I just replaced my city water regulator and some of the internal plumbing.
The components available now are the compression valves that push on to the polybutylene pipe. Problem is they still leak slightly when hooked to shore water. I have to use my water tank and pump in the meantime. Anyone know a remedy for this? Some kind of sealant to use with the compression fitting? Or a different connection altogether, and a source for these componenets.

Their fitting convert your connections to compression rather than swage as they came originally. These would hold to the max pressure of the pipe itself.

Something that may help and should always be used when hooking to unfamiliar water supplies is a pressure regulator. Mine hooks up between the hose and the coach, but some are built into the city water intake. Cost about 13 bucks.

When all else fails you can try Rectorseal thread sealant.

"When all else fails you can try Rectorseal thread sealant"
Ed's right; I use Rectorseal #5 myself. Aaand...Rectorseal is always easily removable, unlike normal "pipe dope".
More: "Teflon tape" is a joke. Pieces often come off and flow downstream plugging pipes and pump impellers - I fefuse to use it.

Plastic hardware store fittings I have used, have a threaded collar that slips over the cut end of the polybutylene tubing before you connect the fitting. The fitting itself has a tapered end with a barb, that has to be pushed firmly into the tubing before you thread the collar onto it.

Properly installed, & hand tightened firmly, these fittings won't leak as the threaded collar compresses the plastic tubing onto the taper. On fittings that are buried after they're installed, I've given them a tweak with the pliers, just to be sure, & I've always tested them before I buttoned things up.

Ordinary compression fittings that use a collar that slips over the tubing, & don't have a taper that plugs into the tubing, will leak as the soft plastic tubing compresses when they're tightened.

I'd post a picture of the kind of fitting I use if I knew how to do it, but your hardware store has a full assortment of valves, connectors, elbows, adapters, etc., to fulfill your every need.

Thanks for your helpful replies everyone.
Happy New Year!!

Jack, Olroy is right on, the only way to stop your leaks is to use the tubing inserts.

Thanks Ralph.
A trip to the hardware store is in the works
