Installation Instructions

Disclaimer:

The following advice is given for reference only, and is based on the best practices and suggestions given by professional plumbing contractors. This information is by no means comprehensive. American Valve bears no responsibility for the improper installation or misuse of its Plumbing Valves. Please see our warranty and terms for more information.

PEX Connections:

Follow the instructions given by the crimp ring and crimp tool manufacturer.

IPS Threaded Connections:

Always use thread tape or sealant. Hose threads do not require tape or sealant.

Compression Connections:

Tighten nuts by hand then 1/4 turn with an adjustable wrench. Restrain pipe on both sides. Do not over-tighten. Compression joints will fail if the pipe moves even a little bit after tightening. Do not reuse the same section of pipe for another compression nut. Test connection before concealing.

Solder Connections:

Do not disassemble the valve. Clean all the surfaces to be soldered with a fine sand cloth or steel wire brush to remove all traces of dirt and oil. Use a thin film of flux to cover the surfaces. Use flux sparingly, but be sure to cover the entire surface. Always use lead-free solder for plumbing parts.
Open the valve fully and carefully to apply only as much heat as is needed to melt the solder. If you are using MAPP gas then you should exercise additional caution as it will be hotter than propane.
It is a good idea to make sure the flame only contacts the ends of the valve and not the center section, where the soft Teflon seals could be damaged. Apply heat to the tubing first and transfer as much heat as possible to the valve through the tubing to avoid overheating the valve.
When the temperature of the parts is hot enough to melt the solder, remove the flame. Solder is then applied to the joint and will automatically fill the joint through capillary action. Use about a 1/2" length of solder for a 1/2" valve, 3/4" length of solder for a 3/4" valve, etc. Using too much solder will make a weak joint.

PVC & CPVC Valves:

Follow the instructions given by the solvent and primer manufacturer. Hand-tighten all threaded connections.
