You don't want actual 1" hose with threaded ends. Buy a kit sold for
installing sump pumps. It has the 1" hose and the barbed nipples and
hose clamps. This is definately the way to go for any sump pump. I
have three in different areas of my yard and all have this upgrade. On
volume, I used a 1/4 HP sump pump with 30' of 1" hose to empty a 60,000
gallon swimming pool in 12 hours. That's with 18 feet of head (the
pump is 18 feet below the output of the hose)!
