New fill valves

I bought my house new. The builders were cheapskates - and that's putting it nice! The toilets they put in my bathrooms are the absolute bottom of the barrel. For the past few months two of the toilets have been continuous running water. But today that changed. I went to home depot and chatted with the plumbing expert. He told me all I needed was a new fill valve and assured me I could do it myself. Krista and I spent almost an hour figuring out the first one. After that, we had the other two in in less than 20 minutes! And now the water in the toilet tanks actually stops running when the tank is full!! I'm so handy!
