Big Difference

JUst thought I would share my thoughts on how much of a difference, my new 8 GPM machine is compared to my 5 GPM, unbelievable, I washed a house, gutters patio etc.. on Friday the 1-2-04 this would take me normally over 4 hours, with my 5 GPM, I did it friday with my new 8 GPM unit in just over 2 hours, so I would have to say Volume makes a huge difference, Bob at
www.pressuretek.com built this monster from scratch, and it is more like a piece of art rather than a wash rig, I highly recommend any and all of his services, to anyone that is operating a PW biz, and wants to grow their knowledge and productivity...
 
did you have any water supply problems?

glad it works out for you,i have 2 6gpm machines on a trailer and it is all i can do sometimes to keep water,i would love to have more volume if i could myself.
 
Tim,
Why don't you couple them together? If I understand it correctly you will maintain same psi and double your volume to 12 gpm.

Downstream

Mike,
I washed a house Friday and downstreamed 6136 with very weak 3 month old chlorine, and it worked awesome, I didnt see a difference in the cleaning, other than being almost twice as fast, also I tested the downstreamer before using it and I got approx. 20% draw rate, which is standard percentage with downstreaming, if you look at all the downstreamers in all the catalogs they all claim approx. 20% draw rate, and I was getting that with 8 GPM and 200 ft of hi pressure hose, so I guess Im doing good, although, I have seen how people can misinterpret how that works, for example, if you have a 5 GPM rig,
you should be pumping approx. 1 gallon of soap/chlorine every minute, that would be 20% a 10 GPM machine would be pumping approx 2 gal. of soap/chlorine a minute, I guess it is all relevant, double the water, double the soap/chlorine, but what I have found is applying the soap/chlorine, is the easiest fastest part of washing, the hardest most time consuming part of any washing is the rinsing cycle which is normally 3-5 times longer, that is why I almost doubled my pump size, rinsing, rinsing, rinsing, this monster throws water on a side of a house like a fire hydrant, so my speed is almost doubled,
I cant imagine how fast I will get decks done with all this water, not to mention, doing alot less damage to the wood, using more volume and less pressure to get the same results, as this will be explained to my potential customers this year, which should be a huge selling point, and this is what the higher ups at Ready Seal Reccommend, more volume less pressure, get decks done twice as fast with less damage, therefore hopefully doubling my daily workload, in theory doubling my gross sales, not to mention cost cutting to the customer, if I can wash a house or deck, patio etc.. in half the time, I should be able to be very cost effective for the customer
 
good, I am glad you are sucking soap ok, that was one of my concerns when you got this rig. I am sure you love that extra flow, how does it feel on your arms compared to the old 5 gpm rig. I bet it feels much different. good luck with it.
 
Hello Rob.
I dont mean any disrespect but why be cost effective for your customers sake? unless your not already competative with what others are offering. I only say this because someones got to pay for this new machine and as long as you do the same quality of work in half the time as you use too, why pass this on to the customer? unless they are all repeat customers. I think this machine gives you more of an opportunity to increase your gross revenues without having to put in as many hours, as with the old machine, or to do more jobs making you more $$$ it sounds like a great machine keep us posted. foregive me if Iam off base here.

Not saying I would

Not saying I would cut my prices in half, but possibly a few % if I can get more work from it, we will have to see what happens next year..?
 
Tim,
The concept still applies. If one has need for a moderate psi high volume 10gpm machine then why foot the extreme cost of a high volume machine instead of simply coupling two inexpensive 4 or 5gpm machines?

i have 2 machines setup on a trailer,i use 2 man crews 90% of the time,if i am working alone one day what is the easiest way to couple the machines together (temporarily)

my earlier statement was i wish i could get the water to keep up with 2 8gpm machines on my trailer to increase our efficiency. but its all we can do sometime to get water to feed the 2 6gpm

i worked on New Years Day by myself and i can tell you it is much faster working 2 man crews from my standpoint.

to feed 2 men 8gpm each(with your concept) i would need 4 5gpm machines on a trailer plumbed together.
yes it would work and only cost $5,000.

i would have to hide it inside an enclosed trailer because i wouldnt want any of my customers to see the monstrosity.

Tim,
My response was in question form - "why not". I have seen this (Michael from Epps, etc) on various bbs and it makes sense to me. I am waiting to hear from someone who has actually done this - I may need to do this soon to run a spinner thru a long horizontal duct.

RJ, I have never done this, but I wonder if hooking two whip hoses, one from each machine to a high pressure "T" would work.
 
I think you should keep the majority of the savings to yourself..........but in certain situations, like when you REALLY want a certain job, you will have some room to play to lower your price........

Be careful not to overestimate the value of this equipment........I've made that mistake in the past with some other things. I think it is impossible for that machine alone to double your productivity. If I had to bet, I'd say 35% tops........but I wish you nothing but luck in proving me wrong!

Sounds like a nice machine.
 
8 gpm

I have only used 8 gpm machines. I also have a 10 and 12 gpm diesel rigs if anyone is interested. Water cleans and pressure destroys things. Buy a 300 gallon tote fill it with water from a garden hose and spray all day. Buy a larger gas tank, because the 24 hp honda's tend to use it up quicker. We are in FL and I inject all the time, clean 3000 sq ft home in 1.5 hours including the roof with two guys all day long. Just change the tips to lower the pressure issue. Have fun! 8 gpm at 3000 is the best combo for us. Jim
 
When attatching two machines together to gain GPM.Do they have to be the same PSI?
 
The type of unloader comes into play. I tried to hook together a machine with a k7 and a machine with a pressure actuated unloader and it didn't work out.
