Low Pressure - Hot Water in Kitchen Faucet Only
Just moved into a new house that was built in the late 80's. We've got forced hot water heat (via natural gas boiler) as well as a SuperStor hot water tank. Great water pressure throughout the house with the exception of the hot water in the kitchen faucet. I cleaned out the aeroter on the faucet and replaced the flexible hose that connects to the hot water supply under the kitchen sink just to be safe but it didn't make a difference.
Here's where it gets tricky, I turned off the output from the SuperStor, where the showers/faucets get their hot water from. Kitchen faucet still has hot water at that point with same low pressure but (rightfully so) there is no hot water elsewhere in the house. That means that the hot water for kitchen faucet is probably fed off the forced hot water system for the heat. At this point, I'm at a loss. I have some plumbing skills but playing around with the forced hot water system is a little above me. Anyone have any ideas on how I get better pressure to the kitchen faucet?
