How do I backwash my Hayward Vertical Grid DE filter?
 Reply

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

When the filter pressure rises 8-10 PSI over the clean starting pressure, the filter must be backwashed. Turn off the pool pump. Rotate the multiport valve to backwash position or slide the slide valve up. When the pump is turned on, the dirty DE and water will flow out to waste. Once the water runs clear, turn off the pump. With a slide valve, push the handle down and start the pump. Once the pump is primed, add the required DE. If using a multiport valve, rotate the handle to rinse. Turn on the pump and let water flow for 20-30 seconds, cleaning out the plumbing lines. Turn off the pump and rotate the valve back to filter. Turn on the pump and once primed add required DE.

This filter model uses approximately 8 lbs. of D.E. powder when completely empty and approximately 4 lbs. of D.E. after backwashing.

I am getting DE back into my pool after I backwash, do you know why?
 Reply

A  Answered on 9/16/2014 by InyoPools Product Specialist Patrick P.

The main reason is that one or more of your grids are torn and DE is passing through. Please remove all the grids and thoroughly inspect each for rips or cracks in the plastic structure. Also check the manifold ( the piece the grids fit into ) for cracks in the plastic. If there is nothing wrong with either of those, one other possibility is that the spider gasket in the multi-port valve may be torn and not sealing correctly.

My old filter pretty much the same a Hayward, around 15 to 18 years old cracked on the top.

1. First I measured the connections up and the old filter and the new filter were pretty much the same.
2. Removed the old Filter.
3. The new filter stood a little lower so I just added about 1/4" of hardiboard on the bottom.
4. The filter screwed into my existing connections perfectly, no PVC work was required.
5. Followed the instructions and added DE earth.

Were these instructions helpful?
