What is the difference between a bottom valve with and without overflow?

Typical foot valve without overflow   - This is one that simply opens and closes the flow of water through the sink drain. Visualize a regular sink without a second hole at the top of the bowl and you'll imagine a classic waste valve without an overflow. This option is easy to install, reliable to use and does not raise any additional questions.

Let's move on tovalves with overflow . They are equipped with an additional hole in the upper part of the sink - an overflow, which serves as an “overflow”. When the water level in the sink becomes too high, such as when a faucet is left open, water begins to flow through the overflow, preventing spills and overflowing.

When choosing between a foot valve with or without an overflow, several important factors should be taken into account:

• If your priority is to avoid the possibility of your sink overflowing, especially if you have children or are forgetful, then an overflow valve may be your best choice.
• Don't forget about the visual aspect. An overflow can change the appearance of a sink and give it a modern or classic look depending on the design.

Non-overflow foot valves are often more affordable and less difficult to install, but this may vary depending on the model and manufacturer. So, when choosing between a pop-up valve with or without an overflow, consider your needs, design preferences, and budget. Both options have their benefits and can be an ideal choice for your bathroom or kitchen.
