FloPlast Overflow 135 Deg Bend – OS12 21.5mm

The FloPlast Overflow 135 Deg Bend OS12 is a Solvent Weld bend for 21.5mm overflow pipe, the thin pipe that runs from a WC cistern or cold water tank out through the wall. FloPlast list OS12 as their 135 degree bend, which turns the pipe through 45 degrees.

Using the FloPlast Overflow 135 Deg Bend OS12

Overflow pipe needs to fall all the way outside and finish somewhere a drip will be noticed. A bend is handy for easing round joists, dropping through a ceiling void or kicking the pipe out through the wall.

Clean both faces, cement them, push fully home and give a slight twist. Keep a steady fall throughout, with no dips where water can lie.

Clip near the bend so the pipe does not pull on the joint. If you need a right angle turn, use the FloPlast 90 degree bend OS11 instead. Bring the job details to the counter if unsure.
