How to Repair a Cracked Pressure Washer Pump

If you are wondering how to repair a cracked pressure washer pump, this article will give you some tips. Before you start, ensure that you have the right equipment. Clean the pump thoroughly and make sure that it’s leveled. Next, you’ll need to replace the o-rings and pistons. If you’re able to find the exact pump assembly, you can purchase it at your local dealer or online.

If you notice that the pump oil is leaking, it’s time to replace the o-ring and ceramic plunger. The o-ring is the gasket that seals the pump to the high-pressure hose. Water can leak through the seal and cause problems with the pump’s performance if it is damaged or cracked. In such cases, it is important to replace the o-ring as well as the coupling. This is an easy and inexpensive repair that you can do yourself.

You can hire a professional if you aren’t confident with your DIY skills. A cracked pressure washer pump can result from a number of factors, including a water freeze. The frozen water can cause a crack in the pump’s seal and compromise its ability to pressurize water. A cracked pump should be replaced as soon as possible. A new pump will be required if the old one is damaged.

First, you need to remove the pump. You must ensure that the oil is not leaking. This could be caused by loose fittings or pushed-off check valve cap caps. These issues can lead to water leaking from your pump, which can cause a chattering sound. You should also inspect the seals and o rings of the pump. This is the easiest way to ensure that the pump’s performance is not compromised.

The hose and outlet seals are another common problem with pressure washer pumps. These are responsible for pumping water through a hose at high pressure. These seals can crack or become brittle and cause problems with your pump. You will need to replace the seals if they are damaged or worn. You can’t use your pressure washer when it leaks.

The first step is to disconnect the water and electrical components that are attached to the pump. This can be done with a wrench. You’ll also need an Allen head bit and a ratchet. Using a ratchet, you can loosen the bolts. You can then slide the pump off with the hose. You can then remove the hose and check the connections.

The next step is to check the oil level. Make sure that the level isn’t cloudy, as this means water has mixed with the oil. This can be replaced if you don’t have it. Depending on the model, you may need to replace the entire pump to fix the problem. If it’s the hose, however, you can use a siphon to remove the cloudy oil from it. You can apply primer to the pump and reattach it if it is still not working.
