Flex PVC too small for fittings
I received the following inquiry via email:
I really enjoyed reading about your sprinkler system, so I decided to give it a shot. I have 2 issues. First, The flexible pvc pipe fits loosely in the pvc couplings and joints. Did you experience this?
I haven’t noticed any issue with the flex PVC fitting in the couplings/joints I’ve used. (You should be able to get a good feel for how tightly my joints made up by watching the example video in the article.) If you are sure the sizes match, then I suggest taking a sample to the hardware store where you bought the components to see if they can offer an explanation.
Also, the spigot pvc fittings detach when completely screwed in to the spigot The little joint pops out and separates from the spinning head. Has this happened to you? Over all any advice you offer on pvc cementing the pipe into the fittings would be appreciated.
I’ve never had that issue, either. Could it be you’re screwing in the fittings too far? They shouldn’t have to go on very tight to make a good seal on the washer.
As a side note, I’ve had issues with the spigot PVC fittings leaking from time to time. Usually, however, as long as the leak is very small (i.e., doesn’t affect the pressure so much as to compromise the sprinkler coverage and doesn’t cause my gut pain from any waste), I let it ride.
I hope you’ll come back and reply here if you find out anything useful in your search. Good luck!
RE: Flex PVC too small for fittings by Anonymous
It could be.. Today’s debacle was making a 5 foot extension line out of flex pvc. I used a femael to male pvc end with a spigot connector, and a standard garden hose adapter on the other end. Under full pressure, the hose last 20 hours. My ends stood up quite well though.
I have decided to give all the fittings ample time to dry, and through the design realize the system will never be under that great of pressure (especially with the drain fitting).
Anyhoo, thank you for the info!
