Owners call six months after a plant is built: the building is warm, the chiller is new, something is wrong. The chiller is fine. Here is what we find instead.
1. Air in the system
Automatic air vents installed where the drawing showed them instead of at the actual high points. Air collects, pumps cavitate, flow drops. The fix is vents where the air actually goes.
2. Strainers never cleaned
Construction debris in the strainers after flushing. Flow drops at every coil. We clean strainers after flushing and again after the first week of operation.
3. A flush that was a rinse
A real flush runs for hours at velocity with the chemicals the spec calls for. A rinse is a hose. If the balancer could not hit design flows, this is usually why.
4. Hangers that let the pipe sag
Sagging mains trap air and water in the wrong places. Hangers at code spacing for the pipe size, not where the installer could reach.
5. Balancing done before the system was finished
A balance report taken with half the coils isolated is fiction. The balancer should be the last trade in, after flush, treatment and strainer cleaning.
All five are piping-contractor problems, and all five are cheaper to prevent than to find.
Medical gas verification: what to expect and why it fails
The independent verification is the last gate on a medical gas system. Here is what the verifier tests, what fails most often, and how we have kept corrections at zero.
Grease interceptor sizing: why the health inspector and the plumbing inspector disagree
Restaurant owners get caught between two codes. Here is how sizing actually works in East Valley jurisdictions and what to decide before the slab is poured.
Annual backflow testing: what property managers are actually responsible for
Every commercial property has backflow assemblies, every water provider requires annual tests, and most property managers find out when the notice arrives. Here is the routine.
Send the drawings or describe the building.
A project manager or Carol replies the same business day. Contract clients on the 24-hour line get a plumber, not a service.
