Description
11872 Dual Split Hose Plunger Valve for Above Ground Pool Pumps
The iFJF Dual Split Hose Plunger Valve is a direct replacement for the Intex 11872 valve used in above ground pool filtration systems. This two-hose valve controls water flow between your pool and pump, allowing you to stop water flow for maintenance without draining.
How It Works
The dual split design connects to two hoses simultaneously — typically the pool-to-pump inlet and the pump-to-pool return. The plunger mechanism pushes down to seal (closed position) and pulls up to open — giving you quick, tool-free flow control when you need to clean the pump basket, change hoses, or winterize the system.
Key Features
-
Dual Split Hose Design: Connects two 1.25-inch hoses simultaneously — simplifies plumbing setup
-
Push-Pull Plunger Operation: Quick, easy flow control without tools
-
Leak-Proof Sealing: Precision-molded plunger and O-ring design prevents water bypass in the closed position
-
UV-Stabilized Construction: Withstands years of sun exposure without becoming brittle
-
Direct Intex Replacement: Cross-references with Intex 11872, 25080RP
Installation Tips
- Ensure the O-ring is properly seated and lubricated with silicone grease for smooth operation
- Do not overtighten hose clamps — snug plus 1/4 turn is sufficient
- Test the valve before filling: push down to the closed position and verify the plunger seats fully
- If the plunger is stiff, a small amount of silicone lubricant on the stem restores smooth operation
FAQ
Q: How does a dual split plunger valve work?
A: This valve controls water flow to/from your pool pump. The plunger mechanism pushes down to seal and pulls up to open — allowing you to stop water flow when cleaning the pump basket or changing hoses.
Q: Will this stop water from draining when I remove my pump?
A: Yes. Push the plunger down to the closed position before disconnecting the pump — this prevents the pool from draining through the hose.
Q: Is this a direct replacement for Intex part 11872?
A: Yes. This is a direct replacement valve manufactured to the same specifications as the Intex 11872 dual split hose plunger valve.
Q: What hose size does this fit?
A: Designed for standard 1.25-inch diameter pool hoses. Compatible with both Intex and Bestway above ground pool systems.
