Embodiments of a pump protection system are disclosed which may be used to enclose, protect, and improve the efficiency of a submersible pump. The pump protection system of the instant invention prevents unwanted materials from clogging the pump intake port and from entering the pump intake port to damage the internal parts of the pump. The pump protection system may be back flushed to clean the pump protection system without damaging the pump. The pump protection system also prevents entrained gasses from entering the pump. A pressure relief valve is also disclosed which provides back pressure on the pump and, thus, greatly reduces upthrust damage at pump startup.
