It's Alive

I have a Delta single handle pressure balanced bath valve (model 1700) in my shower stall that is 8 year old. The problem is that is drips water (at a fast rate) about 5-10 minutes after the shower is turned off. The dripping lasts about 1-3 minutes and then stops completely. I have replaced the seats, springs and seals and checked the cartridge assembly (shaking it and listening for rattle). It still drips. Anyone have an idea of what might be causing the dripping?

I think what your talking about is just water that is left in the lines after you turn off the faucet.
Try after your finished in the shower releasing the tub spout plunger so that the water that is trapped in the lines after you turn off the faucet can drain out the tub faucet.
