    You have to take down the false wall/bulkhead in the pass-through storage. You'll note there are minimal screws holding up the carpeted panels, and many of us end up doing mods to make access even faster.

    Why? Is your water not hot enough? If so, check that the outside faucet is actually turned off first by the handle valves to see if it solves it (common oops).

    Yes, itís maybe half of the cold water pressure and thatís being generous. I have cleaned hot water tank, checked those handles, drained low points and checked pressure running on board pump. Iím thinking check valve cause it was good.

    Sounds like you're on top of it. The RV style checks are very light duty poppet-type, with the Valterra probably being the best in that space to replace the plastic one yours likely has from the factory. If you have a plumbing supply near you, LF600 Maxi-Flo check is a nice, reliable upgrade too.

    Yep, 1/2" NPT and male threads either end. So if you get an LF600 you'll need some short pipe nipples as the threads are female.
