Customer Reviews for Oatey Gripper 4 in. Plastic Mechanical Test Plug

Just as described. Fit perfect for my needs

We are waiting for a new septic system to be installed. In the mean time, every time we get more than 1” of rain in a 24 hr period, I have sewage flooding the lower level of my house. Someone suggested these. I did have to remove the toilet from the floor, and the sink vanity, but the floor was ruined and I needed to gut the bathroom anyway. So I put these in all the drains on that level, 6 in total. We had over 2” of rain in about 12 hours with no overflow. Hallelujah!

A technician recommended the product. You have the two sizes we needed.

Works exceptionally well. Plenty of grip and resisted water intrusion from both directions

Poor quality merchandise

So far so good. Need to cap a rusted drain before it got repaired and this plug did the trick.

I installed this plug on my basement floor and I have no more smell which was strong.

Our village sent out a notice of power back washing the sewer lines. I wanted this plug as a "Just in Case" measure. It worked like a champ. I have heard some of my neighbors had problems but because the village sent out the message and a little pro-action, my basement was dry.

Worked perfectly to plug up a 4” pipe left uncapped by the builder.

It’s certainly easy to find, in our front yard. I don’t think, if these even we re made, when we bought this house 30 years ago, that I would have been able to find one. Our clean out doesn’t have threads on it, so this works great!

Perfect fit to cover the outside drain

[This review was collected as part of a promotion.] If you are going to be doing any plumbing or remodeling this is a must. I pulled my toilet to put down a new ceramic floor and this plug kept all the mast sewer gasses from filling up the house!
