McCann's Big Mac Soda Carbonator E Series 115v Model E400397

Worked as expected to replace a broken carbonator.

This machine makes a reality the impossible marriage of holding together a gas and water at room temperature by high pressure. It took me 2 hours to install my first toy, after that day, all my family drinks Seltzer water with the unlimited supply, this machine can make 100 gallons per hour. We go through 2 gallons per day only. A CO2 tank of 10 pounds, lasted about three months before it need charge of $12.00. By the way, one of my b es st projects ever. We can also add Sodastream syrups and have soda on tap.

...or quality control is absolutely abysmal.The 1/8th inch water supply nipple is not only about 4 threads deep, it's also made out of plastic. it immediately started leaking when I applied water to the pump. Turns out, the nipple was cross threaded. Had to swap it with a brass nipple at the extraordinarily high cost of $2.71. /sarcasm. Curious of what diversity hire engineer thought a 4 thread deep plastic piece that could see upwards of 60PSI was a good idea.Regardless, the pump doesn't seem to move water under pressure. When there is no pressure on the tank, water flows into the tank even with the pump off as it should. However, when there is pressure on the tank, the pump cannot overcome the tank pressure to pump water into it. Yes, while plugged in and running. And we're talking only ~ 80PSI of CO2 pressure on the tank.Hoping I got a bad unit/pump, will return this unit and try it again with a different unit.In case you're considering this unit, make sure you get 3/8 JIC SAE fittings an not standard 3/8 hydraulic JIC fittings. There is a small size / thread difference.
