Obstructed main drain

Postby cooperc2 » Tue 02 Apr, 2019 13:02

I have a 30" above ground pool with a main drain and skimmer. The skimmer is the only line with a shutoff valve. We had some problems with the liner and had to go ahead and uncover the pool before I was ready. After fixing the liner I decided I may as well leave it open and just do my best to keep it clean until the water warms up enough to get in. I usually vacuum my pool using the main drain due to the fact I can close the skimmer valve for better suction. But since it's still so cold and I needed to vacuum I used a reach pole to place a tennis ball over the center main drain , then hooked my vac to skimmer . It worked great and I was able to get pool vacuumed , I shut off pump and went around to remove tennis ball. The tennis ball somehow got sucked into the main drain pipe , I don't know how far , I just know I can no longer see it. Help please

You don't need a main drain so leave it blocked. Eventually the ball will rot and it will work again.
All dirt enters a pool from above so if the skimmer works properly you don't need a main drain.

I agree except it's just blocking it enough to cause air in the line , not enough to completely block it. I had planned on capping it this season anyway since I do not have a shut off for it . I really don't see it helps keep my pool any cleaner . It just winds up being a headache Everytime I get ready to vacuum.

I am not sure how blocking just enough to cause air in the line for a main drain that is under water? To me if you block the line and you are drawing in air you have a pipe leak on that line.
