I am in a design phase for a a rec property down on the lower Kenai Penninsula. Property already has a drilled and cased well (but no supply line installed). Electricity is close by.
I am looking for information on designing a plumbing system that I can shut down between uses without fear of freezing damage. I will probably have a skirted, insulated crawlspace through which supply and drain pipes run. I have done some internet research and see a lot of good products for insulating and heat taping pipes. Good ideas. I understand also that it is common practice to evacuate supply lines and put non-toxic RV antifreeze in P traps to prevent damage to the toilet and shower. I do hope to use the system intermittently in winter but wont be keeping the structure heated (wood stove). What I am trying to figure out is some design ideas that will help me quiclky and easily drain the system back below the frost line, and bring the system back on line again when needed. We are looking at pretty rudimentary plumbing needs: a kitchen sink, a toilet, a shower and bathroom sink. Hopefully all in a single wet wall, but might have to do two walls.
If any of you cabin owners or DIY plummers have advice on dos and donts I would be greatful.
