Review on Delta Faucet RP25513 Stem Assembly by Jae Newton

Very easy to install. If necessary, find documents for your device. If you don't have it, then it's pretty easy. First turn off the water supply under the sink or in the house. Open the hot and cold water valves to relieve residual water pressure on the hot and cold sides of the unit. Take away your pen. Remove the large lock nut. Remove the cartridge, pay attention to the orientation before removing. Replace the spring and gasket while they are separated at the bottom so you don't have any drips. If you decide not to replace the cartridge, make sure it is installed correctly before installing a new cartridge. Reinstall the nut and re-tighten without over-tightening. Turn the water back on when the handle is properly aligned. Check for leaks again. Here it is in brief.
