Have clean rags and a parts tray ready.\u003c\/p\u003e\n\u003cp\u003eWhen replacing seals and packing, lubricate them with pump oil or silicone grease before installation. Dry seals tear on first startup. Check plungers for scoring or wear marks. A scored plunger will chew through new seals in hours.\u003c\/p\u003e\n\u003cp\u003eUse the correct pump oil. Check your pump manufacturer's recommendation. Most triplex pumps use non-detergent pump oil (not motor oil). Change the pump oil every 200 to 500 hours or at the start of each season.\u003c\/p\u003e\n\u003cp\u003eAfter reassembly, run the pump with water flowing and no pressure for 30 seconds to prime it and seat the seals.

Other symptoms include water leaking from the pump head, pulsating pressure, unusual noises, and oil leaking from the crankcase.

Seal kits, valve kits, and packing sets cost a fraction of a new pump. The pump body and crankcase last for years if you maintain them. The only time to replace is if the crankcase or manifold is cracked.\u003c\/p\u003e\n\u003ch3\u003eHow often should I rebuild my pressure washer pump?\u003c\/h3\u003e\n\u003cp\u003eIt depends on hours of use. Most commercial washers rebuild pumps every 500 to 1000 hours. Replace seals and valves when you notice pressure loss or leaks.

Disconnect the engine or motor from the pump. Have clean rags and a parts tray ready.\u003c\/p\u003e\n\u003cp\u003eWhen replacing seals and packing, lubricate them with pump oil or silicone grease before installation. Dry seals tear on first startup. Check plungers for scoring or wear marks. A scored plunger will chew through new seals in hours.\u003c\/p\u003e\n\u003cp\u003eUse the correct pump oil. Check your pump manufacturer's recommendation. Most triplex pumps use non-detergent pump oil (not motor oil). Change the pump oil every 200 to 500 hours or at the start of each season.\u003c\/p\u003e\n\u003cp\u003eAfter reassembly, run the pump with water flowing and no pressure for 30 seconds to prime it and seat the seals. Then slowly bring it up to operating pressure and check for leaks.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat are the signs that my pump parts need replacement?\u003c\/h3\u003e\n\u003cp\u003eLoss of pressure is the most common sign. Other symptoms include water leaking from the pump head, pulsating pressure, unusual noises, and oil leaking from the crankcase. If you notice any of these, inspect and replace the worn parts before the damage spreads.\u003c\/p\u003e\n\u003ch3\u003eShould I rebuild my pump or buy a new one?\u003c\/h3\u003e\n\u003cp\u003eIn most cases, a rebuild is cheaper and gets you the same performance as a new pump. Seal kits, valve kits, and packing sets cost a fraction of a new pump. The pump body and crankcase last for years if you maintain them. The only time to replace is if the crankcase or manifold is cracked.\u003c\/p\u003e\n\u003ch3\u003eHow often should I rebuild my pressure washer pump?\u003c\/h3\u003e\n\u003cp\u003eIt depends on hours of use. Most commercial washers rebuild pumps every 500 to 1000 hours. Replace seals and valves when you notice pressure loss or leaks. Preventive rebuilds at the start of each season keep you from breaking down on a job.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer pump parts near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.

Disconnect the engine or motor from the pump. Have clean rags and a parts tray ready.\u003c\/p\u003e\n\u003cp\u003eWhen replacing seals and packing, lubricate them with pump oil or silicone grease before installation. Dry seals tear on first startup. Check plungers for scoring or wear marks. A scored plunger will chew through new seals in hours.\u003c\/p\u003e\n\u003cp\u003eUse the correct pump oil. Check your pump manufacturer's recommendation. Most triplex pumps use non-detergent pump oil (not motor oil). Change the pump oil every 200 to 500 hours or at the start of each season.\u003c\/p\u003e\n\u003cp\u003eAfter reassembly, run the pump with water flowing and no pressure for 30 seconds to prime it and seat the seals.

Other symptoms include water leaking from the pump head, pulsating pressure, unusual noises, and oil leaking from the crankcase. If you notice any of these, inspect and replace the worn parts before the damage spreads.\u003c\/p\u003e\n\u003ch3\u003eShould I rebuild my pump or buy a new one?\u003c\/h3\u003e\n\u003cp\u003eIn most cases, a rebuild is cheaper and gets you the same performance as a new pump. Seal kits, valve kits, and packing sets cost a fraction of a new pump. The pump body and crankcase last for years if you maintain them. The only time to replace is if the crankcase or manifold is cracked.\u003c\/p\u003e\n\u003ch3\u003eHow often should I rebuild my pressure washer pump?\u003c\/h3\u003e\n\u003cp\u003eIt depends on hours of use. Most commercial washers rebuild pumps every 500 to 1000 hours. Replace seals and valves when you notice pressure loss or leaks.

Disconnect the engine or motor from the pump. Have clean rags and a parts tray ready.\u003c\/p\u003e\n\u003cp\u003eWhen replacing seals and packing, lubricate them with pump oil or silicone grease before installation. Dry seals tear on first startup. Check plungers for scoring or wear marks. A scored plunger will chew through new seals in hours.\u003c\/p\u003e\n\u003cp\u003eUse the correct pump oil. Check your pump manufacturer's recommendation. Most triplex pumps use non-detergent pump oil (not motor oil). Change the pump oil every 200 to 500 hours or at the start of each season.\u003c\/p\u003e\n\u003cp\u003eAfter reassembly, run the pump with water flowing and no pressure for 30 seconds to prime it and seat the seals. Then slowly bring it up to operating pressure and check for leaks.\u003c\/p\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat are the signs that my pump parts need replacement?\u003c\/h3\u003e\n\u003cp\u003eLoss of pressure is the most common sign. Other symptoms include water leaking from the pump head, pulsating pressure, unusual noises, and oil leaking from the crankcase. If you notice any of these, inspect and replace the worn parts before the damage spreads.\u003c\/p\u003e\n\u003ch3\u003eShould I rebuild my pump or buy a new one?\u003c\/h3\u003e\n\u003cp\u003eIn most cases, a rebuild is cheaper and gets you the same performance as a new pump. Seal kits, valve kits, and packing sets cost a fraction of a new pump. The pump body and crankcase last for years if you maintain them. The only time to replace is if the crankcase or manifold is cracked.\u003c\/p\u003e\n\u003ch3\u003eHow often should I rebuild my pressure washer pump?\u003c\/h3\u003e\n\u003cp\u003eIt depends on hours of use. Most commercial washers rebuild pumps every 500 to 1000 hours. Replace seals and valves when you notice pressure loss or leaks. Preventive rebuilds at the start of each season keep you from breaking down on a job.\u003c\/p\u003e\n\u003ch3\u003eWhere can I buy pressure washer pump parts near Gaithersburg, Maryland?\u003c\/h3\u003e\n\u003cp\u003eSun Brite Supply is located at 16620 Oakmont Ave, Gaithersburg, MD 20877.
