Microlite 25BRDS - faucet question not specific to model.

[benchmarks]

I am looking to purchase a new kitchen faucet, but it is very tight quarters under the sink in order to try and do it. Any tips? The other thing that makes me nervous is the lines are pex tubing. Any way to change out without buying special tools? Other?

The PEX lines connect to the faucet just as they would in a sticks and bricks home. No need for worry when installing a replacement unless your replacement is radically different than the original. That mod is one most folks do regularly.

Most of the better kitchen faucets come with 3/8” supply lines already connected at the valve body. Most faucets in RVs have 1/2” posts that have been connected to with 1/2” PEX and a 1/2” swivel nut with a washer inside of it. If you get a new faucet with 1/2” posts to connect to, it wil be a simple swap-out. If you get a new faucet with the supply lines already attached, just buy a couple of push-on 1/2”x3/8” stops/shutoffs. Cut the PEX, plush the new shutoff onto it and then connect the faucet’s 3/8” compression end to the shutoff. Using shutoffs instead of just reducing couplings will cost a little bit more, but having shutoffs for the kitchen faucet will be handy. No special tools will be required for this — cut the PEX with a razor blade or copper tube cutters (if you have one) unless you want to buy an inexpensive cutting tool for PEX/CPVC.

You may have to cut the pex to install the new faucet. I dont' have any advice on the faucet replacement itself but I can tell you that the clamp placement on pex is more critical that other types of hose or pipe that uses clamps. The best clamping system are the copper rings with the accompanying pliers to perfom the crimps, also the more expensive route but you are paying more for the best process. The second best is the stainless steel clamps and the proper pliers to crimp them (not as expensive and you can use the pliers on your automotive ss crimp clamps). Some will say to skip the pliers for the ss clamps and just use side cutters or nippers but then you will not get a good crimp and it will probably leak.

I replaced the faucet in my 2020 25BRDS recently...much easier access to the area by removing the control panel with tank indicators & light switches. Not sure if your 2018 is setup the same way.
