Thanks for the reply. I have bought the following: Myson 2-Way TRV http://www.heatingcontrolsonline.co.uk/radiator-valves-c-28.html/thermostatic-radiator-valves-c-28_37.html/myson-trv-way-trv-p-362.html 15-10mm Reducer...

I have a leaking Myson One-Way TRV on a radiator that is leaking from the pin fairly consistently, so I am planning to replace it. This is probably the most advanced bit of plumbing I will have attempted to just wanted to get some advice from more sage members. 1 - I am replacing it with a...

Yeah the arrow is pointing away from it, and having had a really good butchers at it last night I am quite convinced it's pumping the wrong way. Is there an easy way to reverse the flow direction? The pump is in quite a tight space and I don't think it would fit if I just rotated it 180...

Pics below, yes it's usual airing cupboard and cylinder. Close-up of pump Hot water cylinder and pipes Pipes, pump and acctuator

The pump can really only go in one way (it's installed horizontally and it's the same orientation as the old one). I'm no expert but there are about three pipes coming off the hot water cylinder - I will check for the arrow on the pump and make sure it's pointing towards then. There's...

Hi all, We had a new replacement Grundfos pump (Grundfos 15-90N) installed late last year. Shortly after, the TRVs on all the rads (although only one at a time) started making a really loud banging/whining/clunking sound when starting to reach temperature. The valves are Myson One-Way TRVs...

Thanks for the feedback. Sorry if I'm being a bit dense, but if air is leaving the system through the separator (the stream of bubbles from the expansion tank), how does a blocked separator bring in more air? Is it actually sucking air down the expansion pipe due to turbulence or...

The pump model is a Grundfos UPS 15-60 130, set at II out of III. Checked the expansion pipe going into the header tank and it wasn't sucking water when I put a cup under it (the pipe was also stone cold at the top, but hot near the hot water tank, but I assume that's normal). Had a look...

Just away to leave work, but I think the pump it set to speed III - i.e. the highest. Might be worth lowering it I suppose?

I'm a bit of a noob when it comes to all this, so please bear with me :) Recently had the pump replaced in the CH system (Grundfos 15-90N I think) and since then, there is a decent amount of air trapped in the system - you can hear it swooshing through the boiler and especially at the pump...

I think it's about 2 years old. It appears to have shattered after the extremely bad winter we had last year. The only reason I can think of, is that the previous owners of the house re-sealed it themselves and possibly got some moisture trapped between the sealant and the concrete. It's not...

Yes I have spoken to a few. The original contractor said a section would need to be taken out and completely redone. Another one said they could try patching it up (for considerably less money). I'm thinking replacing it might just be the best option.

After last winter, there's several areas on the surface of the driveway that's shattered. About 90% of the rest of the driveway is in perfect nick. I'm a bit stumped as to what to do - I've had some guys say I should have the area where there's been damage replaced (i.e. cut out and...
