One of the most important parts of a pressure washer is the hose. These hoses are designed to function under extreme pressures and should never be compared with a standard garden hose. Composed of several layers, a pressure washer hose has a network of threads running through its length to make it extremely strong. These hoses should be replaced at any sign of damage, including cracks, bulges an leaks from the connectors. Replacing a hose is actually quite easy one you know what thread you need. This also gives you the opportunity to buy a longer hose to expand your operating range. Immediate replacement of a damaged hose is very important in preventing injury caused by high powered spray.
Replacing a Hose
There are several things to look for in pressure washer hoses to determine damage. Water spraying out the sides of the tube, bulges in the plastic, cracks and leaks from the hardware are some of the things to keep in mind each and every time you turn the machine on. During replacement, refer to your user’s guide to determine the diameter and threading of your current hose. Finding a replacement then becomes easy.
Hose Care and Selection
- Always select a new hose which can work in the operating temperature of your machine. An under rated hose can become brittle when exposed to water that is too hot.
- Never drag a hose over materials that are too hot. Protecting the exterior of the hose is just as important as protecting the inside. Laying the hose outside in the hot sun or next to a heater is not recommended.
- Chemical injection cleaning can only be done on a hose which is rated for chemical resistance.
- Keep in mind that the pressure washer hose will be subjected to pulse shortening while under pressure. You need to accommodate for this change in length when selecting the right length of hose.
- When connecting more than one hose together, consider installing spring guards to ease the strain at these joints.
- Never use a garden hose or any hose that is intended for a use other than pressure washing.
- Drain the hose after every use and flush them thoroughly after a chemical cleaning.
- Always use a hose reel or rack to store your hose- never a peg or nail.
- Bring your hose inside when the temperatures get below freezing. This prevents cracking caused by brittle material.
