Yes about that depth poss 2mm here and there

It’s new about a week ago and kept air tight. The walls were all given a mist coat then a normal strength undercoat. I feel it must be the type of paint that was originally on the wall that’s not letting it stick

Just to add. Today I removed the old filler in places and keyed the surface and re filled - this evening there are small blisters again on the surface which suggest it’s not going to stick

Painting the house and in several rooms where I’ve used filler - once sanded down when I come to undercoat the filler is lifting off on the roller ... could the previous paint be an oil based paint or not? if so is the solution to coat the wall with one of the Zinsser products and if so which...

Ian, how straightforward Or otherwise is testing the Cylinder thermostat ? Be good to know if that’s causing the problem or whether it is as you suggest possibly the controller ?

You're absolutely right. Im tearing what little hair I have left, out ...

it'll heat the water until the boilers sorted ....

Hello again Ian, so not the dreaded PCB thankfully. Im just connecting up the immersion heater now so that should eliminate the Cylinder thermostat from the equation ?

I have a Potterton Suprima 80, which has of yesterday not firing up for the call for HW from the programmer. The zone valves (Honeywell V4043H) as a complete unit were replaced a couple of weeks back and were functioning as expected when tested with both the HW and CH circuits. When calling for...

Having read a bit more Ive come across whats been described as 'Gravity Flow' which to stop this there is a check valve on the radiator loop - am I going off in the wrong direction with this line of thought. I have some pics of the pipework immediately above the boiler which may make sense to...

Thanks again Ian, recently was informed that the pump had been plumbed in on the return circuit rather than the flow, after posting pics here for another issue so would that be exasperating the issue ?

Great, many thanks

Hello, any recommendations on where I can readily get a length of 150mm white guttering Im in Surrey but willing to collect, only need 2.4m but respect it may well be a standard 4m length. Thanks

Ian, am i right in thinking that if the rads are heating up then the heating of the hot water in the cylinder is being compromised or does it continue to heat the water and the warming of the rads is an unwanted side effect - basically am I getting less hot water than I should ? Thanks

Ian, I'll have a look and see if I can decipher the pipework above the boiler- thank you

Hi, wondering if anyone can shed any light on the following; I have recently replaced both zone valves (Honeywell V4043H) models as complete units hoping to eradicate the issue of the heating circuit warming up when the HW circuit is the only one selected. However the issue still persists. It...

its 3 feet exactly

Hi, the top of the coil is approx 3-4 feet below the bottom of the F&E tank, I can measure it to be certain tho. Thanks

Having had the hot water cylinder recently relocated to the loft the following is now occurring - There's a continuous gurgling and sloshing of water in the flow and return pipes and pump when the boiler fires for the HW circuit so clearly its sucking in through the expansion pipe i assume...

Hi Terry/anyone with a thought ... Wondering if I can call on your experience once again - There is now a pretty continuous gurgling and sloshing of water in the flow and return pipes and pump when the boiler fires for the HW circuit. Its definitely air. Ive connected a hose to the drain point...
