Will this fit my Titan DE filter?


A  Answered on 5/18/2020 by InyoPools Product Specialist Patrick P.

No this is not the correct valve. You will need either this 1.5" Titan Filter Valve or this 2" Titan Filter Valve. 1.5" or 2" refers to the size plumbing that is going into the valve.

I am looking for the top part of a valve. It is the part that has the different options on it like backwash and rinse. It is for a Pentair 8 position multi-port valve and has a label # 96734200.

A  Answered on 6/19/2015 by InyoPools Product Specialist Hector F.

The top lid part number for your valve is part number 4659-25d and the handle is 4659-21c. These do not come together pre assembled unfortunately.

Hi Ramon, yes we do carry the Top Half of the 261177 Valve if you go this route you will also need the 261177 Spider Gasket.

I need parts for my filter valve. When I look at the filter parts breakdown, it gives me different choices. How do I know which one is the one I need?

A  Answered on 1/31/2012 by InyoPools Product Specialist Patrick P.

In order to locate the correct parts we will need to know the model number of the filter valve. Two identical filters can have two different valves. Typically the valve model will be located on the label of the valve. If there is no model number on the valve, you can try to see if there are any part numbers on the valve itself. Once you've located you valve model you can check out our >Filter Valve Parts.
