Leaking Valve

• 1). Switch the sump pump on.
  
  
• 2). Confirm it is a true leak and not just condensation running down the pipe.
  
  
• 3). If there is strong evidence of a leak, switch off the pump.
  
  
• 4). Tighten the clamp holding the valve in place, using a screwdriver.
  
  
• 5). Switch the pump on again and see if the leak persists. If it does, switch off the pump. Remove the clamp and valve and follow Step 6.
  
  
• 6). Take a small amount of special putty used by plumbers to stop leaks. Spread it thinly around the valve's thread. Push it into the thread with your forefinger and re-assemble it.
  
  
• 7). After the putty has dried, put the valve and clamp back on the pipe.
  
  
• 8). Switch the pump on again and check for leaks.
  
  

Noisy Valves

• 1). Switch the pump off and unplug it.
  
  
• 2). Remove the existing check valves by unscrewing the clamps.
  
  
• 3). Examine each valve closely for fine silt and grit clogging up the entrance around the lid.
  
  
• 4). Wash away debris under a running tap. If the valve lid opens and closes properly, re-attach it to the pipe.
  
  
• 5). If the valve is already clean, replace it with a noiseless one.
  
  
• 6). Replace any damaged or swing door valves with noiseless ones.
  
  
• 7). If the noise continues, replace any original valves with noiseless ones and retest.
