Flexible hose made of polyvinyl chloride is used mainly in pool, spa and landscaping applications. It is not recommended for hot water or drinking water. Flexible PVC is generally more expensive than rigid PVC, but it is just as easy to work with and readily available. Much like cross-linked polyethylene hose, or PEX, flexible PVC hose can be maneuvered around many obstacles that would require drilling holes and using multiple connections with rigid hose. In most applications, the same fittings, primers and glues used for rigid PVC can be used with flexible PVC.
Things You’ll Need
• Plastic tubing cutter or utility knife
• Steel wool or fine sandpaper
• PVC slip connectors
• Pencil or felt tip pen
• Newspaper or rags
• PVC primer
• PVC cement
Cut the ends of the hose, making sure the cuts are square.
Make sure the hose ends are clean and smooth, with no large marks or defects. Clean the ends of the hose with steel wool or fine sandpaper, if necessary. Clean the interior of each PVC slip connector.
Dry-fit the plumbing assembly to make sure all the pieces go together properly. Mark the individual pieces of a complex assembly to help position them correctly when you glue them together.
Spread rags or newspaper beneath your work area. Make sure the area has good ventilation.
Apply PVC primer to the exterior ends of the hose and the interior of each slip connector using the dauber provided with the can.
Apply PVC cement to the primed areas of the hose and connectors. Assemble the hose and connectors quickly, turning each connection 1/4 of a turn as you insert the hose. Be sure to line up any orientation marks you made earlier. Hold the assembly firmly together and count slowly to 10.
Follow the glue manufacturer’s recommendations on the amount of time the assembly should cure before you can test it for leaks.
