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.
