What you need to keep your pump in top shape

These check valves are super important, they make sure that water flows in one direction inside the pump manifold. But when they get worn out or broken, that's when the problems start - pressure loss, surging, water leaks... all the things that can really knock your pressure washer out of commission.

What to expect from this kit

This is the perfect solution when you need to tackle common pump wear issues. With this kit, you'll be able to easily swap out the old valves for some new ones, and it'll sort out all the problems that have been holding your pressure washer back.

Performance and Compatibility

This valve kit is the same quality and does the same job as the OEM part number AR1828. It fits perfectly and seals just as well - it's a drop-in replacement. And it's going to work with loads of different Annovi Reverberi (AR) pump models. We've got a list of them all: RKV Pumps (18mm) series, RKV3.5G30AD-F24, RKV3.5G40HD-F24, RKV4G37D-F24, RKV4G40HD-F24, RKV4.5G32D-F24, RKV4.5G37D-F24, RKV4.5G40HD-F24, RKV5G40HD-F24, RKV5.5G40HD-F24, and the RRV series: RRV3G36D-F24, RRV3.5G36D-F24, and RRV4G36D-F24.
