There is a couple of different options. Some washers are equipped with pressure adjustment knobs. Failing that...all come with either multiple spray nozzles or twist type vari-nozzles. For multiple colored nozzles, the use of various widening angle-of-spray nozzles gives a range of impact force. The wider the nozzle angle, the lower the impact pressure on the substrate. Vari-nozzles do the same thing by twisting the housing. Most washers do have a pressure setting control. Look for a spring loaded assembly. Turning back the force exerted by the spring will lower your pressure setting. It is most commonly preferred to lessen the impact pressure by widening the impact area of the spray rather than lowering the pressure directly as it offers better productivity. Of course, pulling back the nozzle a few extra inches from the substrate surface can lower the pressure also.
On most professional pressure washers there is a pressure regulator on the pump. Usually by turning on way or other pressure will increase or decrease.
Water.
If you run hot water through the pump of a pressure washer, it will ruin the seals in the pump. The hot water causes their seals to swell, and the pistons will then rip them apart. Some machine are able to run hot water, but the have special seals inside. Ben - Great Lakes Cleaning Systems www.GreatLakesCleaningSystems.com
The inlet pressure can be as low as 45 PSI as long as there is a flow of about 3 gpm. The pump will easily pump it to 1500 psi through the appropriate nozzle
No, it most cases it it the GPM demand
Yes, bleach can be used in a pressure washer. Place the 12 percent bleach in the solvent hose in order to dispense the bleach with the water.
Basically, a pressure washer uses pressurization to deliver a concentrated spray of water or liquid. The force of this stream enables you to deep clean surfaces. But be careful what you use a pressure cleaner on - the force of the water can harm some surfaces. A pressure washer is a machine that pressurizes enough pressure to blast out a forceful spray of water that can deep clean an area and rid it of grime and mold. Pressure washers are used by painters to peel away paint from a house.
You can try to fish what ever is blocking the passage with a bendable tool or you can shut off the water valve and take the toilet outside and flush it with a high pressure hose something like a pressure washer.
In most there is a washer in them that has a small hole in it so that only so much water can get through regardless of how much pressure is behind it.
As the water heats up the washer in the tap, it expands. This causes the washer to partially block the open valve.
If you have a high efficiency washer then it should automatically adjust but if not then there should be a setting to adjust how much water you want based on your load size, therefor no water should be wasted.
If it has no pressure your problem should be on the pump. The three things I'd recommend you to check are: Packings, Unloader and Valve Kit.
you can adjust the pressure. for example water boils at a higher temperature in a pressure cooker.
