The blow out port for our in ground sprinklers slowly drips every 5-10 seconds. Pictures of the port here: https://imgur.com/a/vur2os2
How can I stop the drip? I have a few ideas, but I’m not sure which would be the best:
Teflon tape. I’m pretty sure this is a PVC connection and teflon tape seems like it should work. This port is opened up every Fall to blowout the sprinklers, so the tape might need to be replaced each year too? Also, I’ve read that putting teflon tape can make the connection too thick and possibly crack it.
New stopper-plug-thing. Would replacing the screw in connector possibly work? Also, what is the the correct name for this part? I suspect stopper-plug-thing isn’t quite right.
Rubber washer of some type?
