Christopher 102 Report post Posted January 11, 2009 I have been wondering if the hose reels really restrict the flow because the inlet/outlet on most of the brands are 3/8", 1/2" or 1" so the 3/4" is not common on the major brands. My supply hose reel has the 1/2" inlet/outlet with a reducer bushing on the inlet/outlet for the 3/4" for using 3/4" hose. I am wondering if you should go up to the 1" inlet/oulet for more flow because there are jobs that seem to have good pressure/flow but I am thinking that the hose reel inlet/outlet might be restricting. Do you think it would be worth it to modify/convert a 1/2" hose reel for more flow or buy the larger 1" capacity or is it not worth it? Just trying to figure out how to get more flow to the tank but without the hassle of connecting/disconnecting a jumper to the hose reel (not using the insides and swivel of a hose reel, just using it for storage) and to the tank for each job. I am working on a bid for a chain of stores that would mean between 4-8 per nite if I get the job and do not want the helper forgetting to connect/disconnect the jumper if I decide to go that way. Any help is appreciated. Thanks. _________________ Superior Power Washing Chris Chappell 361-853-2513 House Washing Services in South Texas Exterior House Cleaning in Corpus Christi Texas Share this post Link to post Share on other sites
Christopher 102 Report post Posted January 11, 2009 I am looking at running 200' to 250' of 3/4" supply hose to the tank so I would like to keep the restrictions to a minimum but preferably none. Thanks. _________________ Superior Power Washing Chris Chappell 361-853-2513 Exterior House Cleaning in Corpus Christi Texas Cleaning Concrete Driveways Sidewalks and Walkways in Corpus Christi Texas Share this post Link to post Share on other sites
Joe Ortiz 14 Report post Posted January 12, 2009 fill up a 5gal bucket with the hose alone,then with the hose going through the hose reel and time each one. I dont think it would make much diff. Share this post Link to post Share on other sites
Christopher 102 Report post Posted January 12, 2009 I was going to do that this week along with timing my downstream injectors to see how much they really pull (3 different downstream injectors) on both machines. That would show me how much the hose reel is restricting if at all. Thanks. Share this post Link to post Share on other sites

A 3/4" hose delivers 23 gpm, almost three times what a 1/2" hose delivers. The larger the inside diameter of the hose, the less pressure loss over any distance. If the pressure is low (under 40 psi), the hose is running uphill, or is extra long, then the largest size hose available should be used to minimize pressure loss in the hose line. You will experience pressure loss through the garden hose as you increase the length of hose. The larger the hose ID the less loss you will experience. Any reel regardless of size will create some loss, especially in the swivel. Depending on the size of your water tank you can probably get by. If you have a 500 gallon water tank and fill the tank prior to starting the job you should be able to stay up with the water demand for 8 gpm using 200 ft. of 3/4" garden hose.

Many have no idea of the performance they are losing by using small hose. As you know, the loss of a hose system is the sum of all the parts. Since the manifold of a hose reel, or the swivel, is but a small fraction of the total, we often "get by" with diameters less then what we would like to have. In the OLD Days, it was common knowledge to use as big and short a hose as possible. Somehow, that message got lost. Thanks for bringing the message back!

That is why I do not roll all my hose out. The water does not have to travel so far, keeping your volumn and pressure up. Share this post Link to post Share on other sites

MudDuck 20 Report post Posted January 16, 2009 That is why I do not roll all my hose out. The water does not have to travel so far, keeping your volumn and pressure up. Ditto with Chris,,hose length is hose length,,,100ft is 100ft rolled up or not. Share this post Link to post Share on other sites
Apple Roof Cleaning 202 Report post Posted January 16, 2009 Yes, 100 feet of hose is 100 feet of hose. But coiling hose introduces additional friction losses into the system. All things being equal, a straight hose flows better then one coiled up. Share this post Link to post Share on other sites

It all evens out. But what does make a difference is if you have parked so the hose reel is algned with the longitude of the earth. or is it latitude. Larry will need to step in here now.

Scott Stone 604 Report post Posted January 17, 2009 I have not had a problem with a 3/4" hose, as long as there is adequate water volume from the spigot. That is running to RK-43's off of it full bore. They put out 5.5 gpm, on the machines that I have. Share this post Link to post Share on other sites
Apple Roof Cleaning 202 Report post Posted January 17, 2009 Here is a good explanation of pressure and flow loss. http://osuextra.okstate.edu/pdfs/F-1231web.pdf A coliled hose has a loss of 10 psi. That may be of little importance to someone using a pressure washer, but to a roof cleaner using a 45 psi 12 volt pump, it can matter. Share this post Link to post Share on other sites
