Main Drains in Sport Pool

Hi, just a question about main drains.

Is there an issue having main drains in a vinyl liner sport pool where the center is only 5.5' deep. I am worried mostly that people will stand on them. PB thinks I should have them and I agree; but not sure if recommendations are different for shallower pools like this or if main drains are still fine.

Pools go without main drains all the time these days. That's one less cut in your liner. If you ever wanted to lower the water you could use a sump pump or on a more limit way your backwash/waste option if your filter has it.

I am a huge fan of main drains. I have lots of tree crud/dirt/sand that falls to the bottom and we winterize here and need to drain. In a sport pool however i dont like them and would consider them toe-smasher-3000's.

I have 2 main drains in a sport pool. The covers are pretty solid if you are thinking someone will break them. My depth is 6 ft from the top of the water so people shouldn't be standing on them. Where is the 5.5 ft measured from?
