Hi, I have a Jandy DEV48 that I bought 2 summers ago. I am having trouble with the filter expelling the DE powder back into the pool. It is obviously the filter is not allowing the powder to adhere to the filter. What do I need to replace or do?

A  Answered on 6/10/2016 by InyoPools Product Specialist Alan M.

Hello Martha, You will need to open your filter and inspect each individual grid and the manifold for any . There is the Jandy DEV Series DE Parts diagram if you need it for reference. The DE powder will flow back into the pool when there is a rip, tear, or crack in one of these parts. If you are unable to locate the broken part, I would recommend you contact a service technician to assist you.

why no pressure

A  Answered on 6/23/2016 by InyoPools Product Specialist Alan M.

The most common reasons you have on pressure are the pump has failed or the pressure gauge is broken.

what does the unit come with and what other items do i need to purchase Martin

A  Answered on 8/28/2016 by InyoPools Product Specialist Alex V.

Martin, The DEV48 is for the filter tank and the "guts" of the filter. Aside from this, you will need to purchase the multiport valve.

I have a jandy 48 sq ft DE filter that was installed with my pool in 2005. the top is faded and blue in color and I can't make out the model number, but the serial number is 2931434, the model looks like maybe SL22JC. It appears to be leaking water when pump is on,(not backwashing). A small amount water is coming out of the backwash tube. It may be a gasket to repair? I don't know what part to order to fix it.

Unfortunately, I do not recognize your model#. It sounds like you have a bad spider gasket in your multiport valve. If you can attach a picture of the filter and valve I should be able to identify your filter and find the correct spider gasket for you.
