We have a Garage scheduled for Tuesday

Good luck Jim! Make it happen!

If you do have to run all the hose, just check your pressure at the pump. The gauge pressure leaving the pump is what the pump 'sees' - the pump doesn't know where the water is going or how much hose, just the pressure at the head.

With more hose you will get higher pressure at the same flow than you would through the shorter hose, but as long as you stay in range AT THE HEAD youre fine (a little higher than normal to make up for the extra drop at the end if you want) or run a little slower (less flow) to get your normal pressure - at the head - or run larger tips and keep the flow and pressure (less pressure at the end).
 
Jim you should be fine with the 1/2" hose and your pumps, they are rated at 4300psi, higher that most.

I wondered the other day if anyone runs 3/4" HP hose?

We gave a 27% discount for the senor citizens. That was before we learned that junior suite at this place gose for 1.2 mil with 4k a month in maintance fees.

If I new that, I would not of given a discount.
 
Why not use another shorter truck that has a winch and winch it in or use some tow straps and pull it in enough and then connect it to a different truck, you are just using the truck to pull it in and position it, not taking it on the highway.

Sounds like you need a short wheel base dually with low profile tires to get into these tight places, maybe some hydraulics to lower the body, make one truck a lowrider for these jobs.

I forgot, do you have jacks on all 4 corners or just the back? If you have them on all 4 corners then you could pull it in, connect with another truck and have a truck behind it to help push if needed to get it where you need it to be.
 
Trailer tug is by my home. They were the ones who backed off from the chanllege of getting our rig into the garage this week.

The second one sells for 18k and I thing is the best choice.

The third one has the best babe vote !

Jim what brand of degreaser do you use for those garages out west?? Do you ever just spray out the whole garage with a degreaser then let it sit of awhile and then Powerwash the deck or do you Spray Degreaser on just those real Greasy area's in the parking garage?
 
Why aren't you pulling that thing in with a four wheeler? They pull boats that weigh as much as your trailer around all the time?

When you're talking about just pulling something around a corner or up a little incline you chan throw towing capacities out the window.

I pulled a 22 thousand pound bucket truck over 10 miles with a strap behind a half-ton dodge gas pickup!!

It would work.

Then you could go out four wheeling on the weekends!! Yeeeee HaaaaW!
 
Tuff, I had a very difficult client. but we worked it out.

San Francisco is very...... well, San Franciscan. a little tooo liberal for my taste. We had allot of politics going on here. Something I am not a custom to.

And though we was going to attempt to fit the trailer thought this VERY tight fit, Upper management stopped us saying that it was too bid to enter the garage. So I had to get our sub contractors rig inside while mine ran from the curb to do any oil stains. It would of been great... I had the camera rolling folks. This was going to be a first, however I do understand the reasoning behind management decision for us not to proceed. If for some reason we did get stuck, I really do not know how we would off been able to get it out.

However, we do have another garage scheduled in a few months. 600,000+ sq ft. should take us about 7 to 9 working days to complete. This one has more than one exit and entrance. the problem here is the ramps are very narrow. I WILL be able to film this garage.

That makes alot of sense now why im only seeing around 2200psi at the tip after 300ft of hose on an 8gpm machine. I have herd that it will loose 100psi for every 100 ft of hose however I ahve seen alot of difference from whats said. Thanks for posting this
 
I have always heard around 100psi loss per 100' with the 3/8" hose but recently I read more like 138psi loss per 100' of 3/8" hose.

I know a few guys that switched over to 1/2" hose for their 8gpm machines and love it, says everything is better in many ways.

Not a problem, it was taken from gereralpump.com. I hope that others see this as well, they are wasting a lot of energy and may not get the desired cleaning units at their gun's tip.

Hey Chris, the only disadvantage of 1/2" hose is, your arms, back, and leg, feel soar from pulling it all night :) .

After coming across this hose friction loss chart above (http://www.propowerwash.com/board/upload/showpost.php?p=136786&postcount=22), talking with Jim at crystal cleaning company, and the fact I new that I wanted to run 200ft of hose at a pump head max pressure of only 3600psi (TSF2021) the choice was logical 1/2" hose was the way to go.

Guys dont forget to calculate the losses in the coil too, assume the same as hoses.

After designing my system there are two major things I should have done different, increase horse power on the motor and used a 3/4" coil. After talking with Travis at Farleys Coil, 3/4" is the way to go on 8.5 gpm, he actually suggested anything over 7gpm, while the builder suggested anything over 9 gpm use a 3/4" coil. These options may have "bust" my budget. but long term it may have proved to be beneficial.

Nigel, You are sooooo right about this. we have been using 1/2 inch hoses sine 1993 ish. We have notice that the flow is easier on the pumps. For example, we was rebuilding our pumps every 3 years or so with the 3/8 hose at 200 ft. When we went to 1/2 inch line, we have not replaced or had any problems with the pumps. NOTHING for 10+ years.

I have been telling everyone here about the 1/2 inch and the benefits of having a 1/2 inch based on my experience, though I have not had the time to get the information in writing.

We just bought (4) 200 ft of R2 hose. My discounted price was $2,000. That was a great deal. Bought from Precision in LA, California. Quotes out here was going for 3k. NOTE that our hose is a high end hose. Most will not need this type of hose, and so the price will be allot less.

As far as coils, ANYTHING bigger than 1/2 is better if you are doing long runs and have over 5.4 GPM's. we have 3/4. went from 1/2. WHAT A DIFFERENCE !!! Mountain bike vs a Harley type of difference.

Nigel, Good to talk with you about this stuff last night and Days past.

Oh, and thanks for keeping me AWAKE yesterday while driving. I am getting tooooooo old to work 18 hours and then get only 3 hours of rest before going out for another 16 hours again. And I will not schedule a garage the week taxes are due. Just not going to happen !!!

Actually, I am late ..... I overslept today. That’s the good thing about being the boss…. You can do that once in awhile and blame it on the client or office work. HA HA HA. Got to go. Hopefully we will be 2/3 done today.

Jim
 
Imagine what it would be if you actually were running a gun!
BTW, just so you know, I cleaned about 60,000 sq.ft. of concrete yesterday, and washed 150 vehicles, by myself, for most of it, before the day was done, but, it was only a 17 hour day.
