Good morning all I have kind a strange question and not sure if I can describe it properly. We have a 3 month old Coachmen Apex Ultra light 215 RBK. We have one issue that drives me crazy (ok may be a little bit picky). When we are hooked up to water, the and you turn on a faucet the water runs smoothly. But when we are using the pump it pulses more so on the hot side than the cold except the toilet. I have owned 4 TT and never noticed to this extent the problem. Any thoughts on what could be wrong or if you have encountered this before what did you do.
