I'm at 1700' elevation and drawing 12' vertical using a 1/2 hp pump , 1 1/4" pipe, and a well point. This services a camp with low water demand. I'd like to replace the old galvanized with pex or black poly and move the pump as well. I can't locate anything other than 3/4" pex, but can get larger diameter black poly. If I move the pump it'll be 30' horizontal from the well. I believe 3/4 may be too small a diameter, but if it's not is the friction loss too great to use it? And if I go with 1 1/4 is the 30' horizontal a problem? Thanks
