Description
If your pump isn’t drawing any water in or the flow is irregular you may have a check valve issue. The springs can become corroded and gummed up or it is possible the valve seats are pitted. The 9910-KIT1987 will replace all four check valve assemblies as well as the o-rings to create a seal to have your pump back up and running.
Hypro/Pentair is no longer distributing the 9910 series of diaphragm pumps, components, and related parts. Products with Hypro labeling will be unavailable soon.
