A while ago I had a "professional" contracted through a major company install a hot water heater in the basement: well the hot water heater works fine but the "professional" managed to turn the water pressure to my kitchen sink to a low trickle coming out of the hot water and a slightly more stronger flow from the cold. I cannot run my portable dishwasher let alone do too many dishes at once. I use to have great water pressure before this guy came along. I have checked both dials under the sink and they are all the way turned up..... I do not know exactly what this man did; all I know is he had an attitude problem, wrecked my front screen door, and left a mess in the basement.
My house was built in 1958 but before I moved in they did some major renovations including all new plumbing (minus the hot water heater).
Can anyone tell me what I need to do to turn the water pressure up to my kitchen sink so I can run my portable dishwasher?
Please let me know what other information I can provide that would help solve the problem if need be.
