Joey came by today to check on our fire place because we were concerned about a gas leak. From the start, this experience was great. It was easy to submit a booking request and the scheduler called a few hours afterward to set the time. They had an appointment available the very same day, which was great. I love how they sent info ahead regarding who the tech was. Joey called me before hand to say he could come by sooner if we wanted. He was professional, straight to the point, and put our minds at ease. I will definitely give these guys a call for any future plumbing issues we run into.Posted on David LinnTrustindex verifies that the original source of the review is Google.

He rocked!Posted on Richard HouseTrustindex verifies that the original source of the review is Google. Outstanding service in every way.

Install a recirculating pump. Joey did outstanding work. Good price. Only problem is Plumsmart management sent Jorge the day before for the quote. They replaced Jorge with Joey which I am ok with. Just needed to be notified of the change. After the service was completed they sent me a review on Jorge, not Joey who did the work. No recipe either for work perform.Posted on Mary RamirezTrustindex verifies that the original source of the review is Google. Joey was very helpful and kind, he took the time to explain, was very professional. Thank you for your good service, and appreciate the discount on first time use, really came in handy. Thank you.

FAQs
What causes main water line leaks in San Antonio?
Soil shifting, age, corrosion, and temperature swings can stress underground pipes. In San Antonio, dry spells and heavy rains can move soil around the line. Small cracks can turn into bigger breaks if left alone, so early repair and testing matter.
How do I know my main water line is leaking?
Common clues include a sudden high water bill, lower water pressure in the whole house, wet areas in the yard, or a water meter that keeps spinning when all faucets are off. If you are unsure, we can confirm it with proper equipment.
Can you repair my water line without digging up?
Sometimes, yes. If the pipe and location allow, PlumbSmart may use less invasive methods like spot repairs, pipe lining, or targeted digging instead of trenching the whole yard. We inspect first, explain the pros and cons, and aim to protect your landscaping.
How long does main water line repair usually take?
Many repairs can be completed the same day once we locate the problem, but timing depends on depth, pipe type, and how bad the damage is. After inspection, we give you a clear plan, material needs, and a realistic schedule.
Do I need to shut off water for the repair?
Most main water line repairs require a temporary water shutoff for safety. We will tell you ahead of time, keep the downtime as short as possible, and make sure water is restored and tested before we leave your San Antonio home.

PlumbSmart — San Antonio
You can call us for assistance 24 hours, 7 days a week.
San Antonio is a growing city with long hot summers, shifting soils, and the occasional hard freeze. Those conditions can be rough on buried pipes and connections. Older homes may also have aging water lines that are ready to fail. When a main water line starts leaking or breaks, you may notice low pressure, discolored water, wet spots in the yard, or water pooling near the street.
PlumbSmart is local to San Antonio, and we know the neighborhoods and the common water line problems homes face. From small leaks to major breaks, our plumbers help you restore water service quickly and safely.
Main water line repair is not just about stopping the leak. It is about protecting your foundation, landscaping, and water quality. We can recommend the right fix, such as spot repair, pipe lining, or replacement, so you get a long lasting solution and fewer surprises.
There is more to your plumbing than fixing problems after they happen. Regular water line inspections and maintenance can catch small issues before they become expensive emergencies. During a visit, we can check water pressure, evaluate shutoff valves, look for hidden leaks, review pipe condition based on your home’s age and materials, and suggest upgrades. We can also help you prepare for seasonal temperature swings and reduce wasted water overall.
