'02 Journey bathroom remodel...

[LandOGil]

Pex is expandable with the proper tool. Most plumbers will have the tool to expand and will have the additional parts needed when the valve is cut out and replaced

Those are holding tanks on mine.. i needed to get in there to run a pair of 4Ga cables from the battery to solar charger.
To the Pex.. you will find out quickly that you cant get a Pex/ PVC cutter through that hole with enough space to open the jaws and cut. I went to HD and bought a single action plastic Husky cutter and cut the handles WAY down to accomplish the deed. You’ll likely leave some blood behind but it can be done.. i used a SharkBite splice and (knocking on wood..) its been solid for several years

Yah, I was wondering if I will be able to get a PEX cutting tool in that hole.

You used a Husky cutter? Is that like the cutter that Home Depot is carrying these days for $8?

And you cut the handles off on the tool so you could fit the cutter in the hole in the shower wall if I understand correctly?

Where you able to get some slack by pulling on the pipes, and if so, how much?

I have used shark bite fittings and also regular pex crimp as there is a compact pex crisper available. The flair it fittings are such a pain in the butt.
I also added another round heater vent to my shower pan on my 36 G to give me easier access when I was redoing my my shower p trap.

Here's a recent thread regarding a shower leak in a 2002 Adventurer 35U that may have some applicability to your situation. Post #8 (vetman90) gives details on removing the shower surround and base, giving access to the plumbing. It mentions that the lines are secured to the floor, thereby eliminating the possibility of using the old lines to "fish" the new ones in:

With a stretched arm I should be able to reach the pipes under the pantry and that's my next move...to see if they are attached to the floor or if they are loose enough to give me a bit of slack.

OK, checked the pipes and sure enough, they are attached to the floor. So there's no slack. When I pull the pantry panels out, perhaps I'll be able to access the pipes.

Today is a travel day, heading south to Yuma for warmer weather so I'll not be working on this for a while.

Thanks for all the help.

Three little words "Pressure Surge Tank"

That shower valve is a tough one to access. I have found several plumbing connections over the years in my coach that are next to impossible to get to, now that the coach is fully assembled.

To get to the pipes to splice new connections to the shower valve, I might cut an access hole below the current opening. Then it will be easy to access the pipes, do all you need to do. Then get a thin sheet of plastic, and screw & caulk it into place. Done right, you will be the only one that ever notices it. Just an idea.

Three more little words...I have one.

I'm doing the remodeling to create the worlds best temp regulated shower in an RV. Suited, I'd image, only for me.
