I am getting ready to replace my older FNS Plus 36 which has served me well. I am having an occasional low flow problem with my new HP 140K BTU heat pump showing a "HP" error message which indicates not enough flow for the HP compressor to come on. My question is if I replace my existing FNS 36 with a FNS 48 which shows a higher flow rating, will I get a higher flow rate through my system piping and heat pump without upgrading my existing pump/motor?
Hi, Richard. You will not get a higher flow rate through your system, you will get a longer run time before having to clean or backwash your filter.
I assume I would need a new multiport valve, also filter is about 6 ft. above pool level' Does the filter have backwash capability ?
Hi, Joe. You will need a valve to operate this filter. With the correct valve, you will be able to backwash the filter.
If I purchase this filter, does it come with a set of grids, or do I need to purchase the grids as well?
Yes, this filter comes with all of the grids.
Can the process of installing the new filter can be be a DIY project?
Hello, Here is a great DIY article on how to install a DE filter. http://www.inyopools.com/Blog/poolside-repair-install-d-e-filter/
what multiport valve will go with de backwash filter 180008 FNSP48
Hi, MJ. A list of compatible MPV are available on the Pentair FNS Plus D.E. Filter parts page.
What is the grid size I need for this filter? Item number? I believe I need 7 full and a 1/2 one for a total of eight.
For the FNS Plus 48 you will require this FNS Plus 48 DE Grid Pack the pack includes the 7 full grids and the 1 smaller partial grid.
I just need the band to go around this. and a new pressure gage. what are the parts numbers and how do I get these items?
Do you offer this with filter in 1-1/2" plumbing? Id rather not have to use a reducer if its 2"
Hello- This filter would require a multiport valve to be installed with it. You can use the 1.5" Threaded Multiport Valve for D.E Filters - 261177 instead of using the 2" valve.
Should I use a 36 Square ft triton FNS or a 48 square ft pool is approx. 200000 gallon with one HP Pump
Good morning Tom, I would go with the FNS Plus 48 Sq Ft Filter w/o Valve - 180008
I have a Pentair Filter Part # 180008 on the bottom of the tank is a plug that started to leak water i went to check it and it fell off what can I doe to fix this
PG - I think you are referring to the drain plug at the botton of the tank. This plug should screw back in. If the plug's threads are stripped, here is a link the filter's parts list :Drain Plug (#24) and associated O-ring (#23). If the threads in the tank are stripped, you will have to buy a new tank bottom (#25) or a new filter.
I have a 30 year old sylvan pool with 48 KDI de stainless filter and 6 way multiport americana valve. Please advise on filter and valve selection.
I have a 27 year old 20x40x4 pool with a 1.5 hp Hayward Super Pump and an Lomart DE Filter that developed a slow leak I can't stop. Replacement parts no longer available. There are 30 ft of 1.5 inch tubing from the skimmer to the pump and 20 ft of 1.5 in return line. Pump is at pool water level. The old Lomart has 9 D.E. disk filters with a total surface area of 25 Sq. Ft. I am looking for an over sized D.E. filter replacement. Is the Pentair 180008 one of the better replacements? Can you sugge
Yes this Pentair filter would be a great replacement and considerable upgrade from you Lomart filter. If you go with this Pentair filter then you would also need to purchase the Pentair 1.5" mulitport valve. Thanks for the great question.

Pros: it works MUCH better than my sand filter did!
Filter instructions were vague on the startup proceedure I thought. Nowhere in them did it say that every time the pool is backwashed more DE must be installed. I didn't wnow and asked a friend whythe backwash water was white.
(5 out of 5 stars) great flow rate
Reviewed By: pony from chardon, ohio ()
the item arrived in a very timely manner. the flow rate was much faster than my sand filter. the product was easy to install. one problem was the gauge on top came cracked although it was still usable. i believe the system crushed it in the box.
