Replacing white plastic pipe with pex...

[johnwen]

Has anyone replaced their white plastic pipe with pex?  These washboard roads on our Alaska trip are causing the retaining clamps that go around the female connector to come loose.  The rubber/plastic clamps holding them to the pvc mounting boards are coming loose as the result of the the intense shaking....the screws are stripping out and allowing the connections to loosen.  I'm surprised they didn't loosen enough to create a leak.  I just think permanent pex connectors would be a better fix.  Any reason to not replace. with pex?  I haven't studied the layout to see where all that pipe is used...water heater, pump, etc, so I expect difficulties along the way.  Just looking for a little advice now and I won't think about starting this project until stationary for a couple of weeks this winter.  Might be a good time then to do my furnace ductwork replacement/reconfiguration project :)

Thanks for all help,

John

@johnwen be careful of rigid connections to things that move or vibrate like at the water pump.

I don’t think I’ve seen any white plastic (PVC) pipe - only PEX. 
 

Where is there PVC?

Last year I found the same issue with the screws coming out of the pvc mounting boards. Service had no suggestions to offer except to replace the pvc mounting board. I don't think the pvc material is the right thing to use for this mounting board, but that's what they use. My brother and I discussed this issue and came up with a simple solution. On my Oliver (and others might vary) there is enough space below the pvc board to place a narrow strip of thin plywood -- just long and wide enough to use to sit below those locations and to reinstall some longer screws through those clamps.  I keep checking the existing clamps, and have tried adding some superglue in with the screws, and that has worked on two of them, for now.  I don't want to have to take everything out to fix this issue. I don't have the tools to cut this piece of wood, but that is my plan.

@Galileo on an Elite II Twin Bed model, it's below the curb side bed close to the stove location, where the plumbing equipment is mounted.

Look at using King StarBoard for a better waterproof mounting board. It can be cut and shaped using regular woodworking tools. I get mine from McMaster Carr but there are less expensive places to get it. A shipment from McMaster Carr usually arrives the next day depending on where you are. 
 

I think I have ordered some from TAP Plastics

I suggest using Riv-Nuts and bolt them down if you are having such a problem.

It's plastic, not pvc...by water pump, accumulator and shower.  You should have it also since you have a 2022 model :)
