PVC BOREHOLE PIPES
Dayliff PVC Borehole pipes are specially designed for all borehole installations being exceptionally strong and having an extremely secure jointing arrangement. Their many benefits include:-
- Made from strong non corroding uPVC for long life.
- Deep square thread spigot ends with rubber joint for easy coupling and an assured seal.
- Smooth surface finish reduces hydraulic friction and increases pump efficiency.
- Very light and easy to handle.
- Suitable for water temperatures up to 70°C.
- Economical to buy and install
Dayliff PVC Borehole pipes are available in 3m lengths in medium, standard, heavy and super heavy duty specification for different pressure ratings in sizes from 1¼” and 3” and all installations include steel pump and well head connectors. For extra deep installations a piping/connector bracing kit is available for additional security. They offer very considerable advantages over traditional steel pipe alternatives and are the ideal solution for all borehole pump installations.
