Couple of Pump Questions
I am about to install a sprinkler system that will be fed by a 1 hp? pump. I had toro design my system for me. I have a couple of questions though:
1) I am having PVC come off the pump to the control valve and is there a certain length that this should go before it turns if at all.
2) Do I need a back flow device for the pump or anything between the pumps and the valves?
Thanks for your help
1. short answer no but why do you ask/why are you concerned?
2.are you pumping out of a lake/river?
Thanks for the quick reply.
1) I thought I read somewhere that it was not good to have a 90 turn close to the beginning of the pump line and that's how the system was designed.
2) I am pumping out of a canal sort of like a lake/river.
Thank you
Dont worry about a 90 being close to the pump.
I cant think of any reasons why you would need a backflow devise for doing what you are doing (pumping out of a canal). But make suer the water is getting filteredso debris is nt plugging up your heads.
