Question about what tips to use.

Hello everyone. I have a few questions about which tips to use. I have a house wash in 2 days and want to make sure I have my down streaming working properly. I have the downstream injector that came with my machine from the factory. I am unsure of the exact size and my unit is at storage but I will get the sizes first thing tomorrow. My machine is a 8 gpm hot/cold water pressure pro 3500psi. My question is, with the downstream injector that came with the machine, which tip would be best for pulling chem, and which will be best for rinsing? Also are the tips that come in a surface cleaner from the factory the recommended tips for a driveway? or should I be switching out the tips from the ones that came stock. Thank you in advance.
 
A #40 or #50 orifice is good for pulling chems ds. Look at ordering a jrod 4way nozzle holder and make one with all fan patterns and #50 orifice for spraying chemd. Be sure your spray gun is rated in the 12gpm range for best results. If you have much hose. ... over 50' I'd reccomend using the 2.1mm ds injector.
For rinsing houses I like the #40 or #30 orifice.

For your surface cleaner try a pair of 2504.5 for the bad concrete and the 4004.5 for not so dirty concrete and you'll be able to move faster. I've tried the 15 degree tips but they stripped more.
 
That's my main concern is being able to pull chem. I have plenty of hose to wash the house. ( I have 450 feet if needed). But I've looked at the house and should need no more then 150 feet. I am actually going to order a 4way nozzle holder as soon as I finish this post lol I have been meaning too. So correct me if I am wrong, but you are recommending applying chem with say, a white tip? and rinsing with a white or green tip?
 
Thank you for the links CL. Looks like I have some reading to do. I have a somewhat local pressure washing store, that may carry them I will have to call in the AM. If they don't ill be giving Bob a call. Quick question though, is downstreaming simply not possible with the tips I have on hand? The tips I have are just the stock ones that come with the machine.
 
Ask for 0040 or 0050 tip. (for Soaping High) then 2540 or 2550 (for soaping low.) For rinsing, follow the gude: 2510.

The tips that came with your machine won't help you downstream effectively enough...
 
If you had to, you could use the black soap tip that might have come with your machine but there are many companies making those and the orifice sizes are not consistent.

It comes down to personal preference, I like to soap with the 1540 (threaded nozzles, no color plastic guide on these so they fit into the 2, 3 or 4 nozzle holders that the vendors sell so all your nozzles are together) and for up high, I like to use the 0050 with the 8gpm or 5.6gpm machine. I also have the 2540 nozzle on the 3-way holder but hardly ever use it, these 2 are what I use on just about all the house wash jobs I do and they work great. No sense in buying tons of nozzles if you don't need them or will not use them.

For rinsing I like to use the same nozzles for low pressure but great rinsing flow so you don't blow mulch out of the flowerbeds, don't knock hanging stuff down, etc.....I have to go back to the trailer and pull the soap hose out of the soap container to use the same nozzles but that is ok, that is how I like to rinse. I usually put the hose into a container of water to rinse out the injector so they last longer, usually get about a year out of the injectors this way.

My machines are only 3000psi, you can use the same nozzles if you want to. The smaller the orifice, the more of a "mist" you will have with the 00 nozzles, the larger the orifice, the tighter the pattern and less mist to a point, then the larger you go, the less pressure and less distance you get. I don't go lower than 30 or 40 orifice for pulling chemicals, smaller and it will not pull chemical, too big and there is hardly any pressure.

Most of the vendors out there sell the same nozzles and holders, pick a vendor you like, some have minimum purchases, many don't.

The first 2 numbers are the fan pattern and the last 2 numbers are the orifice size, you can look on the nozzle charts to see how they lower pressure, just always go by your gpm's and psi to see what orifice you need for your machine. Downstreaming is different, no real chart made for this, just experience and help from the guys on the forums will help you but this is enough info for you to get started. I would order some General Pump Hi Draw injectors (non-adjustable) as they will go out on you when you need them most and hard to find good injectors locally, especially without spending 3 to 5 times the price.

Good luck.
 
THE 7-8 GPM KIT INCLUDES: 0060(SOAP HIGH),0020(RINSE HIGH),2560(SOAP LOW),2520(RINSE LOW)I think Im correct by saying each of these nozzles will pull soap. Injector will need to be removed for rinse

Great post as usual Pat & Chris. Pat curious why u suggest 4.5 tips for the scrubber with an 8gpm machine?
Im buying my first 8gpm@3000 this week
 
If his machine was 8x4000 psi then two 2504s would be correct. For 8x3500 its an 8.5 orifice so you really are supposed to use two 4.5s. Not sure what your 8x3000 will need. I suspect two #4.5s or one #9 for full pressure on the wand. But you need to check the nozzle charts it may be larger.
Since I run a lot of hose sometimes I do use #4s on my surface cleaner with my 8x3500 but it's really not by the book.

No your white tip is full pressure...too small an orifice to pull soap. The white tip is just a wide fan pattern.
Temporarily you can get some 1/4 brass hose barbs and use for a shooter tip and squish one in a vise a little for fan tips and use your black nozzle down low. You'll need a 1/4 qc adaptor to screw the barbs into.
 
You need to understand nozzles have two different measurements and a number that describes both. The first two digits are the fan pattern the last two digits are the orifice size. Orifice size controls pressure on the pump. To get full pressure you need an orifice 08.5 for your 8x3500 machine. Larger orifices drop the pressure and a 50 really pulls soap good for your setup although a 40 and even a 30 might on a good injector but it won't be a strong a mix as a 50 will pull. The pressure differential on the two sides of the injector is what makes it draw soap.

No. The rinse nozzles will not pull soap...at least mine don't. No need to pull injector hose.
 
Seriously thank you guys for all of the info. I did a ton of reading and took in everything you guys said. The semi local pressure washing store carries the tips you all have suggested. The lady I spoke to on the phone tried to sell me on other tips but I plan to take in a list and buy exactly what you guys have recommended. Again thanks for taking the time out of your day to help me.
 
Search this forum for a post I made called "nozzles tools of the trade" I'd put a link to it but I'm on my phone on Tapatalk now.
Just got home and I will search that post right now. The local store had a limited selection but I think I now have what I need for the time being. I picked up a 0040 for the higher stuff, and a 4040 for the lower soaping. I am going to go with what Chris said and go ahead and rinse with the same tips. I also picked up the 2 2504.5s Pat recommended for my surface cleaner. Also ordered a 4 way holder and 2 4004.5's
 
Good luck. The little plastic nozzles not really that useful for house washing. The 1/4 Meg spraying system nozzles are the way to go.
Just read through your post and there is a lot of great information there. I like the idea of having all the fan patterns as you suggested just incase a situation presents itself where they come in handy. I will be ordering a few more tips so I have a better selection and more options. Thank you for all your help and knowledge.
 
For starting id get a set of 50 or 60 orifice for soaping. A set of 30 for rinsing and a set of 8.5 for high pressure concrete work. Also get a turbo nozzle soon they are great for steps curbs etc....
