The Pentair 4002574 GRO-50EN High Efficiency membrane without drain line flow control, is an innovative next-generation reverse osmosis membrane. This RO membrane uses "Thin Layer Composite technology" (TLC) to provide enhanced water recovery in an encapsulated membrane. Where traditional RO membranes have a 3:1 ratio of 3 gallons of waste water to every gallon of purified water, the GRO-50EN new technology allows for a 1:1 ratio of 1 gallon of waste water to every gallon of purified water; making it more water and energy efficient. Less waste water down the drain for the same amount of purified water means you can save money and help the environment with the same great results.

The Pentair 4002574 GRO-50EN model RO membrane includes a permeate check valve, a 96% rejection rate, 1/4" quick connect fittings and is 2.5 inches wide by 15.14" inches long with a production rate of 50 gallons per day.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.
