Why HydroClaw?
You have better things to do than spend time installing an expansion tank. HydroClaw makes it safe, fast, and professional.
Save Time on Every Install
You have better things to do than spend time wrestling with expansion tank mounting. HydroClaw's clamp-and-bolt design gets your tank securely mounted in minutes, not hours.
Eliminate Safety Risk
A waterlogged #60 expansion tank can weigh 72 lbs. That's like hanging a bowling ball from your piping. HydroClaw transfers all that weight to the structure where it belongs.
Professional Appearance
Clean, organized mechanical rooms reflect your quality of work. HydroClaw gives every install that professional, engineered look that sets your work apart.
Contractor-Friendly Design
No special training, no specialty tools. HydroClaw is designed by contractors who understand what works on the job — because they've been there.
