Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.

Frequently Asked Questions

Q. "Why does the expansion seal (plug) need to be at least 6 inches from the solder joint?"
A. The plug should be at least 6 inches from the solder joint in order to prevent it from melting.

Q. "My water is flowing more than a trickle. Will the Wassi water stopper halt the flowing water?"
A. It will for only a brief period of time. Pressure will build against the plug and eventually push it out with great force.

Q. "How can I reduce the chance of pressure buildup against the plug?"
A. If there is a faucet, hose bibb, or any other way to release water/pressure between the seeping shut off valve and the plug, you can open it to keep pressure from building. If not, extreme caution should be taken.

Q. "How long are the cables?"
A. The overall length is 20 inches, however the cable should only extend into the pipe approximately 12" to protect the plastic handle from coming into contact with the torch flame.

Q. "Why do you caution against pressure buildup if water is just trickling out of the pipe?"
A. When the trickle is flowing free, there is no pressure. When it is plugged off, pressure will increase until it's equal to the supply pressure. The smaller the pipe, the faster the pressure will increase. Have everything ready to solder before you close the plug.
