sorry should have said that hot water still heats up, but central heating flow pipe gets hot straight away little or no heat to radiators when central heating is on.

standard 105e. switched to hot water only, and boiler was cold. the boiler belongs to a friend and we were dicussing how best to flush the system when I tried turning on the hot tap. iwas sure I'd read that this would indicate a fault on the diverter valve that's why i asked. from hi-specs...

radiators were not heating up. suspected sludge build up. however turned hot tap on and central heating flow pipe got red hot. could this be a diverter valve problem .the boiler is a Baxi 105e. thanks.

Thanks for the reply. will be replacing existing clapped out shower so i suppose the distances from tank to shower are o.k existing shower has given good performance over sixten years. have looked at screwfix web site and was baffled by the different types. manual mixer, thermostatic mixer and...

Hi all. looking for a mixer shower to run off a gravity system, no pump. what sort of features should i be looking for? is there any noteable difference between the exposecd valve showers and the bar mixers? Thanks in anticipation.

just thought i'd give an update to this. a new identical valve was aquired and the new head used to replace the chattering one. the noise still persists. depressing the pin with the head removed causes a clunking noise and sometimes the chattering noise can also be duplicated. i guess this means...

drayton web site says "reverse flow capability". i take it this means bi-directional?

thanks for replies. according to drayton web site these can be fitted on flow or return. they belong to a friend who was justgoing to get a replacement head but I thought i'd ask here first. thanks again.

Could someone please advise the cause of this problem. Drayton RT111 trv, one of three fitted back in january. is it just duff or could something else be causing it? thanks.

thank you for that info gas guru. i've had the valve out and cleaned the washer and it's seat but it still lets water through so i guess it's time for a new valve or washer. incidentally we tried the helpline number on the instruction booklet and they could only help us if we could give them the...

sorry can't post a pic but we have an instruction manual that i have scanned and uploaded to photo bucket. will try to link to it. definitely not the ball valve cos we can lift that to shut it off.

my niece has a problem with water constantly running into her toilet bowl.. the toilet has a "siamp single flush valve" which we cannot seem to obtain locally. would another type of flushing valve be suitable or must we stay with a "siamp"? thanks in anticipation.

If I was to get an electrician to do all the necessary work up to the positiooin of the shower isiolating swittch, would i then be able to make the final connection to the shower unit at a later date?

Thanks for that info doyle. The BG guy dismissed using cement as it could corrode the pipes, so I am guessing that they aren't sleeved. I haven't been round to look yet am going later today. Thanks.

Hi all. My parents have a back boiler on a BG service contract. For years the service engineers pointed out that the vent in the floor was too small. This year we corrected the problem in time for their visit. This year they have crabbed the fact that the pipes through the wall from the boiler...

We have a bath/shower mixer, one where the handset rests on a cradle. over the past month, when having a shower the temperature has been too hot to bear. it appears as if more hot water than cold is getting to the shower head. When on the bath filling setting, the cold water easily overpowers...

Thanks for the reply. Will have a look today re: cap and hole. Can't raise water levevel anymore as it is on the required mark and almost over the top of the siphon.

A female aquaintance is having problems with her toilet not flushing properly. The siphon has been replaced twice in recent months by a local plumber but when flushed the cistern only half empties. The cistern is marked as having a 7.5ltr capacity. The top of the siphon is level with the mark on...

Thanks for the reply. I'll pass the info on.

On a system heated by gravity flow from a back boiler what sort of temperature would you expect the hot water to reach. The hot water storage in question is an Elson tank with no thermostat other than what is on the boiler. We measured the HW temp today and it was only 53 degrees. I'm enquiring...
