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.

The tanks hold 24 oz. at full pressure, and only a fraction of that at zero pressure. You have zero pressure in a winterized trailer.

I used coiled 40" soft shower head hoses and foam pipe insulation connected to our pump's inlet and outlet to drastically quiet it down. The hose on the inlet side dampens mechanical pump vibration transmission to the hard pipes, while the hose on the outlet side dampens both the mechanical and water pulsing vibrations. Now our pump can only be heard as a soft hum in most of the coach if everything else is silent. Certainly the hose on the outlet side was the most effective, but the one on the inlet side added enough additional reduction to make it well worthwhile as well.

IF the pump intake is hard wall PEX but in most instances it's already soft wall braided hose, ergo the reason that adding more does little.

40" and 15 feet of coiled hose? Sounds like over kill if you ask me. My 2' loop works perfectly. I can hear a hum in the middle of the night with no sounds outside and no one moving around but otherwise, it's pretty quite.

Because of the particular type of Filter set up I have there is a lot of restriction between filter and the small faucet. I was just thinking that the second accumulator tank would make a smoother flowing filtered water flow.
