Balance Chamber Assembly Kit

The Powers 900-259 Balance Chamber Assembly Kit is a replacement component for pressure balancing valves. It is designed for use with Series Models 1 and 2 for 800 and 900 valves. The kit includes the necessary parts to service the balance chamber mechanism. It comes in an unfinished finish and is a non-CEC compliant item.

Valve Service Upgrade

This assembly replaces the internal balance chamber within compatible Powers pressure balancing valves. The upgrade is worth it when the existing valve body remains sound but temperature regulation has become erratic or the chamber mechanism has failed. It restores proper mixing function without requiring a full valve body replacement. California Proposition 65 warnings apply regarding cancer and reproductive harm.

Installation Notes

Installation involves accessing the valve body and swapping the chamber assembly, a task suited for those familiar with pressure balancing valve internals. Common issues include difficulty removing the old chamber due to mineral buildup or corrosion. Ensuring the correct series model match for 800 or 900 valves is critical to avoid fitment problems. The connection size is listed as not applicable.

Questions about this item

Which valve series does the 900-259 balance chamber fit?

The kit is designed for Series Models 1 and 2 used with 800 and 900 pressure-balancing valves.

How do I install the balance chamber assembly in my pressure-balancing valve?

Shut off water, remove the valve trim and cartridge, insert the new balance chamber, then reassemble; the step often missed is lubricating the O-rings before seating the chamber.

What upkeep does the balance chamber need over time?

Inspect the chamber annually for mineral build-up and replace it if pressure balance drifts or the valve starts leaking from the body.
