This pump needs to be supplied with a 1.5" non-collapsible suction hose (agc24) and a 1.5" y-strainer with an 80 mesh ss filter. The jump hose from the unloader must be 1/2" id and the first 50' minimum off the reel must be 1/2" id (505040blk). Consider upsizing the hose on your surface cleaner to 3/8IDid for increased speed and efficiency.  We understand that these pumps are often supplied with a 1" hose barb. Since you spent the money going to 8 GPM, ensure that you have spent it wisely by plumbing this GPM pump for maximum output.  


66 series triplex plunger pump 



  • Forged brass manifold with an exclusive lifetime warranty. 
  • Innovative seal design to extend seal life.
  • Plunger design improves thermal shock resistance. 
  • The new valve cap design improves hydrostatic performance.
  • 8.5 GPM maximum 
  • 3600 psi maximum
  • 1750 rpm maximum 
  • 165 f maximum temperature 
  • 24mm shaft diameter 
  • Inlet port: 3/4" FPT 
  • Discharge port: 3/8" 
  • FPT crankcase capacity: 31 oz 
  • Weight: 40 lbs. 

*** The supply/suction hose inner diameter (id)should be doubled compared to the pump inlet/suction port. For example, the general pump ts2021(hp5535) has a 1/2" inlet on either side of the bottom manifold of the pump. The pump should be supplied with a 1" non-collapsible suction hose. 


Have you ever wondered how to correctly plumb your power washer? 


Pressure washer products love to share knowledge. Mount the pressure washer as low to the surface as possible about the supply port/bulkhead of the water tank but remember to use shock-absorbing rubber pucks (part# 4542) on your skid l-brackets of the pressure washer. Most pressure washers can be converted from carts with wheels to skid units by removing the wheels and installing l-brackets for your unit available through us. 


Minimize the use of extra fittings. Do not use galvanized fittings or metal ball valves between your pump and water tank because they will likely corrode and flake little chunks into your pump valves leading to vibration and/or damage. Avoid extra elbows. Do not use PVC pipe anywhere. PVC pipe can become brittle and doesn't tolerate the weight of a surface cleaner, ladder, or your body weight for long. If not installed correctly, air will find its way into your pump leading to manifold damage. Install components using non-drying liquid Teflon and never use Teflon tape. Never adjust your unloader. The unloader should be set using a whip hose, high-pressure ball valve, high-pressure steel tee, snubber, and gauge to 200 psi above the operating pressure of the pump and left alone. Do not install check valves or any type of swivel fitting on the suction/supply hose assembly or air may become entrained causing extensive damage from cavitation. 


Working with a non-collapsible hose can be challenging.  We have the luxury of having several heat guns and ratcheting PVC hose cutters to tame the hose. When installing the hose into hose barbs, first slide the hose clamp a few feet away from the cut end. Grab some slo-mo soft wash surfactant for sodium hypochlorite, dish soap, or shampoo, and coat your finger or old toothbrush with a generous amount. Apply the soap to the inside several inches and the barbed end of the hose barb. Turn on the heat gun and hold the heat source about 3-4" away from the hose end while rotating the hose as you try to apply the heat as evenly as possible. Heat only until the hose turns shiny and releases a single plume of smoke. Turn off the heat gun and set it aside to cool. Install the barb into the hose end and push it down against the ground or vertical surface. Allow the end to cool naturally, move the hose clamp up about 1/16" or 1/8" from the end toward the thread, and tighten securely. Install the hose clamp to allow you to access it easily in the future so that you do not have to struggle to use a tool on the clamp. 


The unloader bypass hose that sends water back to the tank when you release the trigger on your gun should be installed using a 3/8" or 1/2" kink-resistant hose. The port should be installed so that the stream of water shooting into the tank does not point directly at the pressure washer suction/supply bulkhead. You don't want to create air bubbles in your supply of water. The bypass hose running back to your tank will act as a backup for your thermal relief valve mounted on the opposite side of your pump to the suction hose assembly.


A few words about the high-pressure side of the pump.


Do not use Teflon tape on any fittings. Use medium, removable thread lock (5003, 10 ml, or 5004 50ml).  Try not to use elbows or extra fittings. When at all possible, minimize the use of quick connects. Install the chemical injector at least 3' away from the unloader to prevent back-siphoning of chemicals into the internal components of the unloader. Always remove the chemical injector assembly when not in use. You can install a chemical injector bypass kit with a high-pressure 3-way ball valve. Only use the bypass kit that allows high pressure straight through instead of losing pressure by taking turns through two high-pressure tees and multiple quick connects. The chemical injector should be installed on the bypass side of the chemical injector bypass kit. 


Use a r2 or 2-wire jump hose on the high-pressure outlet of your unloader to your reel. 


Before purchasing a telescoping wand, try out some long-range nozzles such as 002, 0025, 0030, 0035, 0040, 0050, and 0060 installed into female plugs. To improve your vertical reach with these nozzles, use them with a 6', 7', 8', 10', or 12' aluminum wand and a side handle (1536) for added control. 


When using 8 GPM or more, use a 1/2" ID high-pressure jump hose to your reel, use 50' of 1/2" ID high-pressure hose coming off the reel, and replace the 1/4" ID high-pressure hose on your surface cleaner with a 3/8" id. We can custom cut and crimp your high-pressure hose to your desired length and ship it to you.
