The TOTO spare “B5071” is part of the toilet tank internal mechanism, similar category as the B3835E you asked earlier—but usually from a different model series / assembly code.

🔧 What is B5071 (TOTO spare)?

• Code: B5071
• Category: Fill Valve / Inlet Valve assembly (tank fitting)
• Used inside: TOTO toilet cistern (tank)

👉 In simple words:

It is the component that fills water into the toilet tank after every flush.

🚽 Main uses of B5071

1. Tank refilling

• After flushing, B5071 opens automatically
• Refills the tank with fresh water

2. Automatic water stop

• Stops water once the tank reaches correct level
• Prevents overflow and wastage

3. Maintains flush performance

• Ensures correct water quantity for next flush
• Directly affects flush pressure & efficiency

⚙️ Where B5071 is used

• TOTO one-piece toilets
• TOTO two-piece toilets
• Concealed tank systems

🔄 When to replace B5071

You should replace this part if you notice:

• 💧 Water keeps running continuously
• 🚰 Tank not filling or very slow filling
• 🔊 Hissing or noise from tank
• 🚽 Weak flush (due to low water level)
• ⬆️ Overflow into pipe

These issues are typical fill valve failure symptoms.

🧩 How it works (simple system view)

Inside a toilet tank:

• Fill valve (B5071) → fills water
• Float → detects water level
• Flush valve → releases water when flushing

👉 B5071 = “water entry + control system”

👍 Key benefits

• Saves water by stopping at correct level
• Maintains consistent flush performance
• Reduces leakage problems
• Easy replacement without changing full toilet

⚠️ Important installation tips

• Always shut off water before replacing
• Do not overtighten plastic fittings (can crack)
• Adjust water level to tank marking
• Avoid harsh chemical cleaners inside tank (they damage parts)

🔁 Compatible / alternative fill valves

If B5071 is unavailable, similar TOTO-compatible fill valves are used as replacements:

• TOTO TSU99A.XR Universal Fill Valve
• Korky Genuine TOTO 528GT Fill Valve

These serve the same function (tank filling) but compatibility depends on your toilet model.
