OATEY 285072 – Frequently Asked Questions
1) Will a 6 in. mandrel fin gauge tip or ride up inside the pipe during a pull?
No. On the 4 in. through 15 in. gauges the fins carry a skid size equal to the nominal pipe size, which keeps the gauge riding true in the line rather than tipping, and lets it meet regional code requirements. The open body also lets gravel and debris pass through instead of packing up in front of the gauge and giving a false stop.
2) What is a mandrel fin set used for on a new sewer line?
It is the gauge end of a deflection (mandrel) test. Pulled through a newly installed flexible sewer main, the fin set confirms the pipe has not deflected beyond the allowed percentage. The 285072 is cut to the 5 percent limit for 6 in. SDR 35 pipe, which is the common acceptance figure inspectors call for on gravity sewer. The nine-fin design is what gives the gauge its measurement accuracy, and it is field-verifiable without a proving ring.
3) Will the Cherne 6 in. mandrel gauge fit down a standard manhole?
Yes. All sizes in the Cherne fin set line, including the 6 in., pass through a standard 24 in. manhole, so the gauge can be lowered and retrieved without opening up the line. At 0.15 as listed for product weight it is a one-hand lift for a single crew member.
4) Does the Cherne 285072 fin set need tools or a separate mandrel body to assemble?
The fin set assembles without tools. It is the fin (gauge) component ordered by size and deflection percentage, so you match it to the mandrel assembly and pull cable you already run. The 285072 covers 6 in. SDR 35 at 5 percent.
5) Will a mandrel fin set corrode if it sits in a wet sewer line between tests?
The Cherne fin set is built lightweight and corrosion resistant, so repeated pulls through wet gravity sewer and storage between jobs will not rust the gauge out. That matters for a contractor or municipal crew testing line after line across a season.
