FloPlast Solvent Soil Short Boss Pipe – SS583 110mm

Bathrooms with several wastes suit the FloPlast Solvent Soil Short Boss Pipe SS583, a short piece of 110mm soil pipe with bosses moulded on, so wastes from a basin, bath or shower can join a Solvent Weld stack.

Why fit the FloPlast Solvent Soil Short Boss Pipe SS583

When a bathroom has two or three wastes coming to the stack, a boss pipe is tidier than a row of strap bosses. It goes in line with the stack and gives connection points at the height you choose.

Pencil in each waste height first, leaving room for a fall. Line the bosses up with those marks and swing them round to face each waste before the cement grabs.

Wastes connect through boss adaptors. Open any blanked boss with a clean hole of the size the instructions give.

Keep basin runs short so they do not pull water out of the trap. Clip the stack close to the boss pipe so the wastes do not drag it out of line.

Common Questions

How do I fit a soil pipe boss pipe? The SS583 goes into a 110mm solvent soil stack in line, the same as any other length of pipe. Work out your waste heights and turn the bosses to face them before you cement it, because it won’t move once it sets.

Which boss adaptor do I need for my waste? Go by the waste size: SS20 for 32mm, SS21 for 40mm or SS22 for 50mm in FloPlast’s solvent soil range.

How do I open the blanked-off bosses? Cut it out with a 54mm hole saw, then clean up the edge so the adaptor sits snug.

Why use a boss pipe instead of separate strap bosses? It gives you several waste connections at one height in a single neat fitting, which suits a bathroom with a basin, bath and shower all close together.

Can the SS583 go on an outside soil stack? Yes. It’s PVC-U for above-ground soil and vent pipework, so it’s fine inside or out.

Who would fix a soil pipe? A plumber is the usual person to call for a leaking or damaged soil stack. A confident DIYer can fit a part like this on a simple job, as long as each waste keeps a proper fall.
