Spears P418-338 – Frequently Asked Questions

1) What size Spears PVC DWV sanitary tees with side inlets are available, and which part numbers are they?
Two are offered: a 3 x 3 inch, part number P418-338, and a 4 x 4 inch, part number P417-420. Both are reducing side inlet sanitary tees, so the inlet openings step down from the run, for example a 3" x 3" x 3" x 2" x 2" configuration where the two side inlets take 2 inch branches. Order by the Spears part number, not by the run size alone, since a plain sanitary tee in the same run size has no side inlets at all.
2) Can I pick up two branch lines, like a back-to-back bath group, with one sanitary tee?
That is what the left and right side inlet version is for. The tee has an inlet on each side of the body in addition to the main branch, so two fixture branches can tie into the same stack point without stacking a second fitting or adding a length of pipe between them. It saves vertical space in a tight wall or joist bay where there isn't room for two separate tees.
3) Is a side inlet sanitary tee the right fitting for a vent, or do I need something else?
A sanitary tee is a drainage fitting, so its branch is swept to turn flow down into the stack. That makes it correct for a horizontal fixture branch entering a vertical stack, and correct where the upper run continues as the vent through the same stack. What it is not is a fitting for horizontal-to-horizontal drainage, a sanitary tee laid on its back traps solids. Use a wye and eighth bend for that direction.
4) What pipe does a Spears PVC DWV side inlet sanitary tee glue to?
PVC. The fitting is molded PVC, so it solvent welds to PVC DWV pipe of the matching trade size with PVC cement and primer. It won't bond to ABS, CPVC or PEX, so on a job where the existing stack is ABS you need a transition coupling rather than cement.
5) How many Spears side inlet sanitary tees come in a pack?
Five per pack. Worth knowing if you only need one for a single repair, and worth planning around on a multi-unit job where you are roughing in several identical bath groups, since the count lines up with stocking a few stacks at once.
6) Does PVC DWV hold up in a commercial building, or is it only for houses?
Spears PVC DWV fittings are used in both residential and commercial drainage. PVC is corrosion resistant, which is why it holds up in waste lines where cast iron would eventually scale and rust, and it is standard in multi-family and light commercial DWV. What decides it is usually the local code and whether the building requires cast iron for sound or fire-stopping reasons, not the fitting itself.
