how i could rectify my mistake[img]

Two days ago I installed 140 l indirect cylinder and 50 gallon loft tank, since installed I them I have a small amount of air coming out of the HW taps. The only differences from the old system are the increased size of the tanks, a surrey flange (ready for shower pump with valve closed) and...

Cheers Simond, . Have you known the relays to failbefore beause I was thinking there may be a fault elsewhere thats causing the relays to buzz although saying that the noise stops after a while. Not 100% sure what a 2 channel programme is could you please clarify.

My CH programmer honeywell ST1700, has started to make a buzzing sound when he hot water comes on. I noticed there are 2 black components that look like relays which I think may be the source of the noise. Is it possible to replace the relays or will I have to buy a new programmer, if a new...

My washing machine hoover quarttro system 1300 ws136 will not reach full spin speed when it gets to n# 7 it just spins at slow spin speed or doesn't spin at all anyone have any idea's what maybe causing this.

Bathroom stripped out ready for boarding, decided to use aquapanel in the wet areas around bath and shower enclosure and plasterboard for the rest. I plan to tape the joints and fill them with plasterboard adhesive but unsure what to do around window recess will the same approach be ok. A couple...

My boiler Ideal mexico super 2 approx 16 years old has started to kettle over the last couple of weeks. I know the kettling is caused by scale build up in the heat exchanger and is introducing air into the system so I plan to drain down the system then refill using fernox F3 run it for a week...

maybe but even if it is temporary the bottles have almost been squashed flat by the weight, surely there must of been some thing more solid knocking about. As an engineer myself there are some things you don't do no matter how temporary, but everyone has different standards.
