I installed a tankless water heater and now the kitchen sink has low pressure.
I checked the aerator and cleaned it out, still low pressure. I filled a container with water with the aerator both On and Off of the hose, 47 seconds to fill with aerator on, 43 seconds to fill with it off.
Need some advice on where else to check - other than about the aerator, please.
**used PEX tubing and shark bite unions for new water heater. Connected back to main water lines (cpvc).
