- Delta two-handle tub and shower faucets that used RP25513

- Delta RP50587 or RP19804 cartridges
- Pre-2006 two-handle stems (RP1740 pattern)
Is this your part?
Pull the handle and the bonnet nut and lift the stem out. The RP25513 stem is just under 2 in. tall with a splined polymer broach, and a small rubber seat cup and spring sit under it in the valve body. Faucets built before 2006 take the RP1740 stem, which has a different broach.
When to replace it
The spout drips with the handle closed, water weeps around the handle base, or the handle has gone gritty or loose. The stem, seat and spring cause nearly every two-handle Delta leak, and all three are in this kit.

Questions
Is there a 2 pack?
Yes. A 2 pack for rebuilding both sides is sold on Amazon.
Do I need to buy RP4993 seats and springs too?
No. The seat and spring are in this kit.
Why does my handle turn backwards?
The quarter-turn stop is set wrong. Check the stop position for the hot and cold side.
