I have 1989 Manufactured home and am replacing all fixtures and floor in guest bath. I noticed the gray poly piping and fixtures and decided to changeout to pex 1/2 inch.
I had to replace two poly t fittings with the new pex copper ones and all 3 connections on each fitting passed the go and no-go test.
On each of them, I had a 4 foot leg (one for toilet) (one for sink) in which I turned the pipe a little and I noticed the pex crimp ring move on the fixture a little. I find these pex pipes are somewhat hard to work on without moving at the fitting that has been crimped (maybe I am doing backwards).
At any rate, concerned I should tear out the t' fittings and redo. I did turn on water and did NOT see any leaking. I just get very paranoid about these things.
Questions - should i redo the t, and if so, could I consider the newer brass push in type connectors as these seem reliable and easier to work with?
How do I finish off the toilet connector, is there a special fitting I must use to provide firmness prior to installing the shutoff valve?
