Installed on my Grand Design fifth wheel and works perfect. I can run the water without the pump kicking on for a long time. Works well with my on-demand water heater and no more pump cycling on and off when the tap is turned on low. Don’t waste you time on the cheap, small plastic accumulators. I had one of those before this one and there is no comparison.

We enjoy the performance of the tank on our regular RV trips boondocking. Life (pump) saver!
We purchased 2nd tank and installed it under our bed. Please do not judge the mess we uncovered under the bed - it looks gazillion times better compared to how we found it to be. We had to build a "platform" out cedar 1.5x4 boards to lift it up above wires, etc. A bit of back and forth - it was all done in about 20 minutes. Sits nicely below our pullout drawer. Definitely had to reduce the pressure in the tank down to about 25 psi - it filled-up the tank about 1/2-3/4 full. Plenty enough. This one is serving bathroom/shower specifically. Whereas the prior we installed was in the kitchen.
The image with tank up against the wall is in the kitchen location (next to water filter) - our 1st tank installation.
Original Review:
This is an excellent product and comes well-packaged. No surprises there. Installation was a breeze - 1/2" male threaded in (with a Teflon tape), connected with push-to-fit fittings into 1/2" PEX - all set.
We added a shut off valve into our set-up. Additionally, our pressure was about 30 PSI, so at first (it came pre-charged with over 30 PSI) it did not fill the tank at all. So, we kept reducing the pressure down to about 18 PSI and it filled-up the tank quite well. Ran the tests via faucets - pump is quite. Depleted the tank - the pump kicked in.
Two things to mention:
1. When it arrives - do not use a box cutter to open up the top - we end-up "scoring" ours with a fine scratch by cutting the packing tamp at the top of the box. Just cut on sides, lift the top a bit and then cut it.
2. If you are not seeing the results - measure your existing system PSI pressure. Unscrew the black plastic wide "nut" at the other end - reduce the pressure about 4-5 PSI lower than your existing system. Than it will work.
Hope this helps others. Some of the negative reviews mentioned that there was "no change" - they just need to drop the PSI pressure for the bladder in the tank.
Excellent product! RECOMMEND!

I recently purchased my first RV and was a bit surprised at the pump operation. It cycled continuously during use and pulsed the water. Not only is it loud and bad for the pump, it's just annoying overall. Basic plumbing makes it pretty shocking that this is set up without a pressure tank. I looked around and found this tank is about as big as I could fit in my fresh water tank area so I got it. I have a shurflo 4008-101-A65 pump which is pretty standard on a lot of RV's. Pump turns on at 38 lbs and shuts off at 55 so I inflated the bladder to 35 lbs as per the manufacturers instructions. Now the water system works like it should. Way quieter, smooth water flow and drastically reduced pump cycling. A huge upgrade for a very low price.JohnnydBig positive difference.
