About a year ago our main toilet started to dribble after flush had ended. I replaced a small rubber disc (can’t recall the name) and that solved that problem. Last few weeks it started to dribble again. Thought I’d deal with it another time due to lockdown etc. May be completely unrelated...

Hi Everyone I had an issue recently where my shower slowed to a trickle (bar shower mixer fed by unvented cylinder for hot and mains for cold). Plumber replaced whole shower as when dismantled it was full of limescale and a grey sludge he said he’d never seen before. New shower works great...

Looking for some guidance please. We have a wall mount shower mixer. The bar type with an on/off tap on one side and a temperature control tap on the other. For a long time the mixer tap has been stiff and only had a limited range of motion so we could never turn it to full cold or full hot...

As the title says really. Wife noticed this morning that the boiler (Vaillant) sounded like a car ticking over. After boiler went off and we left it for 10 minutes before firing it again it sounded more or less normal. It was after calling for hot water (CH had gone off) - not sure if...

Maybe not one for here but seems as good a place as any. Which will use more gas and work the boiler more: - Set CH to timed (2 hours in morning and 4 at night) Or - Set CH on constant and lower thermostat My house is new and boiler very efficient. With weather as cold as it is the...

We have a Valliant (is that how you spell it?) combi boiler in a new(ish) build house. No problems as such but want to check whether the noises I hear are normal. Boiler is located in a cupboard in the attic. House is barely a year old and we have lived here a few months. Just started...

Potterton Promax HE boiler started making a noise which sounds like a whistling noise for about 1 to 2 minutes after firing. Everything is working fine but just wondered if it might be anything to worry about. Thanks

I have the above boiler and my pump is on its last legs. My plumber has let me down and can't change the pump this week. If the pump fails while running am I right go thinking my boiler will realise there is no water flow and cut out?

My central heating pump is knackered (horrible knocking rumbling noise when running). Any way - plumber is booked and is coming out later this week to change it. In the meantime however I have noticed that my radiators seem to be getting much hotter than usual and one in particular (the first...

Noticed recently that the pump for my CH/DHW has started making a rumbling noise when running. It is not constant and not all the time but is quite audible when happening. Is this something to worry about before winter starts or just some air in it or something? Don't want it to pack up...

My boiler (Potterton Promax HE) and heating system in general has had so many problems I think I sometimes think the worst. I have noticed some behaviour which may be perfectly normal and I just haven't noticed before but may be abnormal so though worth checking. When the CH is on it runs...

I noticed last night that the energy bulb at the top of the stairs in my house flickers (or rather flashes) every few seconds. Not a bright flash - it was very very faint and didn't light the whole bulb, and unless I had been stood right under it in the dark looking in that general direction I...

I have a Potterton Promax HE system with 3 rads downstairs and 4 upstairs. The bathroom and bottom of stairs are the first to get hot when the heating is on. For a while now I have noticed that there seems to be a lot of air in the system - there is an air/water noise through the pump when...

As of today, my (troublesome) Potterton boiler has started not firing of it's own accord (sometimes at least). The pump and 3 port valve do their stuff, but no ignition. However, if I press the reset button on the front, it fires immediately. When it did it, the DHW was on as well as the...

A couple of weeks ago we had the CH on to dry some clothes and the electricity in the house tripped. Didn't think anything of it and put it back on. No problems. Today it was raining, and I needed to dry some stuff I didn't want to put though the tumble dryer, so I put the heating on again...

My central heating system doesn't have a built in frost protection system. Last winter, we simply put the heating on constant and at night or when we went out turned the stat down to about 10C so it would come on if it got really cold to prevent frost. This winter however, we have decided...

For reference the boiler is a condensing Potterton Promax HE (with Potterton thermostat and programmer). System is about 3-4 years old and was put in by the house builders I assume. I also know VERY little about how central heating/boilers etc. work. The last week or so we have been using...

Our bath has always had a slight creak to it when moving around showering. However, we had some damaged sealant on the edge which I replaced, and so as not to get it too wet for a few days I have been standing at the opposite end of the bath to shower than I normally do for the last couple of...

Bath sprung a leak this morning where the sealant has got damaged (scrubbed too hard cleaning it!). Manifested itself with a wet ceiling below! Took the side off the bath and it's definately from the area which I suspected. Been out and bought some new sealant and will apply it tonight...

Recently noticed a really foul egg smell from the bathroom sink after washing hands in it or brushing teeth etc. Poured bleach down and the smell goes for a few days but then returns. Also tried running loads of hot water down it and that has the same effect - smell goes for a few days but...
