Moved into an new house, 13 year old ex rental which has been neglected a bit.
Couple of questions:
The filling loop on the vented tank has been fitted with a braided hose that is so tight it has to be unravelled to allow water to pass, so I've bought a longer one that can loop naturally without kinking.
Is it as simple as keeping both valves closed either side of the hose and swap it out??
Also, I noticed the water pressure to the house is poor. I used to live in same street and the pressure there was great. This house is at the end of a row of 4 townhouses. It has its own meter and stop cock, is there any min level of pressure I should get?
I can't get any more than 1 bar into the vessel on the vented tank, is that because there's only that amount coming into property?
Last one, on the first floor there's a thermostat on the wall which feeds back to the two channel timer at the boiler.
I have a Curv wireless stat and looking to site the receiver. Normally I'd fit a 5 core to the boiler (combi) but on this occasion that's looking like that's an absolute ball ache.
The feed coming into the dial thermostat has the pair for the switch and a live feed. There's also one other wire not connected, could that be a neatral?
Could I fit this using the live feed only??
Yes.
Don't know. Check stop cock fully open. Check stop cock on road side too. Get a tap pressure gauge.
Probably
You should be able to test if it's the neutral. I hate to do the if you don't know answer, but figuring out of something is the neutral is pretty basic and also safety critical. RCD should save you mind you.
Maybe depends on the wiring of the system.
Sorry, I’m gonna go full on elf and safety with you 🙂
Vented tanks don’t have filling loops.
It sounds like you’re describing an unvented cylinder? If that is the case then I’d seriously encourage you to get a correctly certified heating engineer round to service the system and give it the once over if it has been neglected. Unvented systems must be serviced annually by a G3 certified plumber. This is to prevent them exploding and blowing your house to bits. Shouldn’t cost a fortune for a service and check.
You might on the other hand be describing a small wee expansion vessel tank with a filling loop for a combi boiler?
It might not be pressurising for a number of reasons. Figure out what system you’ve got and get a plumber in to service it. If it is unvented ensure they have G3 cert.
