Makes a difference in water flow
Does what it says, relatively easy to install. It really works and was easy to add to my existing seaflo pump

Worth the extra few bucks over the off brand
Does the job , definitely helps, the off brand i had previously only lasted a few months, that's why I've waited almost a year to review this. Has worked well the whole time. Not complaints

Eliminated surging and reduced pump cycling
This tank coupled with a new water pump (no special pump, normal on/off shurflo without variable speed) accomplished several things. Water pump cycling markedly reduced, water flow surging with low faucet flow (pump cycling on and off repeatedly) basically eliminated, smooth flow all the time. Sounds levels cut way down, not sure though how much of that is from adding this tank and how much was a combination of new pump and rerouting the water lines to eliminate right angle fittings at the pump.

Exactly as Advertised
This pressure tank is installed in my motor home. Campgrounds do not provide enough water pressure to operate my tankless/on demand water heater which requires 50 # of pressure. This gets the job done! And, it quiets my water pump and the pump does not cycle as often/long.

Solved water pump hammer on a boat
Straight forward installation. Decent quality. Solved severe water hammer issue that was noisy and bad for the system. The pump runs less, is quieter and the flow has smoothed out.

Much quieter now!
I put a 20-in premade supply line from Menards in a loop from the water pump discharge to one side of the accumulator. The water line that used to connect to the discharge side of the water pump is now connected to the other side of the accumulator. I mounted the accumulator vertically on a strip of plywood that I installed across the plywood sides of our water heater area. Our water system is under the couch on the inside of our Jayco Flight camper. I left the accumulator factory pressure of 10 lb alone for now and tested the system after install. I already had the flexible reinforced lines on both sides of the pump, but this accumulator really did the trick. The pump and PEX lines are now unbelievably quiet compared to the hammering that was transmitting through the lines before the accumulator installation.

The pumps work
These pumps are great, I live in Mexico and the 'water system' in my house is gravity fed. Not ideal at all, you had to do laps in the shower to get wet. No more. I get excellent pressure now from the shower and the taps, it was, in the shower, cycling the pump a little so the flow wasn't consistent but even at the slack flow it was more than enough. I ended up buying an accumulator tank and that solved the 'problem' that wasn't really a problem in the first place immediately. Worked so well I bought one for a friends house and they absolutely love it... I think neighbors are going to the house to witness the miracle of water pressure from their taps and shows, kind of like the Fatima deal. Well, maybe not quite on that scale but people are impressed. Great products, seriously, easy peasy to install and they have a most excellent warranty, 4 years. Plus the price.. to be honest I wasn't expecting much considering how inexpensive they were but.. far exceeded my expectations. If you have a problem with low water pressure in your house, in your trailer or on your boat this is the solution. 5 stars for both the vendor and the product.

Be prepared to buy your own fittings.
The tank is great in that my pump doesn't have to start every time I draw a little water. Pump hasn't come on in the middle of the night. However, I had issues with water spraying out of the connectors that were included. I tried to tighten them up but no luck. I ended up purchasing proper NPT couplers and fittings and don't have any leaks now.

A great addition to have.
This little gadget help keep the pressure up and helps the pump work less.
