The spray tip may be the most important part of the pressure washer. They range in size from 2.0 - 15.0. If the tip size is to big, you will experience pressure loss. The same thing happens if you move your thumb over the opening of a running garden hose. The bigger you make the opening of the garden hose, the less pressure you get.

Here is the calculation for nozzle size: SQRT(4000/PSI)xGPM or if you are unsure you can call us at(931) 268-4776 and we can assist you.

Cold water:

Cold water pressure washers can be used to successfully clean many objects and surfaces through a combination of impact of the spray and the application of cleaning chemicals and soaps. Cold water is generally used where grease and oil are not a factor, but with the right chemicals grease and oil can still be effectively dealt with.

Hot Water:

We know from washing dishes that hot water makes cleaning easier, especially if we are cleaning greases, oils, or petrochemicals. Cold water can only be as effective if the proper cleaning chemicals are also used. Hot water can often make cleaning faster by loosening dirt, gum, grease and oil. Most hot water units use diesel or kerosene to heat the pressurized water in a heavy duty heating coil. The heating coil and burner system makes the hot water unit much heavier, more complex and more difficult to maintain than a cold water unit. To run the burner system the unit requires electricity. So unless the unit uses a self-contained power source such as a battery or generator (Like our SC, SS and SM series) , you have to plug the hot water unit in (Like our HG, HD & HN series).

No. The first step in picking a pressure washer is determining how much performance you need to get the job done. How much pressure? How much flow? Do you need hot or cold water? Is gas, diesel or electric power better, safer, quieter, or cheaper. Once you have decided upon these factors, discussed in the other sections, you need to pick a product. Pressure washers with the same power plant will have similar performance, for example an 11 HP gas engine unit will typically produce at least 3,000 PSI and 4 gpm So it is often difficult to decide between different products except on price.Quality is what sets one pressure washer apart from another. Two pressure washers offered by two different manufacturers may have similar performance in terms of pressure and flow but will be quite different in terms of quality of components and unit configuration. They will also vary in price. When buying a pressure washer selecting the correct performance for the cleaning job at hand is just the first step. The second step is looking at the quality of construction and the quality of the components.

Hydro Tek machines offer advantages over other brands because of their quality construction. Hydro Tek uses stainless steel for all the control and safety panels. Our coils are wrapped in stainless steel to prevent rust. Our Ultimate Line uses the quieter, slower running, longer lasting belt drive pumps. We use stainless steel and heavy duty powder coated steel tubing to make our frames resist rust and outlast the competition. Our individual components are the best that market has to offer. We test all our components extensively before we allow them to become part of our machines.

When purchasing a pressure washer you should consider both the p.s.i. and g.p.m. of the machine. The p.s.i. or pounds per square inch, delivers the "punch" to a washing application and forces the contaminants from the surface. The g.p.m. or gallons per minute will flush the contaminants from the service. Choosing the right combination of p.s.i. and g.p.m. is the key to purchasing the ideal pressure washing system for your cleaning needs.
