Sand Coming Out When Bacwashing
Sand Coming Out When Bacwashing
I was backwashing my filter at the end of the 2007 season and usually run the hose out to the street. When I walked out there to roll the hose back up, I noticed filter sand on the road. What could cause this?
Thanks.......Pete

Backwashing your filter
Sand in the waste water is usually a result of one of the following:
- the pump is too powerful for the filter (or the filter is too small ...)
- the filter was overfilled and the excess sand is coming out
- the sand level is too low and the water flow is easily lifting the reduced sand bed
