Hi Trouble, Thank you for your question. To remove the seats and springs from your model 2131 faucet first shut off your water supply to the faucet. Pry off the hot/cold buttons on top of the handle to gain access to the screw holding on the handle. Remove the screw and the handle. Next unscrew the bonnet nut holding down the stem assembly, it will unscrew counter-clockwise. Once the bonnet nut is removed pull up on the stem assembly to remove it from the valve body. The seats and springs will be located in the valve body directly underneath the stem assembly. Use a small screwdriver to remove the seats and springs.
Here is a link to the parts breakdown of the model 2131 to help with your repair.http://www.deltafaucet.com/customer...
