Frequently Asked Questions (FAQ)

What is the boss inlet used for on a 90° pan connector?

The boss inlet acts as an auxiliary connection port. It allows you to feed small-bore waste pipework (such as 32mm or 40mm lines from a bathroom sink, shower, or condensate drain) directly into the main 110mm toilet waste line without cutting additional branches into your main stack.

Do I need to use solvent cement or sealant on the pan seal?

No, additional sealant or solvent cement is not required on the rubber fins or the pan spigot end. The multi-finned rubber seal creates an airtight and watertight push-fit friction joint. Using solvent cement on rubber seals can actually damage the material and cause premature leaks.

The 90° Bent Pan Connector with Boss Inlet (B5155) is a highly versatile plumbing solution designed for tight, space-saving toilet installations. Whether you are fitting a close-coupled, back-to-wall, or traditional WC suite, this 90-degree elbow joint routes toilet waste smoothly into the soil stack when the outlet pipe exits in a different direction.

This model includes an integrated boss inlet, allowing you to route secondary waste lines—such as a bathroom basin drain or boiler condensate discharge—directly into the toilet soil pipe. This eliminates the need for extra pipe fittings or complex soil stack modifications, saving significant installation time for trade professionals and DIYers alike.

Built from tough, chemical-resistant polypropylene with flexible elastomeric fin seals, the B5155 guarantees a durable, leak-free connection that copes easily with thermal expansion and normal building movement.
