I have a Momentum 381M and I'm staring to look into being able to hook up my Pressure Washer.

It's electric, I know I'm good to power it with my Generator (I wouldn't be using it in parks where I have 50A service). But I'm curious as to hooking up the water side of it.

My pressure washer has it's own pump built in, so really all I need is a supply line from my water tank but I can't have the supply operated from the internal RV water pump.
From what I've noticed so far, the only current hookup would be from the factory outdoor shower connection which is some type of quick disconnect and fairly small hose so I'm not even sure that would work.

I'm thinking worst case is I could maybe tap the tank and add an aux line, I just need the water to gravity feed. Ideally I need a typical water hose connection to connect directly to my pressure washer.
My specific pressure washer operates at about 2 GPM for what it's worth.


I'm sure someone out there has connected a pressure washer to their RV before Hoping one of you has some insight to this, thanks!
