I ended up building my own jetter out of a 4000psi pressure washer, bought my tips and hoses through Spartan. And added a booster heater. Got about $700 invested. Trying to figure out how to get more volume through it. It’s fine from Minors. Next project I’m gonna build a trailer sized w/ 250 gallon tank. Any ideas how to increase the gpms. I originally thought booster pump but I’m only picturing that boosting pressure
The only way to get more volume at the same pressure is by using a larger pump with larger passageways. This also means you will either get less pressure for the same price or will have to pay a lot more to match the pressure of the old pump and have more flow.
When you make the passageways larger you increase their surface area exponentially, not linearly. The larger surface area you have the stronger your material must be to have your water at the same pressure. This makes the cost of manufacturing such a pump much more expensive.
Look at a pipe chart and you'll see that a 1" pipe has a much higher pressure rating than a 4" pipe even though the 4" pipe has a bit thicker wall. Remember that PSI stands for pounds per SQUARE INCH.
