I am replacing my old Sta-Rite filter, what else besides the quad filter do I need to buy?
 Reply

A  Answered on 4/26/2013 by InyoPools Product Specialist Patrick P.

The only piece of equipment necessary for installation is the purchase of a valve.  The valve options for the Quad D.E. Filter are listed by port size, measure your pipes to determine the best fit for you. 261173 - 1.5" Threaded Multiport Valve 261055 - 2" Threaded Multiport Valve

I want to replace a DE grid filter (has old push-pull valve) with a Pentair Quad 60 DE filter and include a multiport backwash. I am handy (installed a replacement pump before with challenging pvc runs and turns). Assuming the instructions are clear and I have all easy to connect connectors (whisperflo-intelliflo??) is this a DIY project? I live in mountains and installation charges are outrageous due to travel.

Hello Ron - The installation of the filter is not difficult. If you can cut and glue pipe, you can install this filter.

I have a 16x36 pool, It's a NSF 60 now and the upper have is cracked and needs to be either fixed or replace the whole filter. Is that sufficient for my size or should I get a bigger filter?
 Reply

A  Answered on 7/27/2015 by InyoPools Product Specialist Hector F.

Yes, as far as square footage needed for filtration for this size pool, it is plenty. Just be sure that based on the feet of head at your pool and the gallons per minute rating on the pump, that they are compatible with this filter.

I have the Quad/ DE Filter 60. I need to open the drain plug but it doesn't seem to give easily and I don't want to break it. Are there any instructions and cautions I need to know. ie does it open clockwise or CC
 Reply

A  Answered on 3/28/2016 by InyoPools Product Specialist Hector F.

Unfortunately there are no instructions to loosen the drain plug for this filter. The end should be able to use a wrench or ratchet to loosen as well. It is a standard left turn to loosen. If it breaks then it is likely due to the parts being brittle from sun or chemicals.

I have a Starite filter and system around 18 years old. Large black tank with tall narrow filter and one very large filter surrounding the smaller filter. Pressure stick in the middle of both filters. I appears I can just unscrew it and add this Pentair filter to the system. I can send a picture if you like. My question is do I need new valves when I already have them. It appears an easy changeout. 1.5 hp pump. Pool size is 16000 gal. 12 x 15 pool. Thanks James 458-215-9607

Looking to replace my Hayward Pro Grid DE filter with a Pentair cartridge DE filter. Not a big fan of backwash valves and would prefer not to install one if I don't have to. Currently use a Hayward slide valve that requires periodic maintenance to prevent it from leaking. Can I just plumb the filter without a a backwash valve and simply remove the cartridges and clean them individually when they need to be cleaned? Thanks.

A  Answered on 1/9/2017 by InyoPools Product Specialist Adam Y.

Good afternoon Paul, It is possible but getting the D.E out of the tank will be hard. There is a drain plug at the bottom but could be done. It would be like doing an annual breakdown every time you clean your filter.

I have a 36000 gallon pool with a Pentair Intelliflo pump. Is the 80 or 100 sq ft filter the better choice...and why?
 Reply

A  Answered on 3/3/2017 by InyoPools Product Specialist Lennox H.

Hi, The Quad 80 or 100 will be better because it has a higher filtration capacity which will allow you to go longer between filter cleans and lower head pressure maximizing water flow.

I am limited to a 1hp. 1 speed pump withe 1.5" pipe for my in ground pool. Would there be any point in my buying a back flush valve for this filter as my flow rate is way below what they call for?

For this filter to operate properly you would need a backwash valve and for your set up if using the Quad DE Filter we do suggest a backwash valve.

Hi. This filter is for an inground pool and will be sufficient for a 20'x40' pool. You'll have to be sure that your pump flow rate does not exceed 120 GPM.

I recently bought all new filters and they ruptured after two weeks. The starting psi is 10 and rises to 11. I don't understand why the filters would rupture at such a low pressure. My setup is simple. Pump 3/4hp > Pentair 261152 multiport > Quad 60 filter (top inlet) > filtration > Quad 60 filter (bottom outlet) > pool. Do not backwash ever and I added 6lbs of DE when new filters are added.
 Reply

A  Answered on 6/25/2017 by InyoPools Product Specialist Hector F.

There may be a number of reasons that these could have ruptured prematurely. Just as an example, some systems may have pressure fluctuations due to a number of system settings which can cause damage to filters. We recommend getting with the retailer that you purchased them through and run a warranty claim to see if your instance would be covered.

Someone told me that i needed to order a larger filter if I was going with the Pentair Quad. I currently have a 60, so they said I needed an 80 quad. I think my pool is 10,000 gallons. Can I use a 60 ?

Allen, the Pentair Pool Products Pentair Quad Cartridge / DE Filter 60, will be sufficient for your 10,000 gallon pool. You can go with the Pentair Quad Cartridge / DE Filter 80 - 188593, but the 60 is ample. The 80 has a higher filtration capacity which will allow you to go longer between filter cleans and lower head pressure maximizing water flow.
