I have a shower that is draining very, very slow. I have tried using a plunger, but the water just goes up the drain of the garden tub next to the shower. I am unable to remove the drain cover in the shower. Could I run a snake through the overflow valve in the tub? (The water drains from the tub, to the shower, and then outside.)
My other idea was putting the shop-vac hose down the clean out towards the house, blocking off the tub drain/overflow, and using the plunger in the shower.
Any thought/suggestions would be greatly appreciated!
