After spending a restless night (did I mention that we are planning to leave on a month long trip next Monday, the 7th of July) trying to figure out how to locate where any cracked pipes ARE and how to get to them and how to repair it or them.
The duct work, electrical wiring (both 12V & 120V) and hot & cold water lines are run under the floor with cable ties securing them to the steel frame, wedged between the gray & black water tanks and the floor.
I couldn't think af ANY way to get to any part of the water lines.
So I gave up.
Our home has a water manifold with individual water lines running from a valve at the manifold to each specific faucet.
I decided to replicate this idea.
I found various plumbing diagrams for the 04, 05 & 06 Dolphin (thanks be to you wonderful folks who captured and posted these diagrams
) and decided to by-pass the works and re-pipe the whole system (hot & cold) if necessary. Then I discovered PEX and Sharkbite products
. I made a spread sheet based on what the local big orange box store had on hand and headed out to spend money.
Before I did anything, I had to know if there were any cracks in the hot water lines. I had already extracted the manifold panel so I took the time to label each line (hose as found behind your washing machine) with a black sharpie with arrows showing water flow direction. I disconnected the cold water supply from the small pex(?) water distribution line and put a plug on it (the water hose attached to the manifold). I then set the valve to fill the hot water tank from city water and went into the MH and opened the hot water at the sink, lavatory & shower. When the air was forced from lines, shut them and waited for any leaks to show up.
WOO WOO - NO LEAKS IN THE HOT WATER SIDE
I then spent the rest of the day figuring how to run the cold water line to the kitchen for the sink (sink & spray wand & filtered water tap). If the cook doesn't have water at the sink - nobody will be happy!
I ended up putting piece of 3/4 CPVC as close to the underside of the floor as I could and against the outside wall of the wheel well for the duallys and ran the PEX water line inside it so that it will have some protection from road stuff), then snaked the line across the "basement" near the underside of the floor.
Tomorrow I plan to bring that line up through the floor near where the gray/waste water pipe leaves the cabinet.
Next will be the lavatory and spray wand for the commode, then the shower.
More to come.
