Hi all, I’ve a customer with a failed double check valve on a water softener, it’s 22mm compression but with a far larger bore than the usual DCV’s you see online. Anyone know if they are called something different or where I can get one? I’ve even been on the water softener website and they don’t seem to sell them. Ta.

Yep, I took it out to check it, definitely no CMI’s. But that is a useful thought as a replacement.

That’s what I normally do
Another option is a swing check valve have to be installed horizontally tho

It’s not, but that’s the first one I’ve seen rated as high flow. What’s the web address?
Dear Marc, how did you identify the failed double check valve on a water softener? The inlet to our Harvey's softener has been making a clunking noise intermittently for 5 days now. Could it be the same problem as yours? Thanks so much for reply Sara
My problem was flow rate. A clunking noise is usually water hammer and can have a number of sources (not necessarily in the area of the noise)
