Water pump goes inside for us ALWAYS. But we fulltime and end up in freezing weather. Even an overnight freeze is not healthy for a pump. Don't forget to add in a sediment filter to keep your pump safe.

Most mfg's say "for use over 40 degrees--therefore inside. If you want truly quiet operation, spring mount your pump so it does not touch anything else. The springs absorb all the pump vibration that we usually hear.

bring your water line in somewhere that it can be kept warm and keep your lines and pump away from the outside walls to avoid freezing.

you can also use waterbed heaters to keep the holding tanks warmer than freezing...

Re: Plumbing... on the way~! How hard was it to do???

I put all plumbing inside except for the greywater tank. All pipe is 1/2" PEX tubing, for both hot & cold water, with "Flair-It" fittings, Ts, elbows, etc. The water heater is right under the kitchen sink, and only a few feet from the shower fixtures. This minimizes the cold water "slug" that is in the hot water pipes between the heater and the faucet. About 4 cups of cold water comes out of the tap before the hot water gets there. And I capture the slug of cold water and pour it into a water filter that is next to the sink. Anal? Sure, maybe.

Something that may be obvious to everyone else, but I only thought about after the fact, was how I plumbed the outgoing water line in the fresh water tank. The way I did it was to have it stub in from the bottom of the tank, with the end of the pipe protruding into the tank about 2 inches. What I should have done is have it go in from the top and protrude down into the tank, with 2 inches of clearance from the bottom, so it sucks water out like a soda straw. I think the two inches of clearance is important so any sediment can settle in the bottom of the tank and not get drawn into the pipe. But if your pump can handle it, having the pipe go in from the top eliminates having a penetration on the bottom of the tank. One less thing to worry about.

I live in Houston, TX... freezing isn't a big concern but the Pump is going inside regardless. Thanks for the tips!

Re: Plumbing... on the way~! How hard was it to do???

its is also a good idea to have a removeable screen at the outlet of the fresh water tank..
