Review on 🚿 Delta RP19804 Pressure Balance Shower Cartridge Assembly Replacement for 1300/1400 Series Tub and Shower - Fits Delta Select Monitor Valves - 1 Piece by Quinton Wonsley

In less than 2 weeks only warm water came out of the tap, although the temperature control was adjusted several times. When removing it, I found that the equalizing valve was stuck where mostly only cold water flowed. Factory valves, both parts of this valve are metal, this valve has a metal piston and a plastic sleeve. When sliding back and forth, the plunger gets stuck at both ends of the sleeve.
