Some advice on two different problems please?

[tamz]

is your cold water inlet the first pipe on the flow before the pump? the second one being 22mm and going over the cistern?

Probably is Fuzzy, in which case the neutral point being the feed will mean it will draw air.
Easiest fix is change it to a feed expansion.

Whoever fitted this lot has never even slept with a plumber but is about the usual quality for landlord accommodation. Surprised at the Worcs boiler tho. That is a first. Usually a Ravenheap

 

[fuzzy]

you mean link them ?? yeh seen that doen before and does fix the problem but not ideal. bit more difficult to change to a VIP

Hey guys, I think I need another few morning to monitor this to be sure this is not a fluke, but this morning it didn't knock. It was quiet as anything. Well...just the pump noise with no air knocks. Maybe when I turned the bypass valve the other way this time it shut it off properly and it wasn't fully closed last time? Maybe to do with it leaking when I turn it not sealing properly? I will let you know what tomorrow is like
If this does turn out to fix it, I don't know how to thank you all. Seriously thanks so much.

The thermostat thing I can live with since the heating does work I guess.

Someone earlier said that the plumber didn't like clips (or did can't remember), what does that refer to in the pics? I know the work looks shoddy you say, would this have been done when the house was first built or recently? Is the Worcs boiler a goodun then? Thanks again all. Really appreciate it.

is your thermostat sited above a radiator or any heat source?

 

[fuzzy]

room stat he is asking mate

No, this is why it was moved in the first place since it was in a corner in the lounge near to a radiator. It got moved upstairs on the landing not near any heat or cold source.

 

[fuzzy]

landing isnt a great place as heat rises. best place is the hall, shouldnt give you the probs you are usggesting though, when does it 'click'?

 

[coursemyhorse]

If I turn it on first thing in the morning in this current weather (starting to get colder) I gradually turn it and it will click on at around 25/26 c

I think the knocking may have gone away! Touch wood.

 

[fuzzy]

if it is clicking at 25/26c then it suggest your house is around that temp, thats hot!!!!!!!!!!!!!!! is it hot? if not then the stat itself could be the problem
