Flojet 20028-061 Valve Chamber Kit, EPDM
The Flojet 20028-061 is the genuine EPDM valve chamber kit, carried under the factory designation "Kit V/Chmbr Ep Com 1BP". It renews the check valves that convert the diaphragm’s motion into flow in a single direction.
It is worth understanding how quietly a set of check valves fails, because it explains why so many pumps are replaced when they only needed a valve kit. Nothing breaks. The valves simply stop closing completely — hardened by age, set into a permanent curve, or nicked by a piece of grit. Each stroke then pushes a little water backwards as well as forwards, and the effect compounds: less flow, longer run times, more difficulty reaching cut-out pressure, and eventually a pump that cycles with no tap open because it can no longer hold what it has pumped.
EPDM is the compound for hot water, steam, alkalis, caustics and dilute acids, and it resists ozone and weathering well. It is not the choice for petroleum products, which swell it quickly. Fit the kit complete, inspect the seats for scoring while the chamber is apart, and clean or renew the suction strainer if the old valves show cuts — new valves in dirty water have a short life.

Frequently Asked Questions
Q: Is it worth fitting a valve kit rather than a new pump?
Very often, yes. The motor, housing and diaphragm may have years left in them, and valves are the component that wears first in most installations.
Q: How long does fitting a valve kit take?
On most of these pumps it is a straightforward job with a screwdriver — the chamber comes off the top of the pump and the new one goes on. Keeping the screws organised is the main discipline required.
Q: Should the pump be flushed before reassembly?
Rinsing the chamber and passages through is worth the minute it takes. Debris left behind from the old valves will find its way straight onto the new seats.
Q: What torque do the chamber screws need?
Firm and even, working around the pattern rather than tightening one fully at a time. Uneven clamping distorts the chamber and is a common cause of a rebuild that still leaks.
