Why is my Raypak RPSFP16 Water Filtration Systems pool water cloudy?
- T
  Theresa CarlsonAug 21, 2025
  Cloudy pool water in Raypak Water Filtration Systems can result from a dirty sand bed needing backwashing, incorrect sand needing replacement, algae build-up from poor water chemistry (adjust chlorine), or a calcified sand bed due to poor water chemistry (adjust pH balance). Heavy swimmer usage may require more frequent backwashing. An incorrect pump flow rate may require adjustment or pump replacement. Short backwashing cycles should be lengthened, and undersized backwash lines should be enlarged.

How to fix Raypak RPSFP16 Water Filtration Systems filter leaking water?
- D
  Daniel WebsterAug 22, 2025
  If your Raypak Water Filtration Systems sand filter is leaking water, the tank might be cracked (requiring replacement), the drain plug may not be tight (re-tighten it), or the valve to tank O-ring could be damaged (requiring replacement).

What to do if Raypak Water Filtration Systems pump delivers no water?
- R
  Richard DavisAug 25, 2025
  If your Raypak Water Filtration Systems pump delivers no water, it might not be primed, so prime the pump. Also, check for closed valves in the suction or discharge line and open them. Leakage or air in the suction system may require a plumber. A clogged impeller requires pump disassembly to clear the obstruction.

Why is there high pressure in my Raypak Water Filtration Systems filter?
- K
  Kelly NelsonAug 27, 2025
  If you have high pressure in your Raypak Water Filtration Systems filter, backwash the filter. If the sand bed is calcified due to poor water chemistry, adjust the chemistry (pH balance). If the return lines are too small for the pump flow rate, increase the pipe size.

How to stop Raypak RPSFP16 Water Filtration Systems sand entering the pool?
- C
  cherylhansonAug 27, 2025
  Sand entering the pool from Raypak Water Filtration Systems may be due to sand that is too small, requiring a change of sand. Alternatively, the pump flow rate may be too high, requiring adjustment. A calcified sand bed due to poor water chemistry requires a chemistry adjustment (pH balance). Other causes include a broken lateral (repair), a loose center-pipe (re-tighten), too much sand in the tank (reduce sand level), an incorrectly positioned multiport valve (reattach correctly), or too much air in the filter (purge air).

Why is my Raypak RPSFP16 pump and motor noisy?
- P
  Paul GomezAug 29, 2025
  If your Raypak Water Filtration Systems pump is noisy, the basket in the skimmer or hair in the lint strainer may be plugged, so clean the basket. Also, worn motor bearings may require you to replace the pump. A partly closed valve in the suction line requires readjustment, and a partly plugged suction line needs cleaning or removal of the plug. A plugged or too-small vacuum hose also needs cleaning or removal of the plug. Ensure the pump is properly supported and examine or replace the base if needed.

What to do if Raypak Water Filtration Systems motor does not start?
- A
  amooreAug 31, 2025
  If the Raypak Water Filtration Systems motor does not start, ensure the switch or circuit breaker is in the ON position. Replace any blown fuses. If the motor shaft is locked, the motor windings are burned out, or there's a defective starting switch, replace the pump. Repair any disconnected or defective wiring. Low voltage requires calling an electrician.

How to fix Raypak RPSFP16 multiport control valve leaks?
- K
  Katherine HortonSep 2, 2025
  If the Raypak Water Filtration Systems multiport control valve leaks, ensure the handle is properly located in the selected setting by re-assembling correctly. Damaged O-rings (valve to tank, valve cover, or pressure gauge) require replacement.

Why is sand coming out of the Raypak RPSFP16 waste line?
- D
  Derrick GarciaSep 4, 2025
  Sand coming out of the waste line in Raypak Water Filtration Systems may be due to a pump flow rate that's too high, lifting sand too high during backwash. Adjust the flow rate or change the pump as needed.

Why is there low pressure in my Raypak Water Filtration Systems filter?
- M
  Michael FranklinSep 6, 2025
  Low pressure in your Raypak Water Filtration Systems filter can be caused by an incorrectly set multiport control valve, which requires re-assembly. If the pump flow rate is too slow, check the speed and control valves. An air leak in the pump suction requires checking the seals and tightening as needed.
