I've got a new 5th Wheel. The bathroom shower head is about 10' above ground level. I use a 40psi pressure reducer that is attached to the end of the hose, just before it enters the camper. I've always used these on my campers. Problem is, with this reducer, the water pressure is not enough to push a good stream thru the shower head. Does everyone use these pressure reducers?Any thoughts on long term use without the reducer?

If you're talking about a pressure regulator, they should be hooked up at the other end, where the on/off valve is. Also, you can try a PSI of 50 (but double check your owners manual to see what the recommended PSI is) Also, try the Watts brand.Personally, I wouldn't hook up to a city water without a Pressure Regulator. Too much of a risk otherwise.WoodGlue

I use the reducers, manufacturer says 40psi is max for the pec plumbing. Also, use aftermarket shower head.

If I recall correctly, PEX plumbing is rated for 40-60 PSI, but anyone wanting to use anything over 50 should check their owners manual.WoodGlue

Is this the original shower head that came with the new trailer or one you used as a replacement?You have to abide by the manufacturer's pressure restrictions in the owners manual. Unless there is something in the shower line that's further reducing the pressure I would think the only option is to find a shower head that decreases the volume of water put pushes it out at a higher pressure.

You don't say anything about low pressure elsewhere so the first thing I would do is remove the shower head and make sure there is no debris caught up in the shower head itself. Next I would purchase a Watts 263A pressure regulator with guage from th RV Water filter store. Probably one of the best regulators around as it allows more volume than the cheep regulators.

X2.

It's not the 40lb pressure that's killing the shower it's the volume. Most of the $10 inline only flow about 1-1.5 GPM. The Watts flows over 3 at 50 PSI and is adjustable for pressure. A world of difference. Also get an Oxygenetix shower head, abt $35, another big difference.

X2 to both of the above!

10 feet of elevation change will effect the psi by about 4.

Boozecamp, you sure you don't have a built in regulator? Some of the newer trailers do. Maybe you have 2 hooked up in series?
