FloPlast Offset 135° Bend Socket/Spigot – SS435 110mm

When a soil stack runs up an outside wall, it usually has to jog out to clear the soffit and gutter, and the FloPlast Offset 135° Bend Socket/Spigot SS435 handles that step. This 110mm Solvent Weld offset has a socket at the top and a plain spigot below.

Using the FloPlast Offset 135° Bend Socket/Spigot SS435

Fitted as part of a swan neck round the eaves, the offset steps the stack out and lets it carry on above the roofline. Its spigot goes directly into the next socket, which keeps the offset compact without an extra length of pipe.

Mark the alignment before gluing, because solvent soil joints set quickly and there is no adjusting once they grab. Clean both surfaces, cement them with a good coat, push home and hold. Wipe away the surplus.

On a vertical stack, keep the socket facing up so water passes over the joint rather than into it. Clip above and below the offset to carry the weight of the stack.

Common Questions

How does the SS435 help a stack clear the eaves?

Two of these offsets with a short piece of pipe between them make a swan neck. That steps the stack out past the soffit and gutter so it can carry on up.

Should the SS435 socket face up or down on a stack?

Face the socket upwards. Water running down the inside then passes over the joint instead of into it.

Is it fine to leave the olive grey finish unpainted outside?

Yes. FloPlast say PVC-U soil pipe can be used outside with no paint needed, so the colour is purely about matching the house.
