Answer: 
This ballcock is 12" tall, not 10.75. If your tank isn't 12" or higher on the inside, this ballcock will not fit. I ordered this item, and it is a standard 12" ballcock. I had to return it.

The original has doubled my water bill since it keeps 'trying to fill' and runs into bowl.
Plastic at top cracked and can't be adjusted.

Answer: 
The height is 12 inches. Measure your tank, if it is a one piece toilet you need some thing closer to 8. Any brand will do so long as it fits and does not interfere with some thing else. The Danco (8 inch model) will probably work but you need to know the height of the tank. Fluid Master may be able to give you a recommended model over the phone or by e mail

Answer: 
Thank you for your inquiry. This will likely be too tall to fit your one piece toilet. Our replacement for the Coast 1B-1X is Danco part #41036.

I can't tell who manufactured my ballcock, but it is a Mark IV. And it's approx. 12" high. Will this item be a suitable replacement?

Slow filling toilet tank, and everything in it is 8 years old, so I figured it's time to replace the toilet valve.
