If the connection is a supply line, the tolerance has to be tight. But if you need to do it on a large diameter drain pipe, just take more material from the inside of the coupling. The PVC cement will close gaps on drain pipes well enough.pugboy wrote:how you sliding them fittings ?
with grease ?
i find bigger fittings does give real trouble to slide on
they bind a lot.adnj wrote:In general, a 4×90° circuit adds a good amount of flow friction.
What we do if you are patching a short section of PVC pipe:
- file the center lands from two couplings until they will slide over the pipe.
- place one coupling on either side of the patch.
- cut the pipe patch to the exact length between the pipe ends
- mark the pipe to show where the couplings should be when installed.
- add cement to all pipe ends and slide the couplings into place from either side.
Sometimes you can get away with only filing one coupling and install the other as you normally would.

it may work with hand tight but can leak eventually and threads should be clean, no mud or will give trouble to tighten.Gladiator wrote:Spann... That's actually a very bad technique. Use a union please. All them elbow will just restrict flow...rspann wrote:jason-79 ,good technique .

Asking because hardwares selling cement and blocks and other material apart from electrical and plumbing as usual.
