• Power Supply (Not too low when using long leads on 240 Volt units)
• Suction Filters (Blocked?)
• 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.
