I have a 400 foot deep well, have not yet put in a pump. Water at 300 ft., 6" steel casing. I was planning to use 1" drop pipe for the pump up to the pitless. Recently I found a good deal on 1-1/2" stainless steel schedule 40. Question is- is there any problem with using a larger pipe size like this?
The pitless adapter (already installed) is a 1" stainless steel, the pump will be a Flint and Walling 1hp 7gpm. Total dynamic head, using 1" pipe in the calculations, comes out to about 365 feet, but with 1-1/2" pipe that will come down a bit due to lower resistance. Pipe from well to storage tank is 230' of 1" poly. No pressure tank, just filling storage.
Will 400' of 1-1/2" pipe hang OK on a 1" pitless adapter? I'll need to get reducers, etc., so the 1-1/2" pipe will be hanging on a 1" close nipple at the pitless adapter. I can swap out the adapter if necessary, or maybe get a sch. 80 or 120 close nipple for the hang.
Any other problems? I'm gonna have a pro with a boom truck do the install. I'm not messing with 1000 lbs of pipe.
