Plumbing FAQs

An active leak, burst pipe, overflowing fixture, sewer or drain backup, no hot water when urgently needed, or a suspected gas issue are commonly treated as urgent. If you are unsure, describe the problem when you call so it can be evaluated.

If water is actively leaking or flooding, shutting off the nearest fixture valve or the main water shutoff, if you know where it is and it is safe to do so, can help limit damage. Avoid using affected fixtures until the problem is evaluated.

Sewer and drain backups can be urgent because of contamination and property risk. Avoid contact with contaminated water, stop using water in the affected area, and call for service so the problem can be evaluated.

Sometimes. In some cases the immediate priority is stabilizing the problem and stopping active damage, with a planned repair to follow. Wills Plumbing & Testing Service explains the recommended next steps when a temporary measure is used.

Leave the area immediately, avoid anything that could create a spark, and once you are safely away, call 911 and contact the gas utility. Address the gas safety concern before calling for plumbing service.

Recurring clogs may be caused by grease, sludge, hair, scale, roots, pipe condition, foreign objects, improper slope, or a deeper sewer line issue. If the same drain keeps clogging or several fixtures are affected, the line may need further evaluation.

A single slow sink, tub, or toilet may be a local fixture clog. Multiple slow drains, gurgling, sewer odors, or wastewater backing up through tubs, showers, or floor drains may point to a main drain or sewer line issue.

Hydro jetting may be recommended when heavy buildup, recurring stoppages, grease, sludge, or certain main-line conditions justify it. It is not automatically needed for every drain clog.

Camera inspection may be recommended when stoppages keep returning, multiple fixtures are affected, roots are suspected, or the pipe condition needs to be verified before recommending repair.

Appropriate equipment and technique matter. Older, damaged, fragile, or collapsed piping may limit what can be safely cleared. Wills Plumbing & Testing Service evaluates the situation and explains when additional inspection or repair may be needed.

No. Avoid chemical drain cleaners before service. Chemical products can create safety concerns for technicians, may damage certain piping materials, and may be forced back out of the line during drain clearing.

Stop using affected fixtures, avoid contact with contaminated water, and call Wills Plumbing & Testing Service. If multiple fixtures are backing up or wastewater is entering the home or building, the issue should be addressed promptly.

Yes. Wills Plumbing & Testing Service handles residential and commercial drain cleaning, depending on service location, technician availability, access, and the type of stoppage.

Wills Plumbing & Testing Service provides professional drain cleaning throughout San Antonio and nearby communities, depending on location and current availability. Contact the office to confirm service availability.

Hydro jetting uses high-pressure water to clean certain drain and sewer lines through a suitable access point. It can help remove grease, sludge, scale, and some types of buildup when line conditions support that approach.

No. Pipe condition, access, the type of stoppage, plumbing age, and risk of damage all have to be evaluated before hydro jetting is recommended.

Depending on the situation, a camera inspection may be recommended before or after hydro jetting to evaluate visible line conditions and possible causes of recurring stoppages.

Hydro jetting can help clear certain root-related blockages, but it does not repair root-damaged, separated, offset, collapsed, or deteriorated pipe. If the line has structural damage, sewer repair or replacement may be needed.

Yes. Hydro jetting may be appropriate for commercial properties, restaurants, food-service facilities, and businesses with recurring drain or sewer buildup when access and pipe conditions support it.

No. Avoid chemical drain cleaners, especially if sewage is backing up or a technician may need to open the line. Chemicals can create safety hazards and complicate service.

Multiple drains backing up at the same time, toilets gurgling, sewage coming up through tubs or showers, sewer odors, or repeated main-line stoppages may indicate a sewer line problem rather than a single fixture clog.

Yes, in some cases. Not every sewer problem requires replacement. Some issues can be cleared or corrected with targeted repair. Replacement should be recommended only when the condition of the line justifies it.

Camera inspection may be recommended when stoppages keep returning, multiple fixtures are affected, roots are suspected, heavy buildup is present, or the condition of the pipe needs to be verified before repair or replacement is recommended.

Repeated backups may be caused by root intrusion, grease buildup, scale, collapsed pipe, old cast iron, improper slope, a pipe belly, damaged cleanouts, or other structural problems in the sewer line.

No. If sewage is backing up into the home or building, stop using water and avoid flushing toilets, running sinks, using showers, doing laundry, or operating dishwashers until the problem is evaluated.

No. Avoid chemical drain cleaners before the technician arrives. They can create safety concerns, damage some piping materials, and may not solve the underlying cause of a recurring sewer stoppage.

Yes. Wills Plumbing & Testing Service evaluates the symptoms, access, line condition, and history of the problem before recommending cleaning, camera inspection, hydro jetting, targeted repair, or replacement when justified.

Warm spots on floors, unexplained water bills, damp flooring, mildew odors, low water pressure, water around exterior walls, or the sound of running water when fixtures are off. These signs do not confirm a slab leak by themselves, but they justify a professional evaluation.

No. Tunneling is only one possible repair approach. The correct method depends on the leak location, pipe condition, access, property layout, safety, code requirements, cost, and long-term practicality.

No. Slab leak and tunneling work depends on diagnosis, access, scope, utility conditions, permitting or inspection needs, crew availability, and the current schedule.

If it is safe, shut off the water supply to reduce damage. Avoid tearing up floors, cutting walls, digging, or attempting pipe repairs yourself. Keep the area clear and document visible damage with photos.

Financing may be available for qualifying larger repair projects, subject to credit approval. See our financing page for current options.

We evaluate leak location, pipe condition, access, safety, code requirements, property layout, disruption, repair cost, and long-term reliability before discussing options with you.

Warning signs may include an unexplained high water bill, water stains, damp flooring, damp walls, mildew odors, low water pressure, the sound of running water when fixtures are off, or recurring leak symptoms.

Wills Plumbing & Testing Service can evaluate hidden leak symptoms and explain the next diagnostic steps. Some leaks can be narrowed down through inspection and testing, while others may require access openings, excavation, tunneling, or specialized repair planning.

No. Leak detection starts with a logical diagnostic process before opening walls, floors, or other materials. However, some leaks may require additional access to confirm the source and complete the repair.

Repair options depend on the leak location, pipe material, access, severity, age of the system, and risk of additional damage. Wills Plumbing & Testing Service explains the practical repair options after diagnosis.

Yes. Even a small leak can damage floors, walls, ceilings, cabinets, and surrounding materials over time. Active leaks should be evaluated promptly to reduce the risk of further damage.

If water is actively leaking, shut off the nearest fixture valve or the main water shutoff if you know where it is and it is safe to do so. Avoid using affected fixtures and keep the area clear.

Leak detection and leak repair are related, but the exact repair scope depends on what is found during diagnosis and what access is required to complete the work properly.

Sometimes. Not every water heater leak means the tank has failed. Some leaks may come from piping connections, valves, drain pans, supply lines, or nearby plumbing. Other leaks may indicate internal tank failure or unsafe conditions where replacement is the safer or more practical option.

No hot water may be caused by different issues depending on whether the water heater is gas or electric. Gas water heaters may involve pilot, burner, gas control, venting, or gas supply concerns. Electric water heaters may involve elements, thermostats, breakers, wiring, or power supply concerns.

Repair may make sense when the issue is isolated to a repairable component, connection, valve, thermostat, element, or other serviceable condition. Replacement may be the better recommendation when the tank has failed, the unit is near the end of its service life, the installation is unsafe, parts are not practical to obtain, or repair costs are not reasonable compared with replacement.

Wills Plumbing & Testing Service evaluates gas and electric water heater problems within the appropriate plumbing service scope. If a problem requires electrical work outside that scope, we can explain the concern and recommend the appropriate next step.

Water around the tank, rust-colored water, age-related deterioration, persistent leaking, unusual noises, or unsafe conditions may indicate a failing tank. The source of the water should be inspected before assuming repair or replacement is the right option.

If the water heater is actively leaking, shut off the water supply to the unit if you know where the valve is and it is safe to do so. Avoid contact with water near electrical components, keep the area clear, and do not attempt gas, electrical, venting, or tank repairs yourself.

Leave the area and call 911 and the gas utility from a safe location. Do not operate switches, appliances, or anything that may create a spark near a suspected gas leak.

Replacement may make sense when the tank has failed, the unit is near the end of its service life, repairs are frequent or costly, the installation is unsafe, or the water heater is undersized. The condition and age of the unit should be evaluated before deciding.

In many cases, yes. A tankless conversion may require changes to gas sizing, venting, electrical, or water connections depending on the existing setup. Wills Plumbing & Testing Service explains what the conversion would involve for your property.

It depends on the type of unit, the existing connections, access, and any code or safety corrections needed. Wills Plumbing & Testing Service can explain what to expect for your specific installation.

The right size depends on hot-water demand, the number of fixtures and occupants, and usage patterns. An undersized unit can struggle to keep up. Wills Plumbing & Testing Service reviews your needs to help match the unit to the property.

No. A tankless option should be recommended only when the property conditions, utility setup, installation requirements, and customer usage needs support that approach.

Some tankless water heater issues can be corrected with maintenance or repair, while others may involve failed components, unsafe installation conditions, age-related deterioration, unavailable parts, utility limitations, or repair costs that make replacement more practical.

Tankless flushing or descaling may help reduce mineral buildup and support proper performance. Maintenance needs vary based on water quality, usage, manufacturer guidance, and equipment condition.

Sometimes. Tankless conversion may require evaluation of gas supply, venting, combustion air, electrical requirements, condensate drainage, access, and other code or safety details before it can be recommended.

Tankless systems heat water on demand, but performance depends on the equipment size, flow demand, incoming water temperature, utility setup, maintenance, and installation conditions. We’ll help set the right expectations for your property.
