Down steam injection is where an injector is placed downstream of the pump and unloader (after pump). If you have a hot water unit it is placed after the heater. When the pressure on the line is dropped that causes the back pressure to be reduced within the injector. When the water flows through the injector nozzle it shoots across an internal chamber in the injector and creates an area of low pressure or vacuum (VENTURI). This allows the soap to be sucked up through the chemical line and mix with the water headed to the gun. When the pressure wash line is put back to a high pressure mode it creates back pressure in the line which fills the chamber and forces a check ball to be seated in the barb that prevents water from flowing back to the chemical tank.

Marco, I sent you a pm.

Are you looking for angle or 0 degree? For 0 degree you can drill out a 1/4" brass plug for a flatter fan try flattening out a hose barb. You will get a little angle but it won't be as nice as a machined one the manufactures make. I am surprised you would want to waste your time though most soap nozzles are only $3-6 from any of the vendors on the board and hardly ever wear out.

If you take the arms of the 4 nozzle surface cleaner and angle them back to get a greater rpm you are not really increasing your cleaning power. Any amount of flow that is taken away from the down force or impact of the water hitting the surface will reduce cleaning capacity. While a 0 degree nozzle may increase your cleaning force I would be careful in its use in a surface cleaner because it is so aggressive. Also with it being so close to the surface if you get hug up or stop for a second I can see the potential for damage becoming a problem. I would suggest nothing smaller than a 5 degree nozzle and even that may be a bit aggressive for some. Another issue to take into consideration is what rpm the swivels are rated for if you spin them too fast they may leak or wear out faster than usual.

I agree with you there, I always found the fords to be better plow trucks. I had a Yukon tat wasn't bad but by far the best was the F350/250 that I have. My personal one is an avalanche, TERRIBLE plow truck too many blind spots and the seat is sits too low for me, I like to be up to see better. ps. thats a lot of snow!

I agree more than 15 degrees is not helpful. The speed the arm spins is important to a point but if you set the angle too steep you loose the impact force on the surface that you need.

Driving a plow is fun, I've been doing it for over 28 years and I am still not tired of it.

You are always trying to make the wheel a little rounder aren't you Nigel. The grease is slowing the swivel because it is coming in contact with the bearings and parts of the swivel. once it wears off and breaks down it will spin more freely and speed up.

Prayers sent every day! They do deserve the highest respect an honor. Their sacrifice should never be forgotten or taken for granted.

Beer money? I guess they are trying to meet their payroll of $2.35 an hour.

Nice work, I like that color.

Big year for snow out east, not much so far here in Milwaukee.

Another great resource for the Roof cleaning is the RCIA board. http://roof-cleaning-institute.activeboard.com

Whoo Hoooo. Is this what it feels like to win Chris? Thanks to Ron for the great giveaway, now I just have to hide it from my kids.

I agree with Beth with lower flow rates like that you are really limited to residential work. If you do get a surface cleaner you will want one with wheels and probably no larger than 16" (for that machine) when you step up to 4-6 gpm then start looking at the 18-24 in cleaners.

Ya, my wife says the same thing to me to make me feel better. ha ha

I used my recovery deck and vac system on the tile at my building when my last tenant moved out. It was amazing the difference and very easy to do (easier than flat work). We will be doing some live demos in Milwaukee with recovery systems at the meeting in February. You should come down and see for yourself how easy it is. Sirocco makes one of the most flexible systems in the industry that would work well for all phases of recollecting work, Vacuboom is another option. Either of these systems will work very well for you and offer more for less money than a carpet cleaner system would.

It is quite an ordeal dealing with lead paint and asbestos. There is some good money to be made but it sure is a PITA. I agree with Tim I would just look elsewhere.

Way to go NCE has really come a long way.

It will depend a little on what you are cleaning. For Hoods the 4gpm or less is good, but for everything else I would stick with 5 gpm or more. In most cases you probably shouldn't go over 8 gpm as water may become an issue for you. If you have any specific questions feel free to call I would be happy to help you. 855-351-9274

It is definitely an economy killer.

But Beth, didn't you teach Rod everything he knows?

I would start by doing some searches on You tube. From that you can get an idea of many different ways to wash. Each application will have its own method so read up on it too. For example wood is low pressure 1500psi and lower and typically with a wide fan. Trucks will use a higher pressure usually between 1500-2500 and concrete will usually be 3500-4000 psi with heat.

Thanks Beth glad to be back.

That sounds like a good place to start. You may need to use a light degreaser to remove it. If that doesn't work you can try a light mix of oxalic acid.
