What could be a cause of inconsistent hot water temperatures at faucets? (Select 2 answers)

Inadequate balancing of the hot water recirculation system is a primary contributor to inconsistent hot water temperatures at faucets. When a recirculation system is not properly balanced, some areas of the plumbing can receive too much or too little hot water. This results in fluctuating temperatures, as hot water may not reach all fixtures evenly, particularly if the system struggles to maintain flow rates.

Stagnation due to low use or poor design also plays a significant role in the problem of inconsistent hot water temperatures. When hot water sits in pipes unused for prolonged periods, it can cool down, leading to insufficiently heated water at the faucet when a tap is turned on. Moreover, poorly designed plumbing systems may not provide optimal flow paths or may have long dead legs where water stagnates, further contributing to temperature inconsistencies.

Together, these two factors highlight the importance of both system design and operational efficiency in maintaining consistent hot water temperatures throughout a plumbing system.
