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.

We were at Fishing Bridge RV campground in Yellowstone a couple of weeks back. The pressure would exceed 100 psi at times. Glad I had a water pressure regulator.

I have stayed at many parks with pressure greater than 75 psi. I have a gauge installed on the incoming line of my regulator.

yep, fishing bridge had some of the best showers I have ever seen. sort of like a fire hose coming out.

Our shower head had this plastic disk washer looking thing with a little hole in it.

I removed this little plastic disc between the shower head and hose. This made a world of difference.
Also, you can't beat an Oxegenic shower head and a Watts water regulator.

Hi,

Having had to replace a hose I now connect at the bib.

While I understand connecting it at the source would also protect the hose, it would appear to me the trailer would see no difference. Is there a reason I'm not seeing why it "should" be connected there?

Thanks,

I'm just thinking of wear and tear of the water inlet screw on the RV. Probably not a huge issue.

About those Watts regulators,they are great and well worth the price...but....Don't leave it behind when you move. (No need for me to admit to anything here.)If you need to buy a second one,it makes the total cost really high. 'Nuff said?

That's why I connect the regulator directly to the water inlet on my fiver. It stays connected there all the time. I have heard that I will blow out my hose by doing this but I can tell you that in all the years I've been doing this it has NEVER happened.

I'd like to see where you get that.

What I meant to say was PEX is rated for between 40-60 PSI in TRAILERS. I know it's rated much higher for other applications. I just didn't want a newbie to get any wild ideas and crank it up to 80 PSI or whatever.
