Bathtub drains slow or not at all
My bathtub has been slow, very slow, on and off for years. Sometimes drain cleaner helps but most times it doesn't. We actually keep a plunger in the bathroom and my daughter now showers on a step stool! After furiously plunging for hours today I finally searched for the source. I found a drum trap which I was able to open with a hammer and screwdriver. I snaked the pipe as far as I could and found nothing noticeable. However, the drain was almost stopped but when I opened the drum it flowed down. If it's a vent problem then why is it only sometimes? I don't know what to do. It's beyond slow now.
