How far are you opening the faucet? Does it do it with a faucet wide open? Sounds like the pump flow capacity is exceeding the rate of discharge from the faucet. That pump has a 4.5 GPM capacity and will definately short cycle when using the shower. Adding an accumulator will solve that problem.
Yes, I have a 2 gallon residential expansion tank. It stops the short cycling, holds enough for a few nightly potty runs w/o the pump, and as a bonus it cut down the annoying burst of hot water when taking a Navy shower.
