This past week we've experienced a loss of water pressure in our kitchen faucet. The faucet is only 6-months old (Moen Extensa Chrome Single Handle Kitchen Faucet With Pullout Spray). Our handyman installed it for us. The house was built in 1992 and all pipes are in good condition upon a home inspection in April 2004 when we bought the house. We have city water. All other water pressure in the house appear to be fine (other bathrooms/laundry washer/toilets). Could possibly need a new hot water heater as the hot water in the shower only stays really hot for a 15 minutes shower. This shouldn't be the case considering there is usually no other water running in the house when someone takes a shower and I would imagine the hot water heater (original one installed by homebuilder) is supposed to accommodate the size of our house (2756 sq.ft. 5 bed/3 full bath).

Back to the original question -- I've run my finger across the faucet spout (where the water comes out) and that seems to help improve the pressure temporarily for a few seconds but the it goes back to the same low water pressure. The spray feature pressure is a little better than when regular water is coming out but we still notice a diminished pressure from a week ago.

Any help on this would be greatly appreciated!
