We had to call a roto rooter plumber for our bathroom faucet (tub area). Apparently the knob got loose and we couldn't turn it to stop the flowing of water, unless we do it from the main water pump. The service that the roto rooter plumber did was good. He worked really fast and was friendly and professional. The only thing is that roto rooter is pretty expensive compare to other plumbers. However, the service is quick and good.
