Best plumbing materials for a leaky 2012 bighorn

It's used on full hook up sites. I've used a regulator. The first was on the hot water tank under the kitchen counter. A plastic compression type fitting came loose and flooded the lower portion of the camper. Lucky I was leaned a little and most water ran out under the living room slide. It's just depressing to pay for a mercades and get yugo quality and craftsmanship. I'm sure heartland at most would say bring it to the factory hundreds of miles away for who knows how long and still not stand behind it. The water lines and care of construction will the the first things I look for when I buy another. If they sold for $15,000 I'd understand cutting corners, but the sell for $55 and up! The cost of luxury cars! This is also the second power converter that has been taken out by the water leaks, I guess someone at the factory thought in the center of the water lines was the best place to install the power converter so it gets drowned with every leak.

I've come to the conclusion this am that my 2012 heartland bighorn needs compleatly re plumbed. I woke up to my 4th bad leak, fittings are comeing apart at random, plus the lines look like they were installed by a child at the factory. Everything is intangeled looks like an absolute mess. Then add wiring and duct work all twisted together and it's a mess. My RV is getting ruined little be little. There has to be better plumbing materials vs the cheap, no craftsmanship way this thing was slopped together. Some lines need shortened and better clamps need to replace the crimp on style. Any suggestions for better materials? I'm at a loss, less than 4 years old and rotting away.

It might be worth a call to Heartland customer service. If you get lucky, some of the problems might be reparied by Heartland via warranty or in the interest of Customer relations.

A properly installed PEX fitting will not leak. Emphasis on PROPERLY.

But it's a good idea to use a pressure regulator when water pressure is an unknown.

X2 on the PEX. There are a different methods to attach the fittings.
Do a little research and decide which is best for you.

Sharkbite fittings are probably the easiest but, they are somewhat expensive. It depends on how many connections/fittings you will need.

I feel your pain on watching something new keep having problems.... My new Cardinal looks like a mess behind the bulkhead wall too in the basement. I had to get in there and tighten all of the water connections, as I had leaks in my brand new unit. Everything is a mess down there. So a couple questions... I've owned 3 trailers now with PEX lines, and crimped connections and never had a problem. so, I'm not sure the materials are the issue in my mind. Maybe craftsmanship, or something else. Just out of curiosity, where do you use your Bighorn the most? Full hookup sites? If so, do you use a water pressure regulator? Maybe you have been overpressurizing your system unknowingly? Are all the failures at fitting connections? Or any mid-line failures? What kind of winterizing process do you use?

Not implying you are doing anything wrong, just asking a lot of questions to get you to think about other ways this could be occurring.
