We gush over technological advances to our shiny Sub-Zeros and glitzy Viking ranges, but when was the last time you heard someone rave about the modern features found in their new water heater. Water heaters are often taken for granted and don’t possess the “Bling Factor” of other home appliances but their attributes are attractive in their own way.

These Duplex strainers use 3-way balls as diverter valves. This design with its PTFE seats provides bubble-tight shut-off, eliminating the costly and potentially dangerous leakage into the chamber not in use. The two part body casting allows true-inline maintainability. All parts of the valve are accessible after removing the basket chamber without removing the strainer from the line. A gear operator is standard on the 4" & 6" units, allowing for a very easy change over. On models with a handle, the chamber in use is covered by the handle preventing accidental opening of the pressurized chamber and allowing easy access to the side to be serviced. The large open area ratio of the basket assures a minimum pressure drop across the unit. Perforated stainless steel (304) baskets are standard on all models, with mesh lining optional.

Water heaters can start to shake just like your clothes steam and moisture produced is greater than normal. The steam increases the pressure inside your water heater causing it to become unstable. Water heaters can start to shake just like your clothes washer does when it’s overloaded or unbalanced. This is where the TPR Valve comes into play. When something goes wrong, the valve automatically opens to release excess pressure through a discharge line.

If your water heater doesn’t have a TPR valve or if the TPR valve ceases to function properly, your water heater can literally blow up and put the safety of your family and home at risk.
