Plumbing Issues

[azpopup17]

I have owned my Mesa for about 8mos now and have gotten some good use out of it.  My biggest complaint has been with water leaks in the plumbing.  My latest was last week when I was pressure testing my plumbing before taking it on a camping trip last weekend.  As soon as I turned on the water, one of the pvc fittings burst to the cold wafer faucet line.  The worthless Fleetwood dealer had no parts or advice for replacing the fitting.  I ended up replacing the entire faucet manifold assembly with one with a brass manifold from Camping World (I replaced the shower one right after I bought with a brass one).  Since these are 1/2 in lines I went to Home Depot and made a 1/2 in to 3/8 adaptor for the pvc for about $6 each.  

If you have a PU that uses the 3/8 pvc lines for the internal plumbing, I recommend replacing the plastic manifolds and fittings before you get a surprise on a camping trip.

I have owned my Mesa for about 8mos now and have gotten some good use out of it.  My biggest complaint has been with water leaks in the plumbing.  My latest was last week when I was pressure testing my plumbing before taking it on a camping trip last weekend.

At what pressure?  The spec is for 40 PSI max.  I always use a pressure reducer, although it is probably not needed in most campgrounds.  One we visited, though, had signs up that stated their water pressure was 90 PSI and that you had to use a pressure reducer.

Every leak we have had (3-4 in 6 years) has been a loose hose clamp.  I think someone at the Fleetwood factory needs a calibrated torque screwdriver to make sure they tighten the hose clamps adequately.

I use a pressure regulator to protect my water lines.  I also use a filter.  

Road vibration has caused some of my fittings to leak, but I've caught the leaks and tightened the clamps.  I am having an issue at present with my freshwater to toilet line as it is leaking - problem being no space in which to work.  And, I am currently physically unable to get into a position (broken leg/surgery at knee) to work on it.  But it's only a little drip!

My Owners Manual specifically stastes that it is important to use an in-line water pressure regulator at the water supply outlet to protect the trailer water system and supply hose from excessively high water pressure.

I had  problems with the plastic galley sink faucet on our 01 Niagara. It would not shut off completely on the hot water side so I replaced it with a brass body faucet. While on a long trip, the shower faucet cracked for no reason and started leaking so I  disconnected it as we did not use it.

Also, the water lines for the outside shower, which were located under the floor in the dinette slideout, had to be replaced twice because the movement of the slideout in and out caused them to leak or break. I disconnected them after the second set leaked and capped off the water to them....Never had any more problems.. Never had any problems with the PEX tubing or it's connections leaking.

I guess I should have mentioned I always use a regulator rated at 45psi when connecting to city water.  The fitting broke where the hose clamp was crimping the pvc line to the connector.  It was nothing to do with the water pressure.  I am guessing it was already broken when I turned on the water.  Luckily I caught it before it made a real mess.  

Rule of thumb.  Always do a pre test before taking the PU out on the road.  Regardless of how old it is.
