Except for the part about checking the filter for leaks and tears, I disagree with the answer directly below. First, it is unlikely that DE expelled into a pool will settle out. It will remain in suspension, especially if people continue to use the pool or if the filter continues to run. At the very least, the pool will be cloudy and uninviting. Second, even if the DE did settle out and people walked on it, it's hard to imagine they would be able to pulverize the microscopic particles any smaller than they already are. Third, even pool-grade DE, which has been heat treated to crystallize the silicon dioxide, is an eye and mucus-membrane irritant. Swimming in a pool contaminated with DE can lead to eye and sinus infections. No, not really, would be the short answer. If people walk on it, it just breaks down into smaller fines. However, the filter needs to be torn apart and checked for leaks.

All wrong above. How gross ! D.E. returning to the pool indicates that you have damaged filter grids. The filter needs to be disassembled and the grids replaced. Damaged grids just return more debris and does not filter out other contaminants. The clean and working filter with the addition of chlorine combine to keep your pool looking like you actually want to get into it. With all that is coming back to the pool added to what you are adding to the pool by using it is a scene for disaster health wise especially if you have a cut or if you are a female.

Face it the pool water is not going to get better and will eventually crash. You are not looking for leaks, you are looking for torn cloth on the filter grids of which there are 8.

I can almost say that your filter has not been broken down for service in 8 to ten years. Your filter and your friends and family will be thankful that you took care of a potentially harmful situation. D. E. will settle out overnight and can be vacuumed up but if the grids are bad that won't work now will it.

The first question to ask is are you getting suction from the pool, When the sand filter is cleaned the pressure goes down. So the only thing you should worry about is. 1 The filter should be set on filter. you should be getting strong suction from the suction side outlet of the pool. and you should make sure you are not sucking air into the skimmer.

Why does my pool filter blow dirt into the pool?

I assume you have a sand filter if so you most likely have broken laterals in your filter. A lateral should allow water through but not sand. if you have a DE filter and you are getting what appears like sand in the pool, you have one or more of the filter grids that have holes and the DE is passing through the filter grids back to the pool.


What is the difference between filter and recirculate on a pool pump?
