The two things that worry me about plastic a

1) Will the push-fit grippers give way and blow the joint apart (same

2) How long do those O-rings actually last? I pondered this also after I

You're not the only one to ponder that. However, you can use compression
fittings on plastic. Don't forget the sleeves though.

Interesting - I'd feel happier with that. Is that the method used to join
MDPE (have to extend a bit of the main)?
