PolyPlumb Branch and One End Reduced Tee 15mm to 28mm

The Polyplumb Branch and One End Reduced Tee has one large socket and two smaller ones. Pipe comes in at the big end, then both the branch and the far end of the run leave at the reduced size.

Why use a Polyplumb Branch and One End Reduced Tee

Picture a 22mm feed reaching a bathroom, where it splits to a basin and a toilet, both on 15mm. One 22x15x15mm tee does it, so you do not need a reducer on top of a tee. The 15x10x10mm size does the same on microbore heating, and 28x22x22mm suits a bigger main splitting into two 22mm legs.

• Sizes: 15x10x10mm, 22x15x15mm and 28x22x22mm
• One full size socket, two reduced sockets
• Polyplumb Push Fit joints
• Stiffeners needed in plastic pipe

Read the sizes off the fitting before you cut, because it is easy to turn it the wrong way round. Push each pipe in to its depth mark and pull back to check the grip. Clip the pipe close to the tee so the joints are not carrying weight. See the whole range in Polyplumb Fittings.

Common Questions

When would I use a branch and one end reduced tee?

At the end of a run, where a bigger pipe splits into two smaller ones, such as 22mm feeding a basin and a WC on 15mm.

Which end of the 22x15x15mm takes the 22mm pipe?

The first figure is the single large socket. Check the markings on the body before cutting.

Does it save fittings?

Yes, one tee replaces an equal tee and a reducer, so there is one less joint.
