Rad valve replacement checklist

[ShaunCorbs]

Yep that's the one, I thought it was blue instead of white.

So turn the stopcock off, connect hose to rad, open fill loop, open bleed valves, drain system.

Fit new fill loop, fit new valve, close drain off, close bleed valves, stopcock on, check fill loop and fill, bleed, fill, bleed etc.

Once I'm sure everything is ok, close both valves to a rad and drain some water out and buy or make something to add inhibitor. I haven't found a good way to add inhibitor yet.

Thanks for your time on this Shaun (and everyone!) it really helps.

yes thats it

Stuff like this always makes me smile. 20 quid on petrol, plus the cost of the wrong stuff, hours of time, house needing redecorated and the wife probably not speaking........all to save paying a pro who would have had it done before you boiled the kettle.
How hard can it be lol.

Right, the new valve is on and fill loop is replaced. System is up to 1 bar with nothing but water coming out of any rad. Don't want to jinx it but so far so good.

If everything is still fine tomorrow and there's no leaks or drop in pressure I'll add the inhibitor.

The thing that really screwed me over was the m******f****** b**** of an olive on that microbore. Took a while to work out a strategy to get it off without damaging the delicate pipe. (It was 10mm btw). I'd like to replace quite a few of the valves around the house but I'll have to find some with the same thread because I can't be going through getting all the olives off! 🙂

You say that but I've learnt a lot these past few days and would be comfortable having a go at doing a bathroom for example which I wouldn't have before. I also understand how my heating system works now when previously it was a bit of a vague blur.

Screwfix is not even half a mile from my house and I'd pop in there on the way back from somewhere. The stuff that wasn't suitable was returned and I now own some grips and 3 adjustable spanners I didn't have before.

What would you quote for going out to someone's place, draining down, replacing a rad valve and fill loop?

Lol. Take the old valve into a plumbers merchants and see what they have. Try the nut on the old valve. There are about 3 different sizes of 10mm fitting threads depending on the manu.

BTw start in PTS cos that old valve looks like a pts tradesave one.

Good advice, thanks!

£80 quid cash inc materials (if i liked you) and you were local and it would have taken longer to find the valve in the van than it would have to do the job.

Plumbing like most things isn't really hard to do especially these days but knowing what to do and having the right gear kinda gives you the edge 😉

Looks like an old tradesave valve. Might have an 8 x 10mm bullet in it.

I now understand what this comment means 😉

Yer learning lol

£80 inc parts
(As long as they're on the van and I've been keeping it tidy enough to get to them)

I like that your positive about learning something, I would let you watch tho 🙂
