Ratings and Reviews for  Ideal Standard Pneumatic Dual Flush Valve 1.5" EV98167

An excellent quality outlet valve. To replace the unit, disconnect the two pneumatic hoses and then simply push down and twist the valve in an anticlockwise direction to unlock it from its seating basket. It is possible to purchase the outlet valve service kit SV01967 and pneumatic diaphragms SV70367 separately, but I find for the difference in cost, it's easier and quicker simply to replace the whole unit.

Replaced our original ones so will probably last about 7 years of heavy use. They are installed in a busy office and have a lot more use than a domestic property.

It works.

Exactly the same as the one I was replacing.

Good price.
