My system 3 ( s7m120) is 17 years young. I just spring cleaned my cartridges (annually) and when putting the top on and using the 6=7 knuckle fasteners, the unit is leaking at some of the knuckle connectors. can you buy the knuckle connectors if they are not providing a tight grip? It wasn't leaking before I started to take it apart to clean the cartridges... HELP
After reviewing the parts diagram for your filter, there is no part referred to as "knuckle connectors" but if you click here you will be directed to the parts diagram for your filter and can see the various fittings and seals that may resolve your leak.

Hi, Tom. The correct cartridges were ordered for the S7M120 model.
I would like to know if there are any dealers in Pasadena, Maryland that can show me how to hook up the filter for me? I just moved into this house and don't know anything about the filter.
We do not have any dealers but we do have a DIY Resource tab on our website that has many videos on working on pool filters.

Good evening Rudy, If you are refering to jandy valves than no
We installed a S7M120 Sta-Rite Filter---3 Years Ago--- We Now Have installed A Heater-- This year--- Its odd that Every time the GaGe on the Filter ----once it reaches----the No 40----My Heater tells me NO--FLOW--IT STOPS WRKNG-- I CLEAN THE CARTRIDGES----& IT WORKS (HEATER IS A JANDY PRO SERIES JXI) SOMETHING IS WRONG HERE OR AM I DOING SOMETHING WRONG
Hi Louis, As the filter get dirty the water flow through the filter decreases providing inadequate water flow to activate the heater water pressure switch. If you're having to clean out the filter more often then it sounds like the filter module has reached the end of it;s life and will need to be replaced.
Hello, our pool is 9 years old and we are replacing the cartridges in our filter. Does this filter require any sand at the bottom or is it only the cartridges that do the cleaning? Thanks!
Hello Juley, This cartridge filter cleaning system does not require any sand to aid in the effectiveness of the filtration. The cartridges will be sufficient enough to filter the pool water on their own. Thanks for the question!!
can I replace the lower filter body? Mine has a crack. The filters are fairly new.
The S7M120 lower filter body replacement is part number: 24850-0102S

This is a complete filtration unit.
My pool surface area will be 380 sq ft. Do I need the 400 or is the 300 the pool company wants to install sufficient?
Hi, This unit can filter up to 48,000 gallon in an 8 hour time frame and can handle a flow rate of up to 80 gpm. Which is sufficient for you pool, if you want to can go with the S7M400.
Do you provide names of local installers that we could call. We live in zip code 02152
We are simply a on-line retailer in Orlando, Florida and don't have contact with outside installers. It is possible if you were to call Pentair ( who own Sta-Rite ) they may have suggestions for your area. Their number is 800-831-7133.
Is this good for a 30,000 - 35,000 gallon pool?
Yes this filter has sufficient surface area for that sized pool. You just need to confirm that the gallons per minute rating with your model pump for your pool is compatible with that model filter.
I made a mistake on my original question, I actually need the information for the right part number for a STA-RITE Modular Media Filter - Model # S7M120. That would be for all filters to include, large and small cartridge and the air bleed filter. Also nee to know if you sell the o-ring clamps for the clamp assembly?

What material is inside the starite system 3 model S7M120? Is it corrosion resistant also for salt water?
Hi Helga, The internal and external tank for the Sta Rite System 3 S7M120 filter are constructed of glass-reinforced composite resin. This is a corrosion resistant tank ideal for salt water pools but not for ocean water as ocean water has a salt concentration which is 10 - 20 x's more than a standard salt pool.
Does this come with the filter cartridge and gauges?
This filter comes direct from the manufacturer and includes the cartridge and gauges.
(5 out of 5 stars) Fabulous Filter System
Reviewed By: hauss from Sacramento, CA ()
Pros: Easy to clean, easy to install
Cons: none so far...
It's a fabulous filter system, the pool was sparkling again within a day or two. Very easy to install and to keep clean. Inside filter can be removed for cleaning. While leaving the larger outside filter in the container you can simply hose off in there and not have to worry about lifting it out. There is a very large drain plug that you can remove to let all the dirt and debris out. The clamp system is so much easier than having to deal with the ring system.
