Just wanted to say all working fine now. Had to leave system running and keep bleeding rads and other vents. Particularly the pump and then system came to life. Thanks all for your advice.

Hi johnd. Thanks for reply. I`ll leave it for a bit now and will then re-try a little later. The water that drained out of the system was clear from all rads with no discolourtion. Same when I drained down a little bit from beside the boiler in attempt to remove air lock. The F&E tank is all...

Thanks for the replies. I had to remove the radiator and its surrounding pipework that went straight into the main feed and return as we are removing the wall that its currently on. Have turned the hot water only on and tried turning speed up and down on pump but still no joy. The pump isn`t...

Hi. Hoping someone could advise on this as I`m stuck. :-( We have an open vented system with FE tank, Grundfos pump and Honeywell V4044C valve in loft and we have a Baxi Bermuda back boiler in our lounge. We live in a bungalow so only one storey. I had to drain down the system today to...

Thanks for the advice.

Hi. Quick question. Is it possible to connect 1\2" copper piping to 15mm copper piping using normal compression couplers ? Are there ones around that accomodate the different sizes on each side ? I only seem to be able to find 15mm to 15mm compression couplers. If so, are they something...

Thanks misterdubya. I was actually thinking of replacing this valve with a proper 3-way Honeywell thereby going for the Y-plan layout. Was also going to replace the programmer and then recable accordingly. Does anyone forsee any problems with doing this ? Have noticed that during...

Hi. Hoping someone could advise on this. We have what I assume is a W-Plan layout with a Honeywell V4044 1098 3\4 inch valve, grundfos pump and FE tank all in the loft. We have an old Worcester back boiler behind the fire in the lounge. Question I have is that currently when HW Only is...

Hi, Hope someone could help. Could anyone advise on the best siphon to use to replace an old Dudley Cascade S7B Siphon ? I measured the height from the base of the cistern to the top of the Cascade siphon and it measures about 270mm. On the side of the siphon is a mark that looks like...

Thanks all for the advice. I went up to the loft and found a couple of air valves not far from above the cylinder which I bled, also bled the pump again whilst off. Tested and all is fine. No gurgling\bubbling noises from the pipes and pump down to normal noise level. Thank you all.

Thanks for the advice Schmill. I'll give it a go.

Hi, Could someone advise if I would be OK to bleed air from the system when the pump is running ? Is this a safe method to get air out as it passes through the pipes ? When bleeding from the rads I only get water coming out but I can hear the gushing sound when the system first starts...

Hi kevplumb, Thanks for the reply. I think I may have forgotten to switch that over from auto when doing the draining\refilling. Doh. :-( Would this have caused air to be locked in ? In this case is there a way around getting the excess air out rather than draining down fully again ...

Hi, Hope someone can advise on this. I have an open vent system with 3-way valve and Baxi-Bermuda back boiler and live in a bungalow with only 5 rads. I have drained down the central heating system in order to get some inhibitor into the pipes (it had'nt been done in a few years). I...

Have just removed the plastic cap but there is nothing behind it.You can just see into the body of the tap. Is there anything else I can try ?

Thanks Rico. Will have a look.

Sorry. Here are the pics. Thanks

Hi, Was hoping someone could advise on this. We have a mixer tap installed in thekitchen whereby you lift and move the lever left or right for hot and copld etc.However, recently there is now a leak occurring from underneath the handle when lifting and turning it to the hot side. Would...

Hi, Would anyone be able to shed any further light on this one as I'm a bit stuck. Many thanks Barrie

Hi, We carried out the tests that were mentioned; 1) All rads have been bled again so that a trickle of water emerged. 2) The Thermostat only clicks when you turn the dial at the point when moving it from 0 - 5. After that there are no further clicks. 3) We turned the cylinder thermostat...
