A common question asked by Hydra-Tech customers is:
Why is there a small stream of water flowing from the top cover of my pump?
There is a logical answer to this, and it is not that the pump is broken. Hydra-Tech Pumps manufactures one (1) of the four (4) bolts used to hold the water plate in place. This bolt has a 1/8″ hole through the center of it. The purpose is to allow trapped air to escape from the volute (pump body) when placing the pump into the liquid for the first time.
Maintenance: If this hole gets clogged, you simply just push a pick through the hole to clean out the dried up debris.
