I bought new kitchen faucets and after they were installed there was never much pressure. I thought it was because I installed a circular sensor valve and that it was causing the low pressure and would until hot water was installed. However, installing the hot water system did not improve the pressure. The pressure at the pipes and hoses is terrific, but the water trickles out of the tap on any setting.
