Review on 💧 Enhance Water Efficiency with Delta RP62734 Handshower Flow Regulator Washer - 1.5 GPM by Tina Wells

(ordered 2) Poor quality. I went to install them and one of them failed with the outer rubber ring snapping into place. When I installed the second unit, which took a week, the kids complained that the water pressure started up again. The found rubber ring of the second block also let go, and the adapter ring went into the shower head. Now I'll have to try another type that bolts to the shower head, or maybe just order a new shower head (since I can't get that plastic disc out). I will say that the water pressure before the rubber failed was exactly what we wanted, but for the money spent I would estimate it would last at least a year or two.
