I am a home service technician, and I recently completed a job that involved installing an RO system and a new faucet in a customer's bathroom. The customer provided the RO system and the faucets, and I installed them according to their specifications. First, I installed the RO system by replacing the chrome s trap with a pvc s trap and installing a shutoff valve and supply line on the cold side. I then removed the old bathroom faucet and pop-up assembly and installed a new faucet directly to 1/2" copper pipe. The customer did not want to cut a hole in the wall, so I did not add new shutoffs. The pop-up assembly that came with the faucet was too large for the hole in the sink, so I went to the supply house and got a slimmer pop-up assembly with the click stop. I tested these and both are working well with no leaks at time of service. Overall, the job went smoothly, and the customer was satisfied with the results.
