The primary difference is the operating pressure and the target application: hydro jetting is a plumbing tool for clearing and cleaning the inside of pipes at lower pressures, while hydro blasting is a heavy-duty industrial process operating at extreme pressures to strip surfaces, cut through concrete, or clean heavy machinery.
Average cost of hydro jetting
“In California, expect to pay a flat rate of $500 to hydro jet a kitchen or bathroom sink, or $1,000 for a sewer or toilet,” says Rave.
Water jetting is using high velocity water (greater than 100 psi) to clean non-porous surfaces. Hydro blasting is a particular type of high-pressure water jetting to clean items such as exchanger tubes, remove paint or oxidation from surfaces, and other such non-superficial contaminants.
Hydro jetting is highly effective for clearing heavy grease, scale, and stubborn blockages without chemicals, but it is not inherently bad for pipes when applied correctly. It is completely safe for structurally sound pipes (like modern PVC or healthy cast iron), but it can cause severe damage, cracking, or bursting in compromised lines (e.g., old, thin, or already cracked pipes).
Hydroblasting typically uses water pressures ranging from 1,000 to 40,000+ PSI (pounds per square inch). The required pressure depends heavily on the material being removed and the surface being cleaned.
Hydroblasting is not a job you can finish using a garden hose and pressure washer. The high pressure and volume of water required for hydro blasting can only be generated by specialized equipment. This equipment is expensive and requires training to operate safely.
The standard water pressure for a home is 50 to 70 psi. 60 psi is the sweet spot for optimal performance. Keeping it in this range will ensure your plumbing works without damage.
Yes, you can DIY hydro jetting by attaching a specialized sewer jetter hose and nozzle kit to a high-pressure washer, but it requires caution to avoid damaging pipes or injuring yourself. While effective for clearing grease and roots, it is generally recommended to hire a professional, especially for older or clay pipes.
As the fall rains intensify and the seasons shift, one surprising tip is getting renewed attention: pouring vinegar down your drains to help prevent clogs.
PMRs for malignancies of the stomach, kidney, brain, and lymphopoietic system were also elevated, especially among plumbers. Chronic rheumatic heart disease, emphysema, liver cirrhosis, and all external causes of death were the major non-cancer causes with significantly elevated PMRs.
The most effective way to clear a clogged mainline sewer is using a drain auger (sewer snake) or a sewer jetter attached to your outdoor cleanout. For minor sludge or soap blockages, a drain bladder (flush bag) attached to a garden hose can also be used.
Hydro blasting is highly effective for surface preparation and industrial cleaning, but it has significant drawbacks. The primary disadvantages include extreme safety risks (such as high-pressure water injection injuries), high upfront equipment and operational costs, potential surface damage if misused, and complex wastewater management.
As a preventive measure, you should hydro jet your residential sewer line every 1 to 2 years. However, the ideal frequency depends on your specific home, plumbing usage, and the condition of your pipes.
5 Warning Signs Your Pipes Need Hydro Jetting Services
The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
If you're buying a residential gas-powered machine, look for a unit that delivers 2.5 to 2.9 GPM and is rated as close to 3,000 PSI as possible. This will provide very good cleaning and pulling power with a sewer jetter of up to 100 feet in length.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
In particular, avoid using vinegar on natural stone surfaces such as marble, granite, and travertine. The acidity can dull these materials over time and may even break down the sealant that protects them from stains.
Plumbers highly recommend avoiding harsh chemical drain cleaners, as they can corrode pipes and only offer temporary relief. Instead, they suggest preventing buildup through daily habits, using natural enzyme or enzymatic cleaners for maintenance, and letting professional cleaners clear severe blockages.
It's easy with high pressure water jetting equipment rentals from NLB. We have locations across the USA, with the industry's largest fleet of rental units and many of our popular accessories.
For old pipes, the safest drain cleaners are enzymatic cleaners or natural DIY mixtures. These methods dissolve organic blockages safely without the harsh chemical reactions of traditional drain openers, which can easily eat through or corrode aged, brittle plumbing.
Shower water flows down your drain, through a P-trap, and merges with the rest of your home's wastewater. Depending on your location, it travels through sewer lines to a municipal wastewater treatment plant, or to a private underground septic tank in your yard.
Air / gasses in the body would compress significantly, if not allowed to exit the body. Your lungs would collapse in an instant, and your chest cavity would collapse on itself, until all air has escaped, and then replaced by water. Your ear eardrums would also rapture in an instant.
You should expect strong water pressure in your showers and faucets in that range when using properly-sized residential water pumps. Any lower than 40PSI and some shower heads won't operate very well. Any higher than 60PSI -70PSI and you'll have to be careful not to burst any pipes that aren't rated for high pressure.
