ไดอะแฟรมวาล์วป้องกันการดูดกลับซีรีส์ 100 57078

Didn't realize the pack came with two different diaphragm designs, so I was worried I'd ordered the wrong one for my older valve. Turns out one of them fit perfectly and the leaking stopped the same afternoon. Handy that it covers both valve generations.

My valve was leaking for weeks and this fixed it in about ten minutes. Nice that both diaphragm designs come in the pack, since I wasn't sure which one my model took. The rubber feels thick, not flimsy like the last one I bought.

Wasn't sure which design I needed, so having both styles in the pack saved me a second trip to the store. The rubber on this one feels thicker than the old diaphragm I pulled out, and the valve stopped leaking the same afternoon.
