Welcome to the irv2.com RVing forums! You'll find lots of knowledge here, perhaps not in the first response, but it's here.
I'm not familar with this brand/model but help is on the way. By any chance does your coach have a water pressure regulator? These have been known to corrode and reduce flow, or stop it completely.

David, not on all brands/models; but, on some the design engineer in all his wisdom called for 1/2" lines into the tank. From the outside all looks ok,i.e. it has a female 3/4" hose fitting; howver, on the rear side of that fitting there is 1/2" PVC. Yes, I know I did not believe it either ubtil I took mine all apart and only then did I find out why the slow fill and/or pressure, Ken, '04 DSDP....

First run tap without hose connected how is pressure. If good next check all filters starting with small washer screen, next house filters, then check for regulator-smaller water line. One of these should end problem.

Hi David,

We moved our pressure regulator so that it sits AFTER the filters to improve the pressure in our coach. Now when flow isn't good AND we know the the pressure at the park is good, we change the filters. Works for us every time.

After an experience I had last June, the first thing I would do is disconnect the hose from the city water imput to the MH and make sure you had good water entering the MH.

We set up at a COE park just East if Ft Myers and had EXTREMELY low pressure inside....every spigot, toilet, etc. (Turned on the water pump and had good pressure from the water tank.( I did the obvious things of removing the outside filter, changing the pressure reducer and even removing the reducer. Nothing helped. I finally had a light go off in my head and checked the basics of seeing if I was getting pressure into the inlet before I started going into the backflow, etc inside of the MH.

Well, there was practically no flow into the MH and upon further checking, I found that a little 6" hose that has a spring around it to allows the hose to make an easy 90 degree bend without crimping had delaminated and collapsed shutting off the flow. I had another one in my box of water/plumbing 'stuff' so I replaced the bad one.....AND, had no further problems on the rest of the 2 week trip.

Good Luck and please let us know what you find. I always like solutions to put into my data bank for that time I have the same problem on the road.

Another "duh" experience I have had when I found I had almost no water flow when on shore water was due to "forgetting" to change the valve from "tank fill" to "city water" after filling the tank. Actually, that happens to me several times a year, and I have finally learned to make that the first thing I check when I find I have very little water pressure when connected to city water.

Purchasing a pressure guage that can be screwed on before your hose or after the hose can answer a lot of questions. I found one at camping world.

First I would like to welcome you to IRV2. I believe you have found the friendliest site on the Internet. As you have already been told we have a gold mine of experience here to help answer your question.

I am going to shortcut your post to the Winnebago Industries Owner's Forum where I believe you will receive additional response. I encourage you to drop in there and ask any additional questions you may have. While there feel free to request some Winnebago Karma.

I had a similar problem while using a small brass pressure regulator at the faucet. I purchased a bigger whole house pressure regulator from Home Depot and that solved my problem. On another occasion I found an obstruction in my check valve which is located behind the hose connection on my panel.

Please post your solution to the problem as we all learn from each other as we solve problems.

Putting the pressure regulator after your filters is not a bad idea. However you should put another one on the campground faucet to protect you hoses and filters from to much shore pressure.

Two years ago we were at a campground. I had hooked the hose to the faucet, then a cheapee in line regulator at the water inlet on the MH.

The campground water pressure burst the hose close to the faucet and the water ran most of the night.

Camping World has two regulators. The standard regulator is set at 45 psi. They have a Hi Flow regulator which is set at 55 to 60 psi. Can the Hi Flow higher pressure regulator be used in today's RVs?

Bill, the best thing to use is a "whole-house" regulator from Home Depot or Lowe's. Most of the folks there have never heard of one, but have them do a search on their computer. You will have to add hose end connections and a pressure gauge. It is adjustable and much LARGER flow orifice than the over-priced junk from Camping World.

The problem is not the pressure setting, but the regulator is just too small (internally).
