Buying Guide: Key Considerations for Toilet Supply Lines
- Length: Measure the distance from the shut-off valve to the toilet tank inlet. Common lengths are 6″ and 12″. Choose a line that allows for some slack to avoid tension.
- Fitting type: Most toilets use 3/8″ compression on the valve side and 7/8″ ballcock threads on the toilet side. Confirm the exact thread sizes on your valve and tank to ensure compatibility.
- Material and durability: Braided stainless steel offers strength, corrosion resistance, and flexibility. Avoid lines with thinner or plastic sheathing in high-use bathrooms.
- Flexibility and routing: If space is tight, select a line described as flexible or with a no-burst design. Consider extensions only if needed to reach difficult configurations.
- Number of toilets: For households with multiple bathrooms, a bulk pack can reduce future replacements and simplify stocking.
- Installation effort: Look for lines that require minimal tools and provide clear installation guidance. No-plumber setups are ideal for DIY replacements.
