What to do if my VERDER Water Pump won't cycle or stops after one cycle?
- J
  Jennifer Gutierrez DVMAug 12, 2025
  If your VERDER Water Pump fails to cycle or stops after a single cycle, several issues could be the cause. The air valve might be dirty, leaking, or blocked, so replacing or cleaning the air valve is recommended. The valve ball may be stuck, in which case you should replace the valve balls and/or seats. Other potential causes include icing of the muffler or air valve (improve air quality), insufficient air pressure (check the air supply system for blockages or leakage, or increase the air supply), a closed discharge or suction line (open the valve and check for blockages), or a diaphragm rupture (replace the diaphragms and clean the pump).

Why is my VERDER Water Pump operating erratically?
- R
  rmckinneyAug 16, 2025
  Erratic operation of your VERDER Water Pump can stem from several causes. The suction line might be clogged (check suction line). The check valves could be sticky or blocked, requiring cleaning or replacement. A diaphragm rupture could also be the cause, so replace the diaphragms and clean the pump. Additionally, a restricted exhaust (remove restriction and when necessary replace muffler) or a leaking or blocked air valve (replace air valve) can lead to erratic pump behavior.

How to fix insufficient discharge pressure in my VERDER VERDERAIR PURE?
- J
  Justin RaymondAug 20, 2025
  Insufficient discharge pressure in your VERDER Water Pump can be caused by several factors. Not enough air pressure is a common cause, so increase compressed air pressure or check if other components are consuming too much air on the same compressed air line. An air supply leak can also be responsible, so check and repair any leaks. Also check for worn check valves (replace check valves) or a leaking air valve (replace air valve).

Why is the discharge decreasing in my VERDER Water Pump?
- H
  huntamyAug 25, 2025
  A decrease in discharge from your VERDER Water Pump can occur for several reasons. Other components may be consuming too much air on the same air supply line (increase the volume of air). The air supply may be reduced (check air supply system for blockage and/or leakage). The suction or discharge strainer might be blocking (clean suction strainer or clean discharge strainer). The medium may have become more viscous (check why and if necessary adjust pump settings), or the muffler could be blocked (clean out or replace, and check on icing!).

What to do if my VERDER VERDERAIR PURE Water Pump is running but has insufficient suction?
- C
  carrie44Aug 27, 2025
  If your VERDER Water Pump is running but lacks sufficient suction capability, several factors could be responsible. The pump may be running too fast (start-up pump slow running, and once filled with liquid, you can run it faster). Cavitation could be occurring (check suction condition and adapt when necessary). The suction strainer may be blocking (clean suction strainer). The suction line might be closed (open valve in the suction line and/or check on blockage). There could be worn check valves (replace worn parts) or a leak in the suction line or connections (repair and make leak tight).

Why are there air bubbles in the fluid from my VERDER Water Pump?
- G
  grogersAug 31, 2025
  If you notice air bubbles in the fluid from your VERDER Water Pump, it could be due to a few reasons. The suction line might be loose (tighten). A diaphragm rupture could also be the cause, so replace the diaphragms and clean the pump. The suction container might be empty (fill or replace suction container), or cavitation could be occurring (check suction condition and adapt when necessary).

Why does my VERDER Water Pump cycle at stall or fail to hold pressure?
- K
  kristinehunterSep 3, 2025
  If your VERDER Water Pump cycles at stall or fails to hold pressure, the likely cause is worn check valves and/or o-rings. Replace worn parts to resolve this issue.

Why is there fluid in the exhaust air of my VERDER Water Pump?
- G
  Garrett WalkerSep 8, 2025
  If you find fluid in the exhaust air of your VERDER Water Pump, this is most likely due to a diaphragm rupture. Replace the diaphragms and clean the pump.
