Pressure Washer Tips

See our Pressure Washer tips below from our in-house product expert to get the most out of your Pressure Washer purchase from TransNorth.

Tip One - Store the Pressure Washer in your Basement

In the spring, we frequently get calls from customers who tell us that their pressure washer worked fine last fall but does not produce any pressure this spring and leaks like crazy either from the bottom of the unit or from a hole in the hose.

These symptoms are caused when the pressure washer has been allowed to freeze (and unfortunately can be fatal for the pressure washer most of the time).

Here’s what happens.

After use, a small amount of water remains inside the pressure washer pump and hose – this is normal.  If the pressure washer is allowed to freeze, the water inside the pump/hose expands as it turns into ice.  The expanding ice puts tremendous outward pressure on the cast aluminum pump housing and or the steel-reinforced hose.  Most of the time, the pump housing cracks open &/or the hose bursts apart.

Aside from a small amount of water dripping out through the crack when the pressure washer thaws out, there are no symptoms of the damage until the pressure washer is used for the first time.  When the supply hose is connected and pressurized, water will leak out of the bottom of the pressure washer or from the hole in the hose.  If this happens to you, simply disconnect the water supply.  Do not start the pressure washer up.

If you have started the pressure washer and notice any of 1) leaking, 2) no pressure or 3) strange motor noise, shut the pressure washer off and disconnect the power and water supply. 

How to avoid?

If you live in an area where winter temperatures go below freezing, the best thing to do is to store your pressure washer in a heated basement where it won’t freeze.  We don’t recommend heated garages because they can easily go below freezing if the door is left open or the power goes out for a prolonged period.  Unheated garages, sunrooms, storage sheds, seasonal cottages, etc. are not recommended.

Tip Two - Optimal Cleaning Procedure

We recommend that you spray the detergent onto a dry surface. Do not pre-soak the area with water as wetting the surface first dilutes the detergent and reduces it’s cleaning ability.

To apply detergents, for most pressure washers you must be operating at low-pressure. This provides a gentle application of the detergent with the pressure equivalent to a garden hose. The high pressure setting is used for cleaning – you usually cannot apply detergents when working at high pressure.

Allow the detergent to remain on the surface for a short time (about 1-3 minutes) before rinsing – do not allow the detergent to dry.  If needed, use a brush to remove stubborn dirt.

Rinse with clean water under high pressure. On a vertical surface, with the nozzle 6-8 inches from the work surface at a 45 degree angle, rinse from the bottom up, then from the top down to avoid streaking. For best results, wipe the surface dry with a chamois or soft dry cloth.

When you are finished with the detergent, rinse the detergent bottle until it is thoroughly cleaned. Cleanout the suction system by inserting the siphon tube into the now clean detergent bottle filled with clean water. Siphon the water for about 2 minutes to ensure all the detergent is flushed through the pressure washer.
