Frequently Asked Questions

What is the PSI of the pump?

The HD5000 sprayer has a variable pressure adjuster that can adjust pressure between 30 and 65 PSI.

Can I leave my solution in the canister when not in use?

We do not recommend letting solution sit in the canister when not in use, as it could lead to the unit getting clogged.

Are there any cleaning instructions to follow after each use?

Consistent with all our products, we recommend that you rinse the unit out with clean water after each use. After every couple uses, let a full tank of warm water sit for a couple of hours and then spray it all out to ensure longevity of your product.

Are the numbers on the tank quarts or liters?

There's liter and gallon markings on the tank.

What is the return policy?

We offer a 45 day money back guarantee as well as a 1 year warranty.
