Swimables SW-28-588 Jandy-Style Drain Plug Replacement – Replaces R0358800
Restore a Proper Seal When Draining Pool Equipment
The Swimables Jandy® Style Drain Plug (SW-28-588) is a replacement drain plug designed to replace Jandy OEM part R0358800 on compatible pool filters and equipment housings. Drain plugs play a critical role in allowing controlled draining of pool equipment while maintaining a watertight seal during normal operation.
A cracked, stripped, or missing drain plug can cause slow leaks, air intrusion, or complete loss of prime. Replacing the drain plug is a simple but essential repair for keeping pool equipment sealed and operating correctly.
This product is a pool equipment drain component, engineered specifically for swimming pool systems.
What a Pool Drain Plug Does
Drain plugs are installed at the lowest point of pool equipment housings to allow water to be drained during:
-
Winterization
-
Equipment service or repair
-
Filter cleaning and teardown
-
Freeze protection procedures
When properly installed, the drain plug seals tightly during operation and removes easily when draining is required.
Jandy® Style Replacement for OEM R0358800
The SW-28-588 drain plug is manufactured in a Jandy-style configuration and designed to replace OEM part R0358800 used on select Jandy pool filters and equipment.
This part is commonly serviced alongside components found in the Pool Filter Replacement Parts Collection and Pool Plumbing Components Collection.
Always confirm OEM part number and equipment model before ordering.
Includes a Sealing Surface for Leak Prevention
Pool drain plugs rely on proper sealing to prevent leaks. When the sealing surface or threads wear out, even a slightly loose plug can drip or draw air.
Replacing a worn drain plug helps:
-
Stop slow leaks at the equipment base
-
Prevent air from entering the system
-
Maintain stable pump prime
-
Protect surrounding equipment pads
This small part plays a big role in overall system reliability.
Common Signs a Drain Plug Needs Replacement
A failed or damaged drain plug may cause:
-
Dripping water from the bottom of the filter or pump
-
Air bubbles entering the system
-
Difficulty tightening or loosening the plug
-
Stripped or cracked threads
-
Plug no longer sealing even when tight
Replacing the plug is often the fastest and safest fix.
Built for Pool Equipment Environments
The Swimables drain plug is manufactured from pool-rated materials designed to withstand:
-
Constant water exposure
-
Chlorinated and saltwater pools
-
Pressure changes inside filters
-
Seasonal temperature swings
This ensures dependable sealing performance over time.
Ideal for Service Calls and Seasonal Maintenance
Drain plugs are commonly replaced during:
-
Filter rebuilds
-
Seasonal equipment inspections
-
Winterization service
-
Leak troubleshooting
Service professionals often keep replacement drain plugs on hand because they are inexpensive and frequently needed.
This part pairs naturally with filter O-rings, air bleeder assemblies, and filter manifolds found in the Pool & Spa Filters Collection.
Installation Notes
General installation considerations include:
-
Remove old drain plug carefully
-
Inspect threads in the equipment housing
-
Hand-tighten the new plug snugly
-
Do not overtighten to avoid cracking
-
Check for leaks after system startup
Thread sealant is typically not required unless specified by the equipment manufacturer.
