Overview

The Holman Storm PVC Elbow F&F 90mm 22.5 degree is a low angle female-female elbow for 90mm stormwater pipe. It gives a gradual change of direction in a pipe run, sitting between the 15 degree and 45 degree bends. It is the fitting to use where a pipe needs to step across a slab or align with an outlet without a sharp turn.

It is made from quality recycled PVC and used for stormwater and rainwater drainage in residential and commercial buildings. Both ends are female sockets, and the fitting is solvent welded into place. It complies with AS/NZS 1254 for stormwater fittings.

What You Need to Complete the Job

Dry-fit the elbow to confirm the angle lines up, then solvent weld the joints. Use it with the 90mm stormwater pipe and cement with Bostik Pipe Cement Type N. Combine it with the other elbows in the range to build a full run around corners and steps. More fittings are in the PVC Fittings range.

Frequently Asked Questions

How does the 22.5 degree elbow compare to the other angles?

It sits between the 15 and 45 degree bends in the Storm PVC range. The lower the angle, the gentler the change of direction and the less flow restriction. Use 22.5 where the pipe needs a moderate step, and combine angles to build the exact change you need.

Can I combine two 22.5 degree elbows to make 45 degrees?

Yes. Two 22.5 degree elbows give a total change of 45 degrees, and you can mix 15, 22.5 and 45 degree elbows to match almost any angle in a pipe run. Dry-fit the combination first to confirm it lines up before cementing.

Is this elbow suitable for a tank overflow line?

Yes. A low angle elbow is a good choice for a tank overflow or a long pipe run where you want to keep flow moving and avoid sharp bends. It is made for stormwater and rainwater drainage and complies with AS/NZS 1254.

What pipe does this fit?

It fits 90mm stormwater pipe. Both ends are female sockets that accept plain 90mm pipe ends, and the joint is made with solvent cement. It is part of the Holman Storm PVC 90mm fitting range.
