Toilet bowl slowly fills constantly

Hello,

I am trying to figure out what valve to replace for a toilet leak for a Mansfield 160. The toilet bowl slowly, but constantly refills water. Once the fill tank goes low enough, the tank then refills. Although the toilet bowl is constantly slowly filling, it does not overflow.

It seems that it could be the tank to bowl seal (which comes with 3 bolts), but I have never replaced one. I see there is also a flush valve seal and a fill valve (ballcock) repair kit.

Any advice which one sounds like the problem would be greatly appreciated. Thanks for your advice!

flush valve seal
I would say that is what you need. usually leaks through the flapper cause the symptoms you describe.

Put some food coloring in the tank, and if you see the food coloring in the bowl then the flapper is most likely the cause.

Is this the Mansfield with the tower flush valve? And with the plastic handle that goes through a loop in the tower?

Sounds like just the flapper valve; I would start with that. Cheap and easy.

Pretty good video here:

Great minds think alike (and sometimes type at the same time).

Thanks for the advice. Yes, exactly, it is the tower with the plastic arm that goes through the loop. The replacement parts are pictured in the site below.

Would I need a whole new tower or just the valve?

The Mansfield uses a rubber gasket on the bottom...see the red thing in the pics?

Bout a $2 item IIRC. Get 2 just in case....I've had some that had a crease or bend and would never seal. Try to get one thats hanging or laying flat...not crammed in a too small bin.

Seems like there might be 2 sizes....but not sure. Best to take it off and take it with you.

Thanks for the advice! I was hoping it was the red flush valve seal as it is the cheapest seal ($1.78 at Home Depot) and seems like the easiest one to install (plus there is a video for my exact tower). I will report back soon.
