Trying to use the pump without a regulator would be a real PITA. You could never shut the spray hose off when the pump was running and as soon as you started the pump the spray hose would start spewing and empty that tank in a hurry. This way you can use an ordinary garden hose and nozzle and let the pump run all you want - water on demand.
PS> You will also have a mobile gun sprayer for Roundup and friends.
