|In response to Re: 2" CheckMate Check Valve|
: : I am with a Forensic Engineering Firm. We are investigating a failed check valve. The one in

BUT once someone is asking for a sample check valve it seems to me that there are fishing for a possibility product liability lawsuit.
Before I would even get involved I would ask who the installer was how much "formal" training they had and if anyone bothered to look at the pump curves, Total Discharge Head (TDH)
Before I looked at the CV I would ask was this "pump" a centrifugal, rotary or reciprocating?
If this was a centrifugal "pump" was it horizontal or vertical
If it's a Rotary "pump" is it a vane, gear, piston, lobe progressing cavity, peristaltic or screw type?
Before I take on a case (lawsuit) I like to know before hand I am going to win by knowing all the facts not just one aspect like a check valve.
One has to take into consideration the job conditions and age of the installation.
Many times it is is human error not so much the product.
Price dictates some jobs not quality like the installers of AAV and wet venting.
I cant wait to jump on a law suit where an AAV was used and someone ends up with breathing problems.
Installers of the materials not suited for the actual job are the guilty ones and thus they should be hung out to dry not the maufacturer.
Like the guy who puts a snow plow on a motorcycle.
Should the snow plow or motor cycle maker be responsible?
Same with a "Check valve"
