SUS316 Stainless Steel 3/4" 0.75 inch Check Valve Spring Loaded in-line CF8M WOG1000

I was concerned about quality and tolerances but I took a chance. Happy to say they were made very precisely and I’m very picky. I bought the 1.5” in SS and three are in a 460’ well and working. I would order again without hesitation. Shipping took six weeks but they said it would be six weeks so I have no complaints. That’s all folks.

I have never seen a product of its kind, so well finished, it seals perfect, it releases immediately, solidly, inside it is observed of very good quality. I am using it to maintain pressure in the water system of my house and it does not show signs of loss. Excellent.

No leaking
