Each time I get a new kitchen faucet, the water pressure is fine but within 6 months, it reduces to 1/3rd of the pressure. This has happened three times. Three separate plumbers have no explanation. The water pressure in the rest of the house is fine. I won't be able to fix this myself, but the community may help give me some ideas that I can provide to the next plumber. I'd rather not keep purchasing new kitchen faucets every 6 months and have them installed to keep my water pressure up.
