The HydroCAD offices will be closed on Monday, September 2nd to observe the Labor Day holiday. We will reopen at 9:00 AM Eastern on Tuesday, September 3rd. Have a safe and happy weekend!

UPDATE: The issue with our shopping cart has been resolved, and as of today-- June 28th-- our online store is back to being fully operational, so you can place your orders now! Apologies for any inconvenience our cart being down may have caused yesterday.

If you experience any trouble today with our online shopping cart, please know that we are aware of the issue and are working to resolve it. We are happy to take your order by phone. During regular business hours just dial "0" to bypass the auto-attendant and get a real person!
