The housing has a first side for attachment of hoses to the hose nozzles and a second opposite side has openings which allow tips of the hose nozzles to extend out of the housing for the discharge of water. A diffuser may be attached rotatably to the second opposite side, allowing the diffuser to open and close to access the interior of the diffuser. A first portion of a trailer hitch is attached at a front end of the housing and a second portion of the trailer hitch is attached rotatably to the first portion so that the system can be rotated vertically for transportation by a vehicle or by an attachable wheel. The system is small, portable, stable, easy to use and maintain, and a user has control over where discharge water is flowing. ## Claims ### Claim 1 A portable apparatus for testing high pressure water systems, said apparatus comprising: a) a housing having a housing top, a housing bottom, a housing front, a housing rear, a housing first side and an opposing housing second side;
