Bidet water supply lines must be minimum size and type of

• A. 3/4 inch cold and hot
• B. 1/2 inch hot only
• C. 3/4 inch hot and cold
• D. 1/2 inch cold and hot

Answer: (C)

Bidet supply lines must provide enough water flow for both the spray and any built‑in heater, so they’re sized larger than many other fixtures. Using 3/4 inch lines for both hot and cold ensures there’s enough volume and minimizes pressure loss, delivering a strong, reliable spray and proper warm water availability. If you used smaller lines, such as 1/2 inch, you’d encounter flow restrictions that weaken the spray and can prevent hot water from being delivered adequately. That’s why the standard and best practice is to have both hot and cold supplies at 3/4 inch.
