Hey BoomerHarley,
Very sorry for the poor experience(s) you've had with our products. The manifolds are something that we're currently working with our supplier on getting fixed. Some of them have faulty check valves, some require extra teflon tape, and others have a relief spring that doesn't sit quite right. What I've done with mine (also a little leaky prior to fixing) was put it in a bucket of water with it turned up to 20psi. Was able to find the leaky thread, added more teflon, and that took care of the issue for me. This being said - we don't expect our customers to have to do this: We'll gladly replace the defective product for you and would even be happy to fill a bucket of water and test it prior to sending you home with what could be another defective product.
The bottles are strange, as I have a few cases that I've never had an issue with. I have heard of problems with them, but it's usually 1, maybe two of the 12 bottles have a leak. Never the entire case. This being said, it sounds like you do have a faulty case (or possible more than one case) that we'd be happy to return for you. If you'd prefer to swap them out for other bottles, or would just like a refund, please don't hesitate to bring them back and we'll look up your account and refund you for 100% of the cost of the bottles. Manifold too if you'd like to return it rather than exchange it.
I again am very sorry for the issues you've had with a couple of our products, but would like you to know that we pride ourselves with quality customer service. Even if you'd still prefer to shop elsewhere, I'd encourage you to return those products so that we can make this right for you. I know there's no way to replace the flat beer that you've spent hours brewing, and months upon months to condition, but if you'd like I would even be happy to help you get the proper ingredients to brew that batch again. I don't work in the Concord Showroom, but am located in the Concord location and am more than personally assist you with anything you need.
Please feel free to PM me if you'd like, and I'll try to help however possible. Thank you for the feedback, and again, very sorry for these inconveniences.
Sincerely,
Matt Monroe
