In this blog post, we'll explore the possible causes and solutions to this issue.

Understanding Vertical Supply Stacks

A vertical supply stack refers to the network of pipes that supply water to each floor of a building. Over time, these pipes can become clogged, corroded, or damaged, leading to reduced water pressure. If you're experiencing low water pressure on upper floors, it's crucial to assess your vertical supply stack to determine the cause of the problem. Our team can help you inspect your pipes and identify any issues that may be contributing to the low water pressure.

Possible Causes of Low Water Pressure

There are several possible causes of low water pressure on upper floors, including:

  • Clogged or corroded pipes
  • Leaking pipes or fittings
  • Incorrectly sized pipes
  • Malfunctioning water pumps or boosters

If you suspect that your low water pressure is due to a leaking pipe, our team can help you detect and fix the leak. We also offer frozen pipe thawing services to prevent further damage during the winter months.
