Instead of switching out valves, would it be acceptable to put a plastic or concrete slab underneath this filter to make up a 1-inch difference?

A  Answered on 10/10/2018 by InyoPools Product Specialist Hector F.

If you current multiport valve matches the portholes on the filter then it may be compatible. You can always provide us with the model valve that you currently have so we can confirm compatibility. If you do not have that information then you can email us images to upload@inyopools.com so we can confirm for you.

I have an older PacFab 60 DE filter. I was looking to replace it with this one. It looks like the outlets are about an inch lower than on the PacFab. Are there any trade secrets to bridge that 1 inch gap or will I need to buy a new valve as well? Don't have a lot of PVC to work with on the top outlet.

A  Answered on 10/10/2018 by InyoPools Product Specialist Hector F.

So when the port arrangements are different you, unfortunately, would have to change the complete multiport valve.

I have an older Pentair Nautilus FNS 60 with a drain plug in the rear of the lower section. The unit is starting to leak and I want to replace it with a new FNS PLUS 60 unit. Will the plumbing on the FNS PLUS 60 line up with the plumbing of the older FNS 60? The lower opening connection is 9 inches above the ground and the top opening connection is 71/2 inches above the lower opening connection.

A  Answered on 7/10/2018 by InyoPools Product Specialist Lennox H.

Hi, George. The FNS Filter plumbing/valve connections are 1" high than this FNS Plus filter. So the plumbing will have to be slightly adjusted or the filter will have to be raised by 1 inch.

I have a 30,000-gallon pool. A pool service company replaced the Hayward 1.0HP pump with a Jandy Pro Series Plus HP 1.5 HP pump. It would appear that my Pentair FNS plus 48 cannot handle the pressure. The starting pressure is 20 PSI; before the starting pressure was 10 PSI. It quickly goes to 30 PSI. My question is would getting a new larger filter unit like the Pentair FNS plus 60 reduce the pressure since my current filter is 12 years old or should I replace the pump?

A  Answered on 6/28/2018 by InyoPools Product Specialist Lennox H.

Hi, Paul T. Yes, a larger filter will allow your system to operate using a much lower system pressure.

?     Asked on 6/27/2018 by Paul T.

Last year my pool service company replace my Hayward 1.0HP with a Jandy Pro Series Plus HP - PHPM 1.5. I have been having problems with my Pentair FNS Plus 48 Sq Ft DE Filter. Before the pump was replaced the starting pressure was 10 PSI. Now with the Jandy Pro Series Plus HP - PHPM 1.5 the starting pressure is 20 PSI. Instead of replacing the pump again, I was thinking of replacing the Filter to Pentair FNS Plus 60 Sq Ft Filter. Would this lower the PSI?

A  Answered on 7/3/2018 by InyoPools Product Specialist Lennox H.

Hi, Paul T. Yes, increasing the filter size will reduce the filter's operating pressure.

i have a pac fab 48 de filter can i hook up 180009 fliter would it help keep it cleaaner 0r should i go with a 180008

A  Answered on 6/2/2018 by InyoPools Product Specialist Lennox H.

Hi. You can replace your existing filter with the FNS Plus 48 - 180008 which will give you the same filtration. Going with FNS Plus 60 - 180009 will allow you to backwash less and a better flow rate.

?     Asked on 6/22/2017 by cindy

how do you backwash and when do I backwash?

A  Answered on 6/23/2017 by InyoPools Product Specialist Lennox H.

Hi, Cindy. This filter requires a valve that you allow you to backwash the filter. You would backwash the filter when the current filter pressure exceeds 8-10 psi above the starting pressure.

I cleaned my de 60 sq ft filter grids and see no holes in the screens. Three grids have a few broken internal fingers on the bottom sections inside the cloth screen with no cuts tears or holes. I am getting DE powder into pool. What is wrong? Any suggestions how DE is getting through the screens and into my pool?

A  Answered on 1/11/2017 by InyoPools Product Specialist Hector F.

There could be a number of parts that may have gotten damaged which can cause this issue. The grids, standpipe, standpipe o ring, manifold, or even the spider gasket or seals in the control valve attached to the filter. Just have to inspect them all for damage or wear.

Hello. I currently have an old Nautilus FNS 60 D.E. fiberglass filter installed. I also have the multi-port valve. Will a new FNS Plus 60 Sq Ft Filter directly replace the old unit without requiring plumbing changes (basically, will the two bulkhead connections out of the multi-port valve line up)?

A  Answered on 7/22/2016 by InyoPools Product Specialist Lennox H.

Hi RDW, The FNS Plus 60 will be a direct replacement to the Nautilus FNS 60. The valve height might be 1" lower on the FNS Plus versus the Nautilus FNS.

I have a DE filter with a home I just purchased. I replaced the motor with the V-Green I purchased from inyo last month. The cartridge seems to leak from where the valve attaches to the tank. can this leak be stopped if in the seam? Thank you in advance for your help with this issue.

A  Answered on 6/9/2016 by InyoPools Product Specialist Lennox H.

Hi Gino, If the tank is leaking beacuse of a crack in the unit then you will have to replace the Bottom Tank Assy-170018 or the Bulkhead O-ring which can be found via the Pentair FNS Plus D.E. Filter Parts page.

I need to replace my DE pool filter, which is a Nautilus NS 60 Pac Fab, stainless steel. Is your Pentair FNS Plus 60 sq ft and a 2" backwash valve compatible?

A  Answered on 8/11/2012 by InyoPools Product Specialist Patrick P.

Yes we would definitely suggest the FNS Plus 60 as a perfect replacement DE Filter for your Nautilus NS 60 Pac Fab, stainless steel filter. The plumbing ports will not be in the exact location as your old filter, so there will be some minor re-plumbing required. The 2" backwash valve is purchased separately, thanks for the question.
