Water pressure regulator 2004 Sightseer

My manual says the water pressure regulator should be max 40psi. I am having trouble finding a regulator this low. Any thoughts??

What manual are you referring to. I've not heard of any restrictions that low. Generally these MHs can run 55-65 without issue although most keep it somewhat lower.

Hi and welcome to the forum.

Many of us use a Watts, whole house pressure regulator. They can be adjusted to nearly any PSI limit and cost about $60 at Home Depot, Lowes, etc.

BTW, 40 psi sounds a little conservative to me but it's a good place to start.

40psi is the max the Winnebago Sightseer manual says: "We recommend a regulator that controls water pressure to 40 psi maximum"

My Watts came pre-set at 50psi and I have never adjusted it. Bought it in 2005 and it still works great, and have never had any plumbing problems.

Flow Limiter

The ones that are not adjustible also limit flow a great deal. After many years of suffering with low flow (sounds like a prostate commecial don't it?) I switched over to a Watts. What a difference! I keep it set at 50psi and enjoy showers as good as I can get at home.

At 40PSI the flow is still better than the old regulators with the Watts.

I suggest using a washer with a filter screen on the input side of the regulator.

Perhaps Winnebago specifies 40 psi so you won't buy one of the cheapo 'pressure regulators' that restrict flow more than they regulate. Could be a wise move on their part......Or a vast conspiracy to run Campco and other distributers of the junk regulators out of business. Yea, maybe this was suggested by Watts so they could grab the market!!

My manual doesn't say that and Winnebago told me they test to 80 or 85 psi (I forget which) and they said I coud set my regulator to 65 psi and it wouldn't a problem.

My Watts whole house regulator is set to 65 psi and I have spent entire summers with supply pressures of over 100 psi and the output line pressure of 65 psi caused no problems.

Side note: The supply pressure at our summer home in Palisade CO is 130 psi and there is a Watts regulator on the supply line. It is set at 65 psi also. That is what the town and our plumbing tech recommends.

This is the one I ordered as it is high flow and adjustable.
