djrussell I dont know what the codes are for your area but in mine when I first started useing sharkbite they were neither allowed or dis allowed i guess they were waiting for more testing ? but I used them anyway now they are approved so I have had them in for over 4 years now and a couple are transitioned from copper I have had to move several a few times due to reconfigrations( wife wants thing different after I get half way done go figure) any way I have had zero leaks even in the coldest of winter so dont be worried about useing them I love em if they are allowed in your area just make sure you get the pex all the way in
thanks for the extra advice. i just talked with the plumbing inspector about a few things. i got his cell number. cool.
sharkbite fittings aren't allowed behind walls in my county. cpvc or pex fittings need to be brass. no plastic fittings behind walls either. i'm also relieved to find out that i don't need a permit to do this. the ordinances read like i would but not so. if i'm changing from a tub to shower though, he recommended pulling one though since the drain size is different. tubs are 1-1/2" (what's in there now), showers are 2". i can glue some ABS together though and slope it just fine so i'll probably skip that inspection.
so it looks like i'll need to get some transition fittings sweated on. what would you all say is a fair price for a plumber to do that? i have a feeling that after the "trip charge" i might as well just do it myself. and if that's the case, i'll just do the rest in copper too.
