Seems like it. Except in my case its rewiring some lights.

Now it's all back together and leak-free, but seems to have trouble
with the flush itself - the syphon doesn't stop syphoning. My
suspicion is that the fast-filling Fluidmaster simply starts to re-
fill the cistern before it's fully emptied and breaks the syphon.
After all, Delchem's design is based around a flapper valve rather
than a syphon. Is there anything I can do to regulate this? At present
I've just left the supply ball valve at 45o, which isn't quite ideal.

Could you install a service valve on the supply & leave it partly closed to
reduce the incoming flow?
