Can I bend this plug 90 degrees to get it into the drain line?** A: This is a tough call, simply because there's not enough details to go off.. however, depending on how deep the clean out sits below the surface of the soil, then I would not risk trying it. If the clean out opening is above ground and fairly easy to get to, that would make it a bit easier to bend the TP34 by pushing the center of the test plug rubber to create a bend. If the clean out is below the ground, I would not risk or take that chance of getting the test plug stuck. However, should you find away to slip the test plug into the clean out tee easy enough, then be sure to have liquid Dawn soap to allow the TP34 to be easily removed and slip back up and around the tight corner. If you are working with 3" sewer, then I would not attempt inert the test plug at all. 4" possibly! You should be able to see for yourself if the angle is to difficult to get around. Keep in mind that the TP34 waffle body is a very solid piece of rubber. Please contact us directly if you have further questions or doubts. **Q: my pipe is 4.25 inch (110mm), it works for me?** A: Are you measuring Inside diameter or outside diameter? It is designed for up to 4" inside diameter. Will it go another 1/4" if your inside diameter is 4.25", likely though I have only used on 4" id. **Q: I need to plug a 4” drain pipe for about 4 months. Will this test plug hold sufficient pressure?** A: I don't believe this plug is designed to last 4 months. The air pressure would likely leak out after a week or 2. As a plumbing contractor I've used many different types of test plugs and these are the best. For a long term plug, I would recommend some type of threaded cap or even a glue-on cap. **Q: Two toilets, common sewer connection clogged. Can I use this to plug one toilet so I can use a plunger on the other?** A: As long as you have a air pump or tire pump or something to inflate it ## Frequently Bought Together - Safe-T-Seal TP34 Waffle Body Pneumatic Hydraulic Test Plug Inflatable with Air or Water, 3 to 4 Inch - VIAIR 6 ft.
