Cut valve connections to the correct ceiling height

Hello everyone,

how did you cut your valve connections to the correct height?

Saw blade, reciprocating saw??
And do you stay slightly below the finished ceiling height (when plasterboard is mounted on the ceiling)?

Thank you

Hi,

with the angle grinder and _BEFORE_ installation. They should be about 2 mm shorter than the finished ceiling. So that the valve really rests against the ceiling.

If the connections are already installed, it's a bit difficult. A multi-cutter works, but it's tricky and will cost you some saw blades.

Best regards,

Hello Andreas,

ok, the connections have all been installed for a long time. Since I am suspending the ceilings in all but 2 rooms and am about to start boarding with gypsum, it seems the shortening will still work. And even where the ceiling is not suspended, it is to be fully spackled, so the 2mm should definitely be easily achievable there as well. So I will cut off the outlets soon. If I do it with the angle grinder, I have to cover the relevant windows, otherwise I'm afraid something might get damaged. That's why I thought a reciprocating saw would be the smarter alternative.

Thanks for your answer

Hi,
I have a similar problem, with three wall outlets I forgot to cut them to the right length before plastering. They are now still at the "approximately fitting" length, meaning 15-20 mm too long.
I wouldn't want to use an angle grinder in the apartment if I can avoid it somehow. The sparks are sometimes bigger and glow longer. You can quickly burn a hole in a ceiling that is supposed to protect your window. If anything, I would at least wet the ceiling beforehand.

Best regards,

I think with us it was done with a Dremel (or something similar, in any case a small cutting disc on it). Since the pipes are made of plastic, there are no sparks. And it was done at the very end, the pipes are closed, so no dust gets in during the construction phase.

What systems do you have?

The valve connections are basically a metal pipe at the bottom that protrudes through the ceiling from above. It has a wall thickness of 1-1.5 mm, so a small Dremel is somewhat overwhelmed there... ;-)

Best regards,
