Frequently Asked Questions
What is a front access skim filter?
A front access skim filter combines a surface skimmer and a cartridge filter into a single sidewall-mounted unit. It draws water from the surface of your spa to capture debris and passes it through a cartridge filter before returning it to the tub. The "front access" design means the basket and cartridge can be removed and cleaned from the front of the unit without tools.
How often should I clean or replace the 510-1600 filter cartridge?
The filter basket should be cleaned every 1–2 weeks depending on usage. The 10 sq. ft. filter cartridge (Waterway part #817-0010) should typically be replaced every 3–6 months with regular use. More frequent bather loads or heavy debris may shorten the replacement interval.
What replacement cartridge does the 510-1600 use?
The 510-1600 uses the Waterway 817-0010 skim filter replacement cartridge (10 sq. ft., 4-1/4" outer diameter x 4" length). Contact Western Tub and Pool to order a compatible replacement cartridge along with your skim filter assembly.
Is this the same as the 510-1500 or 510-1650T?
No. While they are part of the same Waterway front access skimmer family, they are different parts:
- 510-1500 — Square spa skimmer only (no cartridge filter)
- 510-1600 — Square spa skim filter with 10 sq. ft. cartridge (this item)
- 510-1650T — Square spa skim filter with 20 sq. ft. dual-cartridge capacity
Always verify your part number before ordering.
