OATEY 88043 – Frequently Asked Questions
1) Does the Oatey 88043 roof drain take 3 inch or 4 inch pipe?
The Oatey 88043 roof drain body accepts either 3 inch or 4 inch ABS drain pipe, so one drain covers both common leader sizes. The connection is a solvent-weld ABS socket, which means you glue it to ABS pipe rather than threading or clamping it.
2) Is the dome on the Oatey 88043 plastic or metal?
Metal. The 88043 pairs an ABS drain body with a cast iron dome strainer, which is the part that takes foot traffic and impact on the roof. Cast iron holds up better than a plastic dome on a roof that gets walked for HVAC service.
3) What does the dam collar on an Oatey roof drain do, and is it included?
The dam collar ships with the 88043. It is a ring that sits around the drain to hold back a controlled depth of water, which is how a controlled-flow or secondary roof drain is set up so the roof sheds at a metered rate instead of all at once. If the design does not call for ponding, the collar can be left off and the dome installed directly.
4) Should I use an ABS roof drain or a cast iron one on a commercial reroof?
An ABS-bodied drain like the Oatey 88043 is the lighter, faster option where the leader piping is already ABS plastic: you solvent-weld it instead of caulking a lead-and-oakum joint, and the whole assembly is about 10.55 lbs. Go to a full cast iron drain where the spec calls for metallic DWV throughout, or where the drain sits in a traffic-rated area. The 88043 splits the difference by keeping the exposed dome and grate in cast iron while the buried body stays plastic.
5) What part number do I order for the Oatey ABS roof drain with the cast iron dome?
Order Oatey 88043. That single part number covers the ABS drain body sized for 3 inch or 4 inch pipe, the cast iron dome strainer, and the dam collar, so there is no separate dome or collar to add to the order.
