Zodiac / Polaris R0723100 PB4SQ Pump Body (Booster Pump Housing)
The R0723100 is the OEM replacement pump body (housing) for the Polaris PB4SQ booster pump — also sold under the Zodiac name. This housing is the main wet-end shell that encloses the impeller, volute, and connects suction and discharge plumbing. Replacing a cracked or damaged housing with the original-spec R0723100 restores proper sealing, pressure containment, and pump performance.
Key Features

- Durable molded plastic construction — resistant to pool chemicals, salt water, and typical pool operating conditions.
- Exact fit to ensure alignment of impeller, motor shaft, and plumbing ports without modification.
- Restores structural integrity and prevents leaks or loss of prime when original pump housing is compromised.

When & Why to Replace
Use R0723100 when the original pump housing is cracked, leaking, or otherwise damaged — common failure points can lead to loss of suction, air intrusion, or full pump failure. Installing the correct OEM housing restores reliability, extends pump life, and maintains safe, pressure-resistant operation under typical pool conditions.
Installation & Maintenance Tips
- Shut off power and drain pump completely before disassembly.
- Remove old housing, then clean and inspect impeller, diffuser and shaft for wear or damage before re-assembly — replacing worn parts if needed.
- Install new housing, ensuring proper alignment of plumbing unions, impeller and motor shaft to avoid stress on components.
- Reassemble and tighten bolt pattern evenly; confirm all seals and O-rings are in good condition to prevent leaks.
- After reassembly, prime the pump and test under low pressure for leaks before full operation. Inspect regularly, especially after seasonal shutdowns or chemical changes.
Why Stock This Part
Because the housing is often the only failure point when a booster pump suffers a leak or crack, offering the R0723100 allows pool service professionals and retailers to repair a pump without replacing the entire unit. This saves customers cost and reduces waste — making it a high-value, high-utility part to carry for maintenance and repair services.
