Since my original post got closed down:(, I think I have come up with game plan! I will keep the existing 4048 SureFlo, add a couple feet of 1/2 flexible high pressure hose on the downstream side of the pump to quiet the little rascal. Also thinking I could add a small SureFlo Accumulator Tank to try and smooth out the pulses as we use the faucets on low flow to save water when we are boon docking. Then on the deluxe side of things I think I would like to add a second accumulator tank between my under sink filter and the filter faucet. Does anyone see any issues with installing a second accumulator on the dedicated filter line?Thanks!

What purpose/benefit do you think 2nd accumulator tank would provide?1st accumulator tank is going to be handling the whole rv plumbing system as it is installed on discharge of pump (which feeds cold and hot systems)

Why did the original get closed? Assuming this is a noise issue? Add a coil to BOTH sides of the pump, and cover them with 1/2" foam pipe covering with the adhesive closure, and add a few zip ties to keep it closed. Ours is so quiet we can't hardly hear it running

Adding more hose to the intake side will have little impact.

To winterize, I used to just close that one "extra" valve after draining the system and no extra antifreeze was needed. Now that we very rarely need to winterize, and then only for short periods, I just blow out the lines with compressed air.Accumulator tanks cut way down on the number of on/off cycles the pump goes through, extending the life of the motor. They also smooth out the pump pulses before they reach the fixtures, which can reduce noise issues caused by pipes vibrating and water hammering.
