Why is my pool filter blowing out sand after backwash?
Sand coming from the pool filter is the sign of a broken component in the filter. If you see it blowing out into the pool, something is broken. The most common problem is a cracked lateral, which is one of the perforated pipes at the bottom of the filter that catches water that has circulated through the sand.
Why is my sand filter leaking sand into the pool?
If your sand filter is leaking sand, into the pool, constantly (not just after backwashing), this is usually a broken lateral. Laterals are plastic parts at the bottom of the sand filter, with slits so small that it keeps out sand grains, until it cracks that is.
Why is my pool filter blowing out dirty water?
It could be a clogged pump basket, clogged impeller, clogged pipe or clogged skimmer. It could also be a closed or broken valve before the pump. Or, the pump may have an air leak, and is drawing in more air than water, which will also reduce the filter pressure (and filtration).
What happens when you backwash the sand filter in a pool?
When you backwash a pool, or more correctly, backwash a pool’s sand filter, you are reversing the flow of water through the filter. The water passes through the filter from the bottom, rather than from the top, and dislodges all the dirt particles lodged in the sand.
What does it mean to backwash a pool?
Backwashing a pool is a simple, straightforward process that involves switching the multiport valve setting of the pool sand filter to “Backwash” then running the pump for a few minutes. This reverses the flow of water in the filter which flushes the dirt out of the sand.
How often should you backwash a sand filter?
If we have young family staying and it gets used all day every day then I may need to clean and backwash every few days. It depends too whether you have a sand filter or a DE ( diatomaceous earth) filter. DE filters should be backwashed less often than sand filters, perhaps as little as every 4-5 weeks.
Where can I get a sand filter for my Pool?
Basically, the nearest pool store is 300 miles away in Tucson. I am thinking that I should add the chlorox directly into the skimmer with only the skimmer valve open and give the sand filter a good sanitation this way. The chlorox obviously would then go directly into the pool and kill the algae.
How do you backwash a Pentair Superflo pool?
It’s a 2hp Pentair superflo. Normally, I very quickly go from filter, then pump off, then valve to backwash, then pump on, and I get backwash flow within seconds. However, when I went to backwash it, it took a very long time to prime to backwash (I have a Pentair Sand Dollar filter).
Why does my Pentair sand dollar filter not backwash?
However, when I went to backwash it, it took a very long time to prime to backwash (I have a Pentair Sand Dollar filter). And then after the backwash, I waited for 10 minutes to rinse but it never flowed to rinsed. The pump was running but there was nothing but churning water in the pump bowl.
