ROBERTSHAW-25471-D1-Membrane en caoutchouc

No complaints
Installed it on our older Robertshaw unit and it’s running smooth again. Held pressure just fine. Easy swap. Job done.

Works well but packaging was basic
Diaphragm itself is solid, no cracks or imperfections. Just would’ve liked a bit more protective packaging, came in just a plastic wrap.

Exact fit, no hassle
Used this as a direct replacement - fit perfect, no leaks. Feels like good rubber, not the cheap stuff. Shipping was fast too.
