### ⭐⭐⭐⭐⭐ Worth the extra few bucks over the off brand
*by H***T on June 6, 2026*

### ⭐⭐⭐⭐⭐ Easy System Upgrade
*by T***N on July 14, 2026*

Works as advertised, easy install, reduces pump noise, speeds system pressure recovery …recommend

### ⭐⭐⭐⭐⭐ Much quieter now!
*by T***N on June 7, 2026*

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.
