Minor Problems With Holes
There are two minor problems with this cover.

1) There are 3 holes, but it only comes with one hole "cover" for the electrical. If you need to cover another hole, you have to buy a cover somewhere.

2) The electrical hole allows the power cable from the pump to go out nicely. But my pump had 2 power cables, so I had to adapt it a bit.

So it depends on your application.

George,
The reason why this cover has 3 holes is because it is a sewage basin. The hole that you covered up is the vent, which allows sewer gas escape to the outside of the building. You may want to review your installation with a licensed plumber.

Less Rigid Than Expected.
I would buy the steel one if I had it to do over again. It's not flimsy, but flexes more than I expected when walked on. I would have preferred a pipe exit on side of basin so piping didn't have to be removed just to get inside.
