Water supply volume (Not too low)
As a guide in normal use, consider the following:
-
After replacing 10 x high pressure Stainless Steel jets/nozzles, it is time to replace the
seals on the pump using a Seal Kit.
-
At the same time, also replace the seals on the By-Pass Valve using a By-Pass kit, or if
economically viable, replace by-pass valve.
-
By-Pass Valves will take 3-5 rebuilds before body wear becomes too much and
replacement is needed.
-
Do a whole pump changeover at 1,000 – 1,200 hours. (Con Rods, Big Ends & Crankshaft)
-
Pistols, swivels & H.P. Hoses are usually uneconomical to repair. Replace as necessary.
Remember to check filters regularly and clean under running water.
The correct procedure for replacing the filter mesh in the small black filters (vs the large grey
filters) is to first put the mesh into the cup after rinsing under running water and then screw it
back onto the filter head. This is the opposite of replacing the filter mesh in the large filters.
Correct procedure of replacing LARGE filter cartridges on large grey filters:
•
Always put the filter mesh tube into the black ‘head’ first (the part mounted on the frame)
ensuring it is square and tight.
•
Now screw on the grey cup part of the filter.
Doing it the opposite way may result in a crushing of the filter mesh!
