FloPlast Overflow Tee – OS13 21.5mm

Saving a second hole through the wall, the FloPlast Overflow Tee OS13 lets two overflow pipes share one run out of the building. It is a 21.5mm Solvent Weld tee from FloPlast’s overflow range.

When to use the FloPlast Overflow Tee OS13

Where two overflow runs meet, the tee joins them so a single pipe carries on to the outside. It also gets used on condensate runs.

An overflow is a warning pipe as much as anything, so the household needs to be able to see it running. If two cisterns share one outlet, you still need to be able to tell which one is discharging, so check the water regulations before combining them.

Cement each joint and keep every leg falling towards the outlet. Clip the branches close to the tee so neither pipe can sag and hold water. A dripping overflow means a fill valve or float needs attention, so it is worth fixing the cause quickly rather than living with it.
