Changed the skimmer years ago and it did not allow adjustment of suction between the top and bottom of the pool, it acted more like an equalizer if anything... Finally broke down and replumbed everything with valves that allow water to be drawn from top, bottom or both, and I usually leave it set for "both".... Immediately started to notice less dirt on the bottom and quicker recovery from an upset where the water has gone cloudy for whatever reason.... A main drain is a MUST HAVE.

What I used to do with my cette main drain is brush all the settled sediment at the bottom of the pool towards the center and leave it on full main drain for a few hours then switch the valve back to skimmer. Hardly ever had to vacuum despite being close to quite a few trees.

Hi Chad, thanks for putting up all these videos, but I didn't see any mention of the safety regulations (Virginia Graham Baker) related to proper setup and configuration of main drains to limit entrapment dangers. I am not sure if the laws are federal or state. I have heard several different approaches but not sure what is considered minimally safe by law. Two main drains rather than one, so if one is obstructed the other acts as intake relieving suction. Anti-entrapment grates and electronic sensing and motor shutoff are also other features I have heard about.

It may sound like a simple solution, but if you are using the main drain for cleansing purposes, just turn it off when people are swimming. Duh.

Little more trouble to winterize a pool with a main drain also. Need to use a compressor to blow the water out of the line to create an air lock.

Non toxic antifreeze for pools. Fill the pipe till you see it rising out of the bottom drain.

1 have 2 main drains that T on a 18 ft above ground pool. But can't get it to start sucking again cause I pulled the plug on the bucket on the pump too early and the suction stopped. I tried putting water back in the line and even filling the hose up with water and air tight then seeing if it would siphon. Start!! But that didn't work I'm wondering if I have my 3way valve on wrong setting? And does water need to be put back in the basket on the pump too for that line? Hope I'm making sense. It's hard to explain in a text. PLEASE HELP ME. 🙏🏻 I USE THIS POOL FOR AQUATICA THERAPY FROM BRAIN SURGERY.

+Victor Garza the main drain will have to be positioned in the center of the pool and the distance to the pump will fall as it is. I prefer at least a 1 & a half horsepower pump.

So if I have a skimmer that is 40 gpm and a main drain that is 40 gpm, I should have a pump that does 80+ gpm if I want to run both at the same time?

There is a compressor fitting which attaches to where the main drain pipe comes above ground by your filter. These fittings are usually sold in kits. You pump air into the piping until you see bubbles coming from the main drain and that's practically all.
