A necessary part for flushing and refilling, ballcocks and fill valves make sure your toilet fills up after each flush and ensure flow is turned off when the cistern is full. Our wide range of fill valves includes more traditional ballcocks as well as modern valves with features like quiet operation and adjustable installation.
What is a ballcock?
A ballcock is a type of fill valve that uses a float on a metal arm to make sure a toilet doesn't overflow when refilling. The floating ball is attached by an arm to the valve and turns it off when it floats to a certain height.
What's the difference between a ballcock and a fill valve?
A ballcock is simply a fill valve with the float and arm attached. Some modern fill valves do not use a ballcock and are more efficient, and smaller.
Do all fill valves fit all toilets?
Fill valves have a universal size that fits all modern toilets, and fill valves with adjustable heights can fit toilet cisterns of different sizes.
What do I need to replace a fill valve?
Fill valves can be removed, screwed in, and adjusted by hand and don't require any tools for installation. You will know it’s time to replace a fill valve if your toilet keeps refilling and overflowing or if it fails to refill after being flushed.
