2. Often we are called because people are having trouble priming a pump. Usually there is a air leak somewhere on the suction side of the pump. Even the most insignificant pin hole can be the culprit. The best way to find a small hole like this is to create a vacuum in the suction side then turn any noise off and listen. Another method is to put some water or other liquid over the suction hose or fittings and again listen for a leak and look for bubbles. Always be careful when storing your equipment since that is often the time when a small hole is created. In a worst case scenario your seals in the pump may be bad and need to be replaced. |
