I have a 2 position slide valve on my DE swimming pool filter-how does it work?

Question

It is a Pentair slide valve. There are 4 bolts on it at the top, each look to be locking bolts or something. How do I operate this valve? I don't want to break something by removing something I shouldn't.

What do I do to backwash? Are there any other settings?

Answer 1

make sure pump is off before moving backwash....MOST backwash slide valves go up to backwash,down to filter..run untill water is clear..after backwashing for the third or forth time,you must take filter apart and manually clean it to remove D.E. buildup between grids

Answer 2

it should turn then pull up to backwash dont forget to add the de back in after you backwash
