Commercial plumbing isn’t an easy task to pull off. Sometimes issues related to commercial plumbing will arise, and you have no choice but to rectify them. Messy and costly to repair, they can erode the trust of residents, customers, or tenants. Here are the 10 typical commercial plumbing issues and how you can fix or avoid them.

Typical commercial plumbing issues - Intro

1. Faucet leaks

Typical commercial plumbing issues - Faucet leaks

A slow-drip leaky faucet may seem trivial, but it can result in thousands of gallons of water waste annually, reflected on your water bill. If left unnoticed, these leaks can cause water to accumulate on floors, inside cabinets, and other hidden areas leading to physical damage and mold growth.

You can schedule weekly checkups for leaks to prevent water waste and increase water bills.

2. Drain clogs

Commercial drains are designed to withstand heavy usage, but frequent abuse by users can cause clogs. Dropping paper towels and other debris into drains can result in blockages if not addressed with due care. Slow draining is a sign of a clog, so it's important to watch out for this sign during use.

You can easily prevent this by inserting drain nests over any drainage entry. If a clog is already happening, you can apply some of the solutions in this article.

3. Toilets keep running

A toilet that runs continuously can lead to significant water waste, reflected in your water bill. While simple toilet parts can be inspected by yourself, the same thing cannot be said about toilets or urinals with automatic flushers. Since it involves an automatic system, it is best to call a professional plumber. These can be complex to diagnose and repair.

4. Broken toilet parts

If you encounter problems with your toilet, turn off the water supply and contact a plumber. If you’re in San Jose, you can give us a call. We’ll be more than happy to assist you.

5. Leaks that are out of sight

Hidden leaks can cause serious wall damage

Leaks can go undetected for an extended period and may only be noticed through a sudden increase in water bills, musty odor, or water damage on walls, ceilings, or floors. Prompt action is crucial to prevent further damage; call a licensed commercial plumber to locate and fix the leak. Ignoring leaks can result in the growth of toxic mold and extensive damage to your property.

6. Low water pressure

This indicates a deeper problem such as a leak or burst pipe. It is important to call a plumber to diagnose the cause of low water pressure and fix it as soon as possible, as this can prevent excessive water waste and associated costs.

7. Stinky sewer

A sewage odor is unpleasant and can signal a pressing plumbing issue that requires immediate attention. At JD Service Now, our technicians are equipped with the necessary tools to locate and resolve blockages or other problems in your main sewer line.

8. Inadequate water temperature

Due to frequent usage, commercial water heaters require more frequent inspections and maintenance compared to residential ones. Regular inspections every few months are necessary to ensure proper functioning. If you experience a lack of hot water or water not reaching the desired temperature, there may be an issue with your water heater.

Typical commercial plumbing issues - Fluctuate water temperature

You can either contact the seller for repair or replace a new one if your heater has been in use for a long time (typically over 10 years).

9. Toilet handles malfunction

Typical commercial plumbing issues - Broken toilet handles

Toilet handles are delicate and not ideal for commercial settings. Frequent usage can break them with ease. Replacing them with motion-activated flushing systems is a better option for buildings with handle toilets. If you prefer to retain the handles, it may be necessary to perform frequent repairs or replacements to maintain proper toilet functionality.

10. Toilet clogs
