They are expensive and in many cases an "overkill".

I'm with you brother, but the great nanny state of San Francisco requires them.

People say it cost a lot then one has to ask how much is the public safety worth?

 

[Robinasu]

Good point. Firdt, I would also ask how effective the units really are and is the total economic cost reasonable, or in the region of diminishing returns.

 

[hj]

There are MANY other options which are just as effective and less expensive. Where the ARE required it is because the OHJ decided on the "one size fits all" apprroach.

Based on the parts diagrams I like the Wilkins 975xl2. Any suggestions?

I have a Wilken backflow device, can't say specifically the model, but it is tested each spring and occasionally minor repairs like O rings are replaced, but nothing major as far as cost is concerned. I would venture to opine than any major manufacturer's device would be as reliable as then next. They are all man-made devices and subject to needing repairs. That's why annual certifications are required. Even a Rolls Royce has to be repaired sometimes. Get what you like based on whatever you think has the best parts diagram.

Point is, if your local codes require it, you have to comply, regardless of cost. I'm not saying that this is required by your code, be that is what you implied in your original post. Maybe further inquiry to your local authority to see if there are other options.
