can you just replace a valve lever?

[giveitawhirl]

Hello, I have a leak from the quarter-turn isolation valve lever for the central heating flow connection. The leak was coming the connection so I put some tape round to see if that stopped the drip. It has but there is now coming from the screw that attaches the lever to the fitting. Replacement of that particular fitting is going to be involved as it is attached to the tap rail of the boiler. Is it feasible to get another plastic lever and just replace if so are they standard fit or different according to manufacturer? If not is there some temporary measure to bung/stop the drip? Thanks.

Please post a photo: I cannot understand what you mean, I'm afraid.

It's still leaking from the same place.
The tape is diverting it.
Suggest you dry it off carefully and find out exactly where the water is coming from and post a pic showing this.

I dried it and spent a while looking before adding the tape. At the top of that plastic lever is the source, between the thread at the top that the tape covers. I believe it was coming form the screw then too but that is the lowest point where the water collects and drips from so hard. to say for definite.

Yep and that is the part. No workaround/temporary measure possible? Would the fix go as below?
1. Isolate cold water inlet and CH return
2. Drain system from radiator on ground floor
3. Open bleed valve upstairs to allow pressure to empty
4. Drain boiler from white tap?
5. Access via side panel to unscrew part
6. Get wet - how much will come out?
7. Need to clean existing threads to remove lime/ensure good fit?
8. Fit the new tap using PFTE and paste to minimise potential leaks
9. Make sure CH/radiators ready to be filled (closed off from draining), also boiler drain
10. Turn-on cold water inlet and CH return (and new CH flow)
11. Pressurise system to 1.5 bar
12. If leaking repeat steps until no leaks
