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.

worked as designed.
Did the job. Added it to the boat fresh water system, the pump noise is too quiet now, hard to tell if it is running. Should have bought the 1l version but space was an issue. Functions right out of the box for us.

Quieted down my pump and reduced pulsing at low pressure
Smoothed out water flow. Really easy to install and tune properly. Make sure to set it roughly 3 psi below your activation pressure. Keep in mind that while it can be mounted in pretty much any orientation, it is best to keep the inlet and outlet on the bottom such that it will drain and not retain water so that it can be winterized properly in an RV setting.

Great addition to pump
This is my second pump and bladder tank purchase. Love them. They work well together and the addition of the bladder tank. Slows the pump down to where it barely runs. Makes things quieter and keeps the pressure steady

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.

Good addition to our camper
I installed this in our camper to keep the demand pump from running as often. I think it cut the pump cycles in half.

Good pump and we are pleased with purchase .
We were pleased with it after the seller paid for a part that was damaged when we received Pump.

Lasted two months past warranty before bursting
This pressure tank worked great all the time I had it, smooths out the pump pulses perfectly. However, this evening I was sitting at the counter top that the pump sits underneath in my RV and started hearing a high pressure hiss. Found out the bladder on the pressure tank just gave way and sprayed water all over my camper. Looks like it's had a slow leak for a little while too so have some mold and water damage to deal with. It did last past the 2 year warranty period but not any longer. I was happy with it during that time but I might look for something with a longer service life next time.
