Hi All ;
I think I'm all set to replace my water softener - tomorrow.
Any tips or tricks are appreciated - I'm more of a WanneBe -
than a bona fide DIY'er.
I'm new to the shark-bite and pex plumbing - seems simple -
- I've checked a few web sites & Utube videos .. any advice is
appreciated.
Existing is 3/4 inch copper with single handle brass bypass valve.
Replacement is 3/4 inch but plastic bypass with two plastic "valves".

Q1 : screwing the 3/4 shark onto the plastic bypass -
- a few wraps of teflon and snug it up good ?
- special cement ? brass - to - plastic ?

Q2 : cutting pex without a proper tool ?
- heavy razor knife and care to keep square ?

Thanks in advance.
John T.
