Supply hose diameter and length preference.

[wba123 14]

I am fairly new to this game. I have a 4 gpm, 3750 psi unit. I bought a commercial 3/4 inch diameter supply hose, but it is a pain to store and to move around compared to a 5/8 inch diameter hose.

* Will a 5/8 inch supply hose provide enough water for my unit?

* What diameter and length of supply hose do you use, and why?

Many thanks.

How many feet of supply hose will play a factor in what size you use. If you stuck to 50 feet and had good water sources then the 5/8's will be fine. Do longer hose runs or have a weaker supply line then 3/4's would be better.

I use 5/8 at 125 ft supply line for my 5.6 with no problems

I have 75' of 3/4 and 50' of 5/8...If I can use just the 50', I will...but sometimes, I run them both together. Most homes I've seen are just gushing with water. If they're not that good, invest in a water tank and run your pwasher off that...stick a fitting on the top of the tank to attach your supply hose to so it can act like a buffer...just make sure you keep an eye on the tank.

300+ feet of 3/4 inch hose, and I use all of it all the time.

3/4" for me.

make sure the tank adapter is also what ever your hose is. most feeds are 1/2 and 5/8. i'm not sure why resifential guys would need anything larger than 5/8.

I often get one inch lines but never in anything but industrial.
