Claim Text:
1. A method of increasing efficiency of a Y strainer having a filter cartridge receiving inflow through one end and outflow through apertures in a peripheral sidewall, the method comprising: slowing a velocity of fluids entering the filter cartridge of the Y strainer by having the fluids pass from a first portion of a first diameter into a second portion of a second diameter which is at least 50% larger than the first diameter prior to entering the filter cartridge, the filter cartridge being inserted into a filter cartridge receiving pipe in fluid communication with the second portion, the filter cartridge receiving pipe having the second diameter, wherein the filter cartridge has an inner sleeve with flow apertures and a flexible mesh filter which is retained between the inner sleeve and the peripheral sidewall; wherein the velocity of fluids entering the filter cartridge of the Y strainer is further slowed by positioning a deflector plate supported at an inlet end of the filter cartridge and extending into the filter cartridge at an acute angle to the inlet end of the filter cartridge such that a major portion of the fluids flowing along an inlet pipe strike the deflector plate and are deflected into the filter cartridge.
