Keep your Watts 919QT reduced pressure zone (RPZ) backflow preventer performing at peak efficiency with the Watts 0888141 Rubber Parts Kit. Designed specifically for 3/4″ 919QT assemblies, this genuine OEM kit provides all the critical elastomeric components needed to restore proper sealing, check valve function, and relief valve operation during routine maintenance or annual inspection.
Why Replace Rubber Parts?
Over time, the rubber seals, diaphragms, and O-rings inside a backflow preventer are subject to wear from water pressure, temperature cycling, and chemical exposure. Degraded elastomers can lead to failed backflow tests, cross-contamination risk, and costly system downtime. Using genuine Watts replacement parts ensures a precise fit and restores the assembly to original factory performance specifications.
