Iplay I would love to use 1/2" Pex, but everyone I am talking to says pushing through that small of a pipe causes more load on the pump do to resistance. Have you built one similar before? I have read that some housholds use 350gal a day, but for the two of us I will bet it's under 100gal a day(well.... that's before Lesley starts taking those long soaking baths in her clawfoot tub)
Sorry I haven't made time to check the forum for a few days. The 1/2" pex would put a load on the pump only if you were at higher pressures and higher flows. At <1 gpm and 5 PSI or so, there would be no need to go bigger. The only reason I'd consider bigger would be to leave options open for future expansion. 1/2 inch pipe will handle up to 14 gpm at typical household pressure with minimal flow and pressure drop (See this link... GPM/GPH Flow ). I've never built a system like we're talking, but I think 14 times larger than needed is plenty of reserve capacity for the flow.
Here's another brainstorm... Can you determine where the water in the spring is coming from? Is there a possibility of tapping into the same water supply closer to the house?
