Home Remodeling Doesn't Have to Be Stressful

My husband and I wanted to add an addition to our home for years before we finally decided to act on the idea. However, we then realized that we desperately needed to update our kitchen, as well. Before we started the remodeling process, we prepared for what we expected: stress. We made sure we cleared our calendars and didn't have any other major commitments during the remodeling process. However, once we began planning the renovations, we quickly learned that we were actually having a lot of fun! The renovation process also went very smoothly and, now that the process is over, we both joke around that it feels "too quiet" in hear without the company of the contractors. I enjoyed t all so much I decided to start a blog to share my remodeling tips to help others who will soon be taking the plunge!

How To Replace A Ballcock Fill Valve

Lee Hunt

If you have an older toilet filling slowly, the ballcock fill valve likely needs replacing. The ballcock valve is connected to the water supply line on the bottom of the toilet by a large nut. When you flush, a lever closes the valve as water levels increase. However, you may have trouble adjusting an older valve with corroded hardware. Here are some tips on replacing a ballcock fill valve.

Shut Off Water and Drain the Tank

Find the shutoff valve—commonly located near the toilet—and turn it clockwise. If there isn't a toilet shut off valve, you will have to shut off the main water supply. Flush the toilet to clear the tank and sponge access water. Since water could still drip from the supply line, set a container below the nut or lay old towels underneath it.  

Remove the Valve

Remove the toilet tank lid and set in a safe place on a pallet or old sheets. Examine the rubber washers inside the tank for cracks and replaced damaged ones along with the valve. Before you remove the ballcock assembly, lubricate the nut with penetrating oil and let it set overnight.

Disconnect the water supply line by unscrewing the nut. If the nut is plastic, you should be able to unscrew it by hand. Otherwise, remove it with adjustable pliers and push the hose away from the ballcock assembly.

Remove the nut connecting the valve to the tank which is over the one you just removed. Again, unscrew metal nuts with adjustable pliers. If penetrating oil doesn't loosen the nut, take a hacksaw blade and cut the valve shank near the china.

Press down on the ballcock so you have room to work. Disconnect the hose from the outlet on top of the valve and lift it from the overflow tube after removing the ballcock nut. Pull the balcllcock assembly straight out of the tank. 

Install the New Ballcock

Use the old ballcock assembly as a guide for finding a replacement. You could opt to replace the ballcock assembly with the new float cup devices which doesn't have a float arm or float ball.

However, metal or brass assemblies will last longer. Line the new fill valve assembly with the hole and tighten the nut and bolt. Reattach all other toilet components, turn on the water, and test the fill valve.

Replacing a ballcock fill valve should be easy. If your repairs don't stop the problem, you could have a hidden leak elsewhere which requires the services of a plumber (like those at DiRosato Plumbing and Heating).
