Toilet only draining sometimes
There was a clog in my toilet. I plunged it and the toilet drained. Since then, the toilet will SOMETIMES drain (about 70% of the time). Other times, the water swirls and partially drains, but, not all the way. What's in it doesn't seem to make a difference. For example, I've flushed it four times in a row (with nothing except water in it) and it's fine, but, then the fifth time (with only water in it), it won't suck all the water down. It's an older house (77 years), and I just moved in two months ago, so, I'm really not sure if this is even how the toilet normally works or not. I am not very handy, but, I'm willing to get dirty, so, any ideas?
