APC Pump Repair Kit for Jandy JHP & JHPU (GO-KIT77 / APCK1181)

The APC APCKIT77 / APCK1181 Pump Repair Kit (GO KIT 77) is a complete seal and O-ring service kit engineered for Jandy JHP and JHPU series pool pumps. Manufactured by APC (Aladdin Pool & Spa), this kit bundles every critical wear component needed for a single pump rebuild — restoring leak-free performance and extending pump life without the cost of full replacement.

🚩 PRO TIP

Always replace all seals and O-rings at the same time — even if only one is visibly worn. Mixing old and new rubber components creates uneven sealing surfaces that lead to repeat leaks. Lubricate every O-ring with a pool-grade silicone lubricant (never petroleum-based grease) before reassembly.
