The original main line wasn't thought out too well, it is a 2 inch irrigation poly line that is rated for 100 psi and I have pressures that are right there all the time. The current line handles 30 gpm but I would like to add another pump and boost the gpm to 60 and that is more than the current line could handle and would push me past or right to 5 fps. I am also planning for the future in that I may someday install a third pump so that is whay I want to use 4 inch just in case I ever want to go to 90 gpm.
Are schedule 40 gasketed pvc fittings super expensive? I would think that they would be and that may prevent me from going that route and force me to solvent weld. Thanks for the suggestions
