FloPlast Ring Seal Solvent Boss Adapter – SP22 50mm

For the larger waste size, the FloPlast Ring Seal Solvent Boss Adapter SP22 brings a 50mm waste into a boss on a soil stack fitting. The waste side is a solvent socket for ABS pipe.

Jobs for the FloPlast Ring Seal Solvent Boss Adapter SP22

Bigger 50mm pipes are found on laundry rooms, catering sinks and shared appliance runs. Where that pipe meets the stack, this adaptor makes the joint in a boss pipe, strap boss or boss branch.

Fit the adaptor into the boss as the instructions say, and keep it square. Once it has set, cement the 50mm waste into it.

A full 50mm waste is heavy, so clip the pipe close to the boss and do not let it hang off the adaptor.

Keep the run falling all the way into the stack, with an access point upstream in case of grease blockages.

Common Questions

What is a soil pipe adapter? It’s a fitting that lets a smaller waste pipe join a soil stack. The SP22 glues into a boss on a 110mm soil pipe or fitting and gives you a 50mm solvent socket for the waste.

How do I fit a soil pipe boss adaptor? Dry-fit the waste run first and check it falls back to the stack. Then cement the adaptor squarely into the boss, cement the waste pipe in, and leave it a minute or two before moving it.

Can I remove a solvent weld boss adaptor later? Not really. Once the cement has set the joint is permanent, so if it’s in the wrong place you’ll normally have to cut out and replace that section.

What kind of waste pipe does the SP22 take? It’s for 50mm solvent weld waste, such as FloPlast’s 50mm ABS solvent pipe, typically used on larger kitchen and utility wastes.

Is there a push-fit alternative? Yes, FloPlast’s SP12 rubber boss adaptor fits the same bosses and can be taken apart if you need to.

Do I need to clip the waste pipe near the stack? Yes. A 50mm pipe full of water is heavy, so a clip close to the stack stops it pulling on the joint.
