Backflow-to-building re-pipe completed to meet current code and performance standards

Re-piping work was performed from the backflow preventer to the building to ensure proper water flow, pressure consistency, and compliance with current plumbing codes. This process involved removing outdated or damaged piping and installing new, durable materials designed to improve system longevity and reduce the risk of leaks or contamination. The upgrade enhances overall system efficiency while maintaining safe and reliable water delivery to the building.

Restoring performance and reliability—this pump system is undergoing precision repair to eliminate leaks, improve efficiency, and extend its service life.

Pump system repair involves diagnosing mechanical, hydraulic, or electrical issues that affect performance. Common problems include worn seals, damaged impellers, bearing failures, and clogged lines. The repair process typically begins with a full inspection to identify the root cause of inefficiency or failure.

Routine maintenance and timely repairs not only improve system efficiency but also help conserve energy, maintain consistent flow rates, and extend the overall lifespan of the equipment.

Backflow happens when contaminated water flows back into your clean water supply usually caused by pressure changes or faulty valves. With this backflow it caused cracks in the concrete from the settling of the water and the change in temperature.

Here at Collins Commercial Services we came in and repaired the backflow and certified it. Then we came in and did a full replacement of the cracked concrete to prevent further deterioration.

Running the camera through the line can find problems before they become disasters.

A drain line camera inspection also called sewer scoping involves inserting a waterproof camera attached to a flexible cable into your plumbing system. The camera allows us to see the inside of your pipes in real time.

What we can identify with a camera:
Clogs or blockages
Grease, debris, and even roots
cracks, breaks, or collapsed sections
pipe condition
lost items stuck in the drain

Give us here at Collins Commercial Services so we can ensure your drains are running smooth before any big problem happens.

Today we are looking at a run and start capacitor for a walk in cooler.

Run capacitors keep the compressor and fan motors running efficiently, while start capacitors give them the extra boost needed to start up. Both are critical for keeping your walk in cooler operating smoothly and preventing costly breakdowns.

If a walk in cooler is not starting or struggling to maintain temp the first thing we want to check are the capacitors because that is an inexpensive fix and the most common to fail

Make sure to call Collins Commercial Services so we can make sure that your cooler is working
