Features:

  • .75 Liter (.2 Gallon) food grade expansion tank
  • 4-Year Warranty!!
  • Increases the life of your pump and battery, while reducing sound and providing a more consistent water supply.
  • Set Accumulator ~3 PSI below water pump cut-in pressure for optimal usage
  • Connect Accumulator Tank to outlet side of water pump for best results
Easy install, works well.

Really easy to install, I just needed to get the Quick Connect fittings for the in & out. I also had to increase the air pressure in the tank as per the instructions. But it seems to be doing the job.

Seaflo Pre-Pressurized Accumulator Tank

My RV developed a leak in the water bay after fixing it I started getting a loud knocking when using the shower. I purchased and installed the Seaflo Pre-Pressurized Accumulator Tank and my water pressure is steady and the knocking is gone. They should install these in all high end RV's from the factory! Awsome!

Great product

Existing water pump in our fifth wheel trailer was connected directly to the PEX piping which was a no no. Made a lot of noise and hammering vibration when the pump ran. I installed this accumulator horizontally with a dual hose kit (from Amazon) on the discharge of the water pump. Installation was super easy. Moved the water pump about 2 inches to allow installation of the hoses. Used the pressure gauge on my small air compressor to determine the pressure when the pump starts and adjusted the precharge pressure in the accumulator accordingly. Made a huge difference. System runs smoother and quieter. With the accumulator, the pump also doesn't cycle as frequently. No leaks!

Every RV with a water heater should have one of these.

On my last RV, when the water heater was filled with cold water and it was turned on, if I didn't relive some pressure in the system the safety valve on the water heater tank would vent a little water. I was glad to discover small tanks like this so I installed it in my new RV. No more issues with a weepy safety valve. :) It is small enough that I was able to mount in under the cabinet where I can still reach the air valve for when it needs a little air added. It has rubber grommets in the two mounting holes and comes with two straight threaded adaptors to 1/2" barb fittings.

Perfect. Just what I was looking for.

I used the accumulator on my 1983 Six Pac camper. It sure smoothed out the water operation. Gives a little buffer to the system. Water pump does not cycle as much. It came with 7 lbs press, which is just below the the cut in pressure from the onboard pump. I highly recommend it for small system projects.

Works like a charm

Keeps the switch from overheating during heavy use, provides less pulse in the water flow which allowed us to install the tankless water heater.

Excellent quality tank that reduces pump cycling

I installed this tank inline with the pump for supplying water to an outside kitchen from a tank. It definitely reduces the number of start stop pump cycles. Very high quality construction. One note of caution - I used BRASS fittings on the tank and accidently cross threaded the plastic fitting on the housing. MY FAULT! If you decide not to use the supplied fittings, be very careful putting on brass fittings. I ended up buying a second tank since I messed up the first one.

Great quality and great price

This is an excellent quality RV accumulator tank. Includes two barbed fittings. You may need to purchase some clamps depending on your application. This is less expensive than the competitor's brand and ships prime unlike the competitor's which can take weeks. Search YouTube for SeaFlo RV Accumulator Tank to see a video of how to install and results. I would purchase this again.

Sturdy but small.

Be sure you want this size before you order. I did, because I just wanted some pulse control on my on-demand water pump. If you want to pump up your system and then use it without the pump running every time you turn on a faucet, get a much bigger tank. I found the best result was to have about HALF the air pressure as the max pump pressure, which reduces pump cycling compared to the recommendation that the air pressure match the pump pressure. Experiment! There's no single best pressure setting for every system.

Great accumulator. Impressed with the quality

Great accumulator. Impressed with the quality. Includes 2 barb fittings also. Solved my pulsing problem with freshwater system on boat. Previous owner had lots of leaks due to pulsing action with no accumulator. Now water flow is smooth out of faucets.
