1. In the hydraulic cleaning of fluid reservoirs, said reservoirs having a fluid circulating system, comprising in sequence reservoir, reservoir drain line, pump, filter and return line, interconnected to each other:

  • (A) plural, extensible and retractable, open-end flexible conduits removably housed in walls of the reservoir, said conduits each having a pressure-responsive head fixed to ends thereof, responsive to the flow of fluids therethrough, to extend and retract said conduit means into and out of the fluid reservoir, for submersible fluid injecting interruption contact with each other;

    (B) a valve assembly having in-line valves interposed within the fluid circulating system, comprising multichambered control to regulate modes of;

    first, normal filtering run of the reservoir with retracted conduits;

    secondly, cleaning and filtering same with extended conduits and thirdly, retracting the conduit means, precedent to return to normal run;

    (B

         1) a first of said valve assembly having as single control stem, said first valve interconnecting reservoir, pump return and conduits, said valve connecting the reservoir return and pump in the normal run and connecting to open end conduits in the cleaning mode;

    (B

         2) a second of said valve having a single control stem, interconnecting the conduits, drain and pump, whereby upon coordinate actuation of the respective valves the three modes of operation may be effected;

    whereby the volume and pressure applied to the conduits may be selectively controlled to effect the speed of extension for retraction and the distance of extension thereof.
