I have an every second drip coming out of the spouts on each of my two showers which are about 10 years old. I have been told by a plumber that its a $1700 job(Yeah Ok!!!! ) or a simple project i can do for less then $20. From what was explained to be i have the lever that turns on the water that curves up for hot and down for cold and that is where the leak is from(the diverter). I was told to shut off the water, remove the part(what part??) and bring it to a plumbing supply store and they will give the part. This advice was from several differnet people so i wanted to get your take on it. any assistance would be very helpful. Thank you
