Frequently Asked Questions

What does a reducing bush do?

A reducing bush allows you to connect a larger fitting to a smaller pipe. This 100mm x 80mm bush steps down from a 100mm (4") socket to accept an 80mm (3") pipe, enabling you to transition between pipe sizes in your pool or spa plumbing system.

How is the FRR108 reducing bush installed?

This reducing bush uses a solvent weld (glue) connection. Apply PVC solvent cement to the outside of the bush and the inside of the fitting socket, insert the bush, and allow to cure before use. No threading or mechanical fasteners are required.

What fittings is this reducing bush compatible with?

The FRR108 glues directly into standard 100mm PVC fittings including elbows, tee pieces, and couplings commonly used in pool and spa plumbing.

Can this be used for pool and spa plumbing?

Yes. This PVC reducing bush is suitable for pool and spa plumbing applications where a reduction from 100mm to 80mm pipe is required.
