  If the water box on your HydraMaster Test Equipment is empty or filling slowly, there might be a restriction in the water supply system. Inspect the supply system from the source through the incoming quick connect. Another possibility is a faulty float valve in the water box, so disassemble and inspect the valve, repairing or replacing it as necessary.

  If you're experiencing a weak vacuum at the wand of your HydraMaster Test Equipment, even though the gauge reads normal, there could be a blockage in the hoses or wand tube. Disconnect the hoses and check for an obstruction. Another potential cause is an excessive length of hose connected to the truckmount, so avoid attaching excessive lengths of hose.
