Review on Kerick Valve PF06 Polyethylene Diameter by Ray Mcknight

My old toilet was in need of repair. The existing tank ball was quite small. When the ball lifted the locking lever, the lever often did not close fully, possibly due to corrosion. I would have to remove the lid from the toilet bowl and lift the lever to get the water to stop internal leakage and water wastage. So I decided to buy this 6 inch ball which solved the problem. The existing reservoir sphere was only about 4 inches in diameter. The 6 inch ball has much more buoyancy and raises the locking arm with more force. So now my dresser no longer has an internal leak. The water is completely turned off. Please note that this 6" sphere is unlikely to fit in a modern toilet bowl water tank (too large). But I have an older dresser with a larger tank, and this 6" bowl barely fits in it. I want someone to make a 5 1/2" ball. They sell a solid square/rectangular ball that will probably fit and add extra buoyancy. That 6" bowl also fills the inside of the tank and lets me use less water when I flush the toilet; it also prevents all the water from escaping the flapper hole at the bottom of the tank, meaning there is always a little pressure on the flapper to prevent leakage.
