    Running pool pump without a main drain

    Hello pool community, very excited to be here. We just bought a house from bank and recently found out that the pool has a leak in the main drain. We are trying to run pump without it and it's not priming. The pool tech came and blocked the main drain from the bottom with a plug so that water does leak. We have just installed a Pentair Ineliflow pump with self priming capacity. Very new to pool so I will appreciate any help. In the mean time I will start reading all the great posts to understand the pool functioning. Thank you for your help.

    If you had a pool tech there I'm sure he made sure that your water level was high enough (half way up the skimmer box frame)....right???

    Check out the link in my signature: Fake Main Drain.

    Short answer: Yes, you can run a fully functioning pool just fine on Skimmer suction only.

    However, you may want some kind of automated pool cleaner to pick up debris that the MD might normally get.

    Put a hose in the pump basket and run it until water overflows the basket, put the lid on and start the pump. Give it at least a minute to prime. Look at your watch, a minute is eternity when waiting.
