Frequently Asked Questions - 5251 Sani-Lav

What is the Sani-Lav 5251?

The Sani-Lav 5251 is a hands-free wall mount stainless steel sink designed for commercial use, featuring a single knee pedal valve for touchless operation and a swivel gooseneck spout.

How do I install the sink?

Install by marking the wall level, mounting the bracket, positioning the sink, securing it, connecting the drain and water supply (hot and cold), and flushing the system before use. See the manual for detailed steps with illustrations.

What tools are required for installation?

Tools included: tape measure, adjustable wrench, drill motor and bits, pipe wrench, level, safety glasses, screwdrivers (phillips and standard), pencil, and socket wrench.

How do I fix a water drip from the spout?

A drip from the spout usually indicates a worn flat washer on the stem/plunger. First determine if the leak is from the hot or cold side by shutting off cold water. Then replace the affected valve component using a valve repair kit (e.g., part 1061L or 1061S).

How do I repair a water leak from the front of the valve?

Leaks from the front of the valve indicate worn O-rings on the plunger. Visually check which side (hot or cold) is leaking and replace the threaded insert, plunger assembly, and spring using the repair kit. The valve can be repaired without disconnecting from the sink.

How do I clean the stainless steel sink?

Clean with an abrasive cleaner like Bon-Ami or Zud, scrubbing in the direction of the grain. Alternatively, use baking soda. Rinse thoroughly with hot water and dry to prevent water spots and corrosion. Avoid harsh abrasive cleaners and scouring pads.

What should I avoid when cleaning?

Avoid harsh abrasive cleaners, corrosive chemicals, scouring pads, carbon steel brushes, steel wool, oily rags, and mixing cleaners. Never use solvents in enclosed spaces or while smoking.

Are replacement parts available?

Yes, a wide range of replacement parts are available, including pedal assemblies (1041-1043), nuts and bolts (1049-1052), threaded inserts (1053/1053S), plunger assemblies (1055/1055S), springs (1056), valve bodies (1057/1058), and repair kits (1061L/1061S).

Is the sink compliant with safety standards?

Yes, the sink is certified under NSF/ANSI 2 Food Equipment and NSF/ANSI 372 Low-Lead. It also complies with California Proposition 65, warning of exposure to chemicals like chromium, lead, and phthalates.

What is the recommended maintenance frequency?

Clean with an abrasive cleaner weekly or bi-weekly. Rinse with hot water after each use to prevent chloride-induced corrosion. Dry regularly to avoid water and surface rust marks.

Care and Maintenance

Regular cleaning will preserve the appearance and integrity of the surface. Stainless steel can easily be cleaned and kept stain-free using various methods.

Recommendations:

• Clean with an abrasive cleaner like, Bon-Ami or Zud weekly or bi-weekly. Always scrub in the direction of the grain or polish lines. Another option is to use Baking soda. Make sure to rinse well and dry. Illustration A
• Most soaps and detergents contain chlorides, we recommend rinsing the stainless-steel sink with hot water after use, to prevent corrosion. Illustration B
  • Regularly dry your sink to prevent water and surface rust marks. Illustration C
• Do not leave salt in the sink or near a saltwater environment.
• Use a quality stainless steel cleaner and follow cleaner instructions. Wipe along the grain (NOT against). Illustration D

Things to Avoid:

• Avoid harsh abrasive cleaners and corrosive chemicals.
• Avoid abrasive scouring pads, carbon steel brushes and steel wool for cleaning as iron particles left behind can lead to rust.
• Avoid the use of oily rags or greasy cloths when wiping the surface. To avoid water spots, wipe dry after use.

Additional Tips:

• Regularly drying your sink works wonders to prevent water and surface rust marks.
- Wear rubber gloves when working with cleaners to protect your hands.
- Never mix cleaners. Some products react to create dangerous gases.
- There are thousands of blended or compound cleaners on the market. Users are advised to contact suppliers of solvents for information on their applications on stainless steel.
• DO NOT USE SOLVENTS in closed spaces or while smoking.
• Note: Columbia does not recommend use with harsh chemicals.
