Pasco 2912 Sump Pump Check Valve Silencer

The Pasco 2912 Sump Pump Check Valve Silencer is a rough-in plumbing accessory built for sump pump discharge lines, designed to help quiet the check valve action commonly heard as the classic "thump" or slam when a sump pump cycles off and the check valve closes against backflow. This accessory is available for check valve installations sized 1-1/2" through 2", giving plumbing contractors and installers a single go-to solution across the two most common sump pump discharge line sizes found on residential and light commercial jobs. Pasco packages this accessory for the trade, supplying it in cartons of 50 EA with a minimum order quantity of 1 EA, making it a practical stocking item for plumbing contractors, sump pump installers, and supply houses that need a reliable accessory on hand for service and new-installation calls. As with many plumbing components, this item carries a Prop 65 warning, so installers and retailers in California should be aware of applicable disclosure requirements when handling, stocking, or selling this product.

Pasco 29121 – Frequently Asked Questions

1) What size sump pump discharge lines does the Pasco 2912 check valve silencer fit?
Two sizes cover the 2912 silencer: 1-1/2 inch (part 29121) and 2 inch (part 29122). Those are the two discharge line sizes you run into on most residential and light commercial sump installs, so match the silencer to the nominal size of the check valve already in the line. There is no single unit that covers both, so order by size.
2) Will a silencer actually stop the thump when my sump pump shuts off?
That thump is the check valve slamming shut against backflow when the pump cycles off, and the Pasco 2912 is built specifically to quiet that action on a sump discharge line. It is an accessory for the check valve installation, not a replacement valve, so you still need a working check valve in the line.
3) Is the Pasco 2912 a check valve itself, or something you add to one?
It is an accessory that goes with a check valve installation on a sump pump discharge line, sized for 1-1/2 inch and 2 inch check valves. If your check valve is failing or leaking back, the silencer will not fix that; you need a new check valve and can add the silencer for noise.
4) Can I buy just one Pasco 2912 silencer for a service call, or do I have to take a full case?
Minimum order is 1 EA, so a single unit for one service call is fine. Pasco cartons them 50 EA for shops that want to stock them on the shelf or on the truck.
5) Which Pasco part number do I order for a 2 inch sump discharge?
For a 2 inch line the part is Pasco 29122. The 1-1/2 inch version is 29121. Both are the same silencer accessory, just sized to the check valve.
6) Does the Pasco 2912 carry a California Prop 65 warning?
Yes, the 2912 sump pump check valve silencer ships with a California Proposition 65 warning designation. Distributors and retailers selling into California should handle the disclosure accordingly.
7) Is the Pasco 2912 silencer worth stocking for a property management or multi-family maintenance program?
It is a reasonable stocking item if you maintain basement or crawlspace sump systems where tenants complain about the slam. Cartons run 50 EA, the two sizes (1-1/2 inch and 2 inch) cover most residential discharge lines, and you can order as little as 1 EA to try one before committing to a case.
