About the Hayward ProSeries side-mount sand filter
Hayward's ProSeries high-rate sand filter owner's manual (IS210S1 Rev A) covers models S210S, S244S and S310S with one replacement parts list. The VariFlo control valve connects to the tank through top and bottom elbow assemblies and bulkhead fittings.
The tank, elbow assemblies, laterals, lateral holder and air tube differ by model; the S310S also has its own flange clamp and stand support. The air relief, dome, diffuser, drain cap, gauge, seals and o-rings are shared.
Common problems and the parts involved
Low water flow
Hayward's checks: skimmer and pump strainer baskets clear of debris, no restrictions in the intake and discharge lines, no air leak in the intake line (bubbles returning to the pool), then backwash the filter.
Parts: . Troubleshoot this
Short filter cycles
Hayward's checks: look for algae and superchlorinate as required, keep chlorine and pH in range, and check the surface of the filter sand for crusting or caking (remove 1 in of sand if necessary).
Parts: .
Pool water won't clear up
Hayward's checks: chlorine, pH and total alkalinity adjusted as required, enough flow through the filter, longer run times, and the Vari-Flo valve set to Filter.
Parts: .
Repair or replace?
Most of these parts are replaceable on their own, which is why it matters which one has actually failed before anything is ordered. Whether a repair or a new pump makes more sense depends on what failed and the condition of the rest of the pump.
