Interesting. My Valterra was bought in 2009, no issues with it. Maybe a change in OEM lowered the quality.
Agree with buying Watts, the last one I bought for our S&B with silty water lasted at least ten years, that was even after a tenant removed the filter that protected it. When we didn't have tenants the first one lasted 25 because of proper filter changes.
