OATEY 271838 – Frequently Asked Questions
1) Will the Cherne Clean-Seal 2 plug seal in a cast iron cleanout tee?
Yes. The Clean-Seal 2 uses a multi-lobe gasket that seals all tees, cast iron included, where a single-lobe gasket can struggle on the rougher inside wall of a cast iron fitting. It hand-tightens in place, so no wrench or tools are needed to set it.
2) How high a water column can a 3 inch Clean-Seal 2 plug hold back?
The plug is rated for 13 PSI of back pressure, which Cherne states as 30 feet of head. That covers a typical three story DWV stack test. Inflation pressure is 35 PSI, so set it there and do not over-inflate trying to gain holding capacity.
3) Can I test a DWV system with air instead of water using the Clean-Seal 2?
Yes, either one. The Clean-Seal 2 keeps the features of the original Clean-Seal and adds the ability to test with air or water, so the same plug covers a jurisdiction that wants an air test and one that wants water.
4) Do I still have to fill a DWV system from the stack when using a Clean-Seal 2 plug?
No. You plug, fill and drain from the same cleanout tee, which is the point of the design. That removes the trip to the roof or the top of the stack to fill, and it replaces the multi-piece fill setups plumbers otherwise rig up.
5) Can I pull the fill hose off the test plug without losing the water in the system?
Yes. A check valve in the plug lets you take the hose off after filling, and it also stops DWV water from back-filling into the potable line you filled from. A rubber cap covers the hose connection when the plug is sitting idle, which keeps debris out of the fitting between jobs.
6) What is the difference between the Cherne Clean-Seal 2 and the original Clean-Seal plug?
Same reliable features on both, with the 2 adding air testing alongside water. If your inspector accepts a water test only, the original does the job; if you need to pressure the system with air, or you want one plug that handles either call, the Clean-Seal 2 is the one to carry.
7) How much does a 3 inch Cherne test plug weigh for a service truck kit?
About 0.85 pounds, so a set of them in several sizes adds almost nothing to the van. The body is yellow, which is what you want when a plug is sitting down in a cleanout and you are counting them back out at the end of the test.
