Subject to this storm passing sometime today I am in the process of opening up the cabinets and cubbyholes and reworking the storage space. I should say I spent many years doing cabinet installations and finish carpentry, planned rework is no problem. Golly, there are a lot of little passages for the critters, more on that later....
My concern right now is the plumbing....
This thing is loaded with water traps in the fresh water lines so I am thinking about reworking some lines to allow better self drainage and to pick up new storage spaces under the sinks.
Question one, are the pex fittings and tubing something that is readily available at RV dealership and/or at the big box home stores?
Question two, can the same tubing be used for both hot and cold?
Question three, is there a reason why the hot water tank is still working with the propane off and the switch shut off at the convenience center? Is there a electrical element that warms the tank as long as water is in the tank? Fresh water system is still operational, shore line is hooked up and fresh water tank is half full. The water tank's hot water outlet is very warm to the touch.
And the last Question, should there be a valve on the inlet AND the outlet on the water heater bypass? there is a bypass on the hot water tank but there is only one valve on the bypass on the inlet side. Wouldn't that defeat the purpose of the bypass and allow water to back feed the tank thru the outlet? Maybe there is a check valve inside the tank???
