New Check Valve Installations Aim to Improve Hot Water Recirculation New installations of check valves on hot water recirculating lines are gaining traction across residential and commercial buildings as contractors look to address common complaints such as lukewarm waits and inconsistent temperature delivery. On recirculating systems, water can sometimes move in the “wrong” direction when pumps cycle or when pressure imbalances occur. A properly selected check valve helps ensure flow moves toward the intended fixtures or loops rather than back toward the source. Why the valve matters on recirculation lines Hot water recirculation is designed to keep water near the desired temperature within distribution pipes. However, without flow-control components, conditions such as differing branch pressures or pump restarts can lead to reverse movement, increasing wait times and wasting water. Check valves act as a one-way barrier. When the system pump p ....
How long does a sump pump last? Lifespan, factors, and maintenance
How long a sump pump lasts depends on several factors, including the type of pump, the environment, and how well it is maintained. The most common residential units fall into two categories: submersible pumps and pedestal pumps. Submersible models are generally designed to operate quietly underwater and tend to last around 8 to 10 years with proper care. Pedestal pumps, which sit above the sump with the motor exposed, may have a shorter lifespan in some setups, often 5 to 7 years, though this can vary based on use and maintenance.
What affects lifespan
Several elements influence how long a sump pump will run before needing replacement:
- Quality and design: Higher-end units with cast iron or bronze components often resist corrosion and wear better than lower-cost plastic models.
- Usage and water conditions: Frequent pumping in heavy rainfall or persistent groundwater increases wear on impellers and ... Read more »
