Yikes 50 feet of elevation!!! That would run into some big bucks for sure.
I have also heard of using the larger pipe to create a greater pressure. When I had once asked a local guy who installs the pump/tank system like I now have about increasing the pressure he said to either use a submersible pump or increase the size of pipe from the tank to the house or both.
We are not very hilly down here but I assume that the elevation of the land would be included in the total elevation above point of use, the house?
Oh and I am used to a lower pressure out in the country than what we have in the city so your 20 foot of elevation and larger pipe may be just the thing ;o)
I would need to figure out the max water used in a normal 5 day period and use a properly sized tank for that need. That and a few $$$$ and I'll be set ;o)HA!!!
THANKS!!!

Wow thats a huge difference even between the 1/2 and 3/4 inch pipe. I had though to go with a 1" or better and adapt near the house but do not see a real need to do so now.
Thanks again Gary.
