freeing fozen stopcocks

[Pupp]

main stopcock on feed into house is pretty well seized and I'm wary of leaning too hard on it.... can isolate at he meter in the street easy enough so just replace (PIA due to tight access) or and tips worth trying to free off?

I hate plumbing!

It's frozen? I know it's April but it was 28 degrees here yesterday.

Seized.

I'm not a fan of stopcocks/gate valves. I much prefer lever ball valves.

A hefty spray of good ol' WD40 and rock it back and forwards should loosen it a bit at least.

Lots of WD40 and twisting the handle back and forth. This'll make it easier to turn but takes a good bit of tooing n throwing.

Isolate in street. Undo both compression nuts and replace.

Isolate in street. Remove the valve section from the body. Might be easier with a basin spanner if you've only head on access. Then replace with a new valve. Or dismantle valve and silicone grease it to bring it back to new.

Isolate water by use of stopcock and fit another stopcock in more convient place if possible.

They're the options.
