My kitchen faucet has very little pressure and 'Bangs' when you turn it to hot. It does get hot but I have to turn the handle just right to get a little more pressure from it. When I initially turn the hot on, the pressure is fine but slowly as it gets hot the pressure slows to a trickle and starts to pulse/bang. Other rooms are fine, just the kitchen faucet. House is new (4 yrs) and we have copper up to the house with I believe PVC piping inside the house. The faucet is a Moen and is 2 yrs old and is a single handle type.
