This accumulator is a great value. I had installed similar (more costly) accumulators on my 30ft sailboat and in my other camping trailer. The etrailer video incorrectly instructs to set the charge pressure to 3 psi. This is a mis-read of the labeled instruction on the unit which states to pre-charge to 3 psi less than the pump cut-in pressure. I set my pre-charge pressure to 37 psi for my 40 psi cut-in. I found this too much. After experimenting with a few other settings, I settled on 20 psi pre-charge which provided the minimum amount of pump cycling when running the kitchen sink faucet at various flows.


Comments
I reached out to the manufacturer and the tank does com pre charged to 10 PSI. It can be adjusted up or down using the schrader valve and a bicycle pump. I recommend viewing our second video which I have linked below.

It helped quiet the water system. Made the system work better! I subtracted one star for the fittings, they both leaked! A small o ring in the fitting fixed the leaks!

So quiet I couldn't hear it running with my music playing.

Works great, wish i had installed it so oner.

This thing is a great upgrade to our RV. Our water tank and pump is directly under our bed. It was very noisy and pulsating constantly. This tank made it almost completely quite and the pump has a longer draw down before cycling. Excellent product and I have recommended it to others.

Works great! As it should!

  • How Often Should You Check The Pressure Of Your Seaflo Accumulator Tank
    Sorry for the delay, I wasn't getting any word back from Seaflo until today. Their rep recommends checking your Accumulator Tank # SE38FR quarterly. Seaflo's Accumulator tanks have a small air bag inside of them that can lose pressure over time causing the pump to have work harder. There is an air inlet (pictured below) that you can hook a standard bike air pump onto to increase the pressure inside of the airbag.

  • Is Accumulator Tank Needed for HydroMax RV Fresh Water Pump
    If you'd like you can use an accumulator tank with the HydroMax RV Fresh Water Pump - 12 Volt - 3 Gallons Per Minute - 55 psi # P25201. It has standard 1/2 inch fittings so you can use the Seaflo Accumulator Tank for Marine and RV Water Pumps # SE38FR. An accumulator tank is not needed, but is a nice convenience feature because it makes the water pump system quieter; it traps and absorbs water and air in the tank which lessens the noise. So while it is not necessary, it is a nice thing...

  • Is An Accumulator Tank Needed For The Excel RV Tankless Water Heater
    The need for an accumulator tank like the Seaflo Accumulator Tank # SE38FR with the Excel RV Tankless On-Demand Water Heater # EX93FR would depend solely on the pressure of your water pump. This water heater requires a water pressure of 2 psi up to 120 psi to properly function. It has an operating waterflow of 1.6 gallons of hot water per minute. A pound of propane has 21,591 BTU, so with the Excel burning at 38,000 BTUs you would multiply 21,500 by the size of the tank (4gal) and divide...
