    If pressure and flow are good at the house, but suck at the kennel. Then its line losses between house and kennel. Upsize pipe.

    If pressure and flow are just ok at house, and suck at kennel, I'd back my tap up to the meter and upsize pipe starting there.

    The meter will always be your choke point, its all about loosing as little pressure from there to the destination.

    10GPM in a 3/4" PEX results in a loss of +/-13PSI per hundred foot of pipe. 10GPM in a 1" PEX results in a loss of +/-3.5PSI per hundred foot of pipe.

    Maybe I should just dig a well.

    These are some friction pressure loss charts I found.

    I don't doubt any of that info, however if it's being fed with a 3/4" pipe upsizing downstream will not gain you anything. The "loss" is already there in the supplying pipe.

    It’s not about gaining anything. It’s about reducing the amount of loss over the distance from the point of connection to the kennel. I guarantee his water pressure is better at the meter than at his kennel. We are simply trying to reduce the amount of pressure loss over that distance.

    It comes down to reducing friction. Which can be accomplished by either shortening the run or increasing the pipe size.

    I think what's being said here is a hose nozzle will make it spray harder.


    Correct....I was agreeing with your questioning of increase in pressure. Quick response this AM wasn't as thorough as it needed to be...pressure being a function of drag, velocity being the perceived increase in pressure.

    Set up a water storage tank at the kennel that can be filled with the pex line, make sure the tank holds enough water for intended purpose- connect a proper sized Jabsco pump to the outlet of the tank and hang onto your hose.

    Part of what we do is pressure washing docks, some of them are 1000' long. I keep 1200' of the large commercial grade water hose on hand for this work. Most of the long docks require the water tank with outlet pump to prevent burning up the pressure washer.

    No sir, they are pretty flush.

    Run as big of a pipe as you can to the kennel (a tank at the kennel is nothing more than a giant ass, albeit short, pipe) then use the biggest hose and smallest nozzle you have available to spray the shit out of your kennel.

    If you want to talk about laminar boundary layers then we can, but the above is all you really need to know.

    I don't think that chart applies because there's no increase or decrease in elevation.

    I think you are misguided.

    That’s a pressure-velocity diagram. The height function is entirely contained in the pressure (y) axis and the man wanting to spray the shit out of his kennels has already said there’s no height factor at play in his shit spraying evolution.

    Put your thumb over the end of the hose pipe. Viola, increase in pressure.

    Not pipe size, outlet.

    You’re wrong. Putting your thumb over the end increases velocity…….

    I believe you but the way I read it the pressure drop is 0 foot of head per 100 feet of pipe to the curve is actually just the bottom line, ie the x-axis, right? If so, the pressure drop is read off of the right-hand vertical axis scale and is 0? What am I missing?

    Are the dogs in the kennel force fetched?

    Yes, at zero flow there is zero drop in pressure over 100’ of pipe. And that’s only at 0/0, or origin, of the graph.

    The bigger the pipe the higher velocity you can have without a significant loss in pressure. This is a function of not wiping away the laminar boundary layer and causing turbulent flow. The graph of the pressure drop could be expressed as the rate of change of the Reynolds number as velocity increases if you really want to get down in the ditches on this, lol.
