The answer to 'what causes hydro jetting' is hydro jetting, also known as hydro-scrubbing or hydro-blasting, is a highly effective plumbing technique used to clear clogged or blocked pipes. This process uses a high-pressure water jet to dislodge and flush out built-up debris, grease, and other obstructions from the interior of pipes.
The powerful water jet, which can reach pressures of up to 4,000 PSI, is able to cut through even the toughest clogs, including tree roots, hardened grease, and mineral deposits. This method is particularly useful for clearing main sewer lines, kitchen drains, and other difficult-to-reach areas where traditional plunging or snaking may not be effective.
