    Sundance 310QB water pressure

    Does anyone have any suggestions on how to increase my water pressure in my Sundance 310QB TT? Its pretty low, and its at every faucet, the shower, and even outside shower so I know I don't have a leak or anything. I would try it without the pressure regulator on the hydrant at the campground, but I'm afraid if the pressure fluctuates it might bust a line. Has anyone else with travel trailers experienced low pressure? My old TT was about twice the pressure as my Heartland. It's not so low that it causes problems, but if I could up it some it would be great especially when it comes to the shower. Its the same at every campground we've used so far so I know its not the campground supply. Thanks ahead for the input.

    Sounds like a presure regulator problem to me. Thats the only constant in the setup. Jon

    I replaced the cheapie regulator with a residential regulator. Purchased it from Lowes for about $45. I now have good flow and adjustable pressure setting with built-in guage....works AAA++ set at 45 psi.

    Look behind the docking port====see if there is a regulator in the line. Take it out and use a residential regulator.

    I removed the panel and found just piping. The pipe size looks to be 1/2" OD, thats tell me its only about 5/16" on the inside which will never flow well. There's also soild 90 deg. elbows used too so the inside diameter of that fitting is smaller yet.

    I'm pretty sure all the plumbing in all of our rigs is 1/2" ID. You might have a restriction at the city water connection in the UDC. OR the little screen may have some debris causing low flow. Just my thought.

    Ray.... I'll go try to take a photo of the piping and fittings (tee's, elbows) next to a tape measure. The outside diameter of the pipe is 5/8". The tee's and elbows OD is 1/2" these are inserted inside the plastic pipe and clamped, that means the ID inside diameter at the clamped joints is around 3/8". That has to cut back on flow?

    regulator

    I have a 31QBS and my water pressure is low as well. I looked at my regulator and found it is only a 2-2.5 gpm I just ordered a new Watts Brass Model N55B Adjustable Regulator, 25-65 range, 6-9 gpm from the Water filter Store. Here is the link It is not cheep but I like pressure to take showers . I already changed out my shower head to one of the Oxygenics heads. It helped but not much. I'll let you know if the new regulator helps.
