Ellie U. ★★★★★

My zone valve kept weeping at the stem until I swapped in this diaphragm, and the shutoff is crisp again with no drips overnight. Fit was right for my 1 in. internal bleed valve, and it sealed on the first try without me fighting the bonnet screws.

William P. ★★★★★

This diaphragm dropped straight into my 3/4 inch internal bleed valve and the zone finally shuts off completely again. No more puddle at the low head, and it only took a few minutes to swap.

Emma ★★★★★

My sprinkler zone had been dribbling for weeks and this diaphragm fixed it in about five minutes. It seated perfectly in my 1 inch internal bleed valve and shutoff is crisp again. Cheap part, saved me from buying a whole new valve.
