2. Shore water off and pressure bled out when departing for more than a day. The reason is that the pressure regulators are poor quality products and I have replaced 3X. Also guest shower once dropped for days and could have overflowed the shower
pan (that pump is apaniah pump not auto like the master sump).
3. Always shut down HWHs when gone for more than one day.
4. Always shut Vaccuflush pumps when away for more than one day.
5. Always shut down fresh water pressure pump.


Just a FYI. This will not guard against water pressure even if you close it 99.9% of the way. You will only reduce the volume of water that can flow through the valve which has no bearing on pressure.


+1 on the comment about pressure and volume

I turn everything off, every time. No sense in tempting the fates, poltergeists, karma, etc.... If it can go wrong, it will go wrong....

Only because I'm "that guy". . .I'd like to point out that they are just "water heaters" as hot water doesn't need to be heated :whistle:

Anyways, I leave my water heater off until I need the hot water. 6 gallons doesn't take long to warm up and I have only used it once so far to wash some dishes. The boat is new to me still, and I'm sure I'll probably get to a point of just leaving it on as the convenience of "hot water on demand" sinks in. On my sailboat, I had to boil water on the stove and then mix it into a garden sprayer to do dishes :pinch:

Water system I tend to leave on.

I live on my boat though. If I were to go away for a couple days, I shut everything down and let the marina know to keep an eye on my boat.
