Reliable Santa Clara Water Heater Repair & Installation

Think Your Water Heater Could Make Use of an Extra Hand?

Water heating systems are no longer seen as a luxury by those residing in Bay Area, Santa Clara — in fact, water heaters have emerged as a necessity in recent times to heat water to a certain temperature to be able to enjoy a nice, hot bath whenever desired. Smart Plumber offers water heater installation and repair services to ensure the procedure is carried out correctly.

If you observe fluctuations in temperature, water leakage, lowered hot water pressure, gurgling sounds, rusty water, or unpleasant smells, it’s time to consult a plumber regarding the repair or replacement of your water heater.

Hot water is a continuous effort for your water heaters. Like with all machines, there comes the point when they too may need some plumbing services. The lack of scheduled maintenance on your part may result in a lack of hot water. Trust your local plumbers: you do not want this coming to light while standing under your cooling shower jets.

Instead of dealing with a cold day in hell, get your water heater looked at from time to time. If it stops working suddenly, call in your Smart Plumbers for an inspection. Our local plumbers will not be deterred, whether it’s a tank or tankless heater. They have the skills and expertise required to not only install gas, tankless, and electric heaters but repair and replace them as well.

Plumbers and homeowners probably know that water heaters have a certain time limit. Even with the best care and maintenance, a ten-year-old water heater may start showing signs of wear through increasingly diminished performance. This might happen slowly, so you may not notice the cooling water right away.

However, once you notice a problem with your water heater, get the local plumber on the case right away. The plumbing services at Smart Plumbers are diverse and offered by experienced plumbers who know exactly what they’re doing. Have them secure the gas line, install a new water heater, or provide their plumbing services for routine inspection or repair.

Avoid the dangers of an incorrectly installed water heater by hiring local plumbers who put great stock in safety and quality of service.

Water Heater Cleaning

It’s advisable to clean the water heater at least once a year to prevent sediment build-up. Otherwise, minerals will make it difficult for the burner to heat the water, worse, potentially clog the pipes. Spring is the best season to clean the water heater.

Though you may have drained all of the water, lots of sediment should remain in the tank. Then you need to reconnect the water line and open the shut-off valve of the water heater. The water will drop from the top of the tank to the bottom of it. The force of the dropping water should make the sediment rise from the bottom, making it flow out of the drain valve.

Even after the above process, not all of the sediment will come out of the tank, but it should help take more sediment.

If your drain valve is plastic and old, there is a possibility of leaking after shutting the drain valve off. If so, you have to replace the drain valve.

No Hot Water

When there is no hot water, please check the burner and pilot. If there is no fire on the pilot, you need to change the thermal coupler. It usually is worn out after 3~4 years.

Combustion Air Requirment

Ordinarily, many people are installing the water heater at the garage. But sometimes, you need to install it inside of the house. If you have to install it inside the house, you have to consider sufficient fresh air.

Code requires two cubic feet of o2 to one cubic foot of the gas. So, for example, if the capacity of a gas water heater is 50,000BTU, need 2,500 cu ft of fresh air.

As you see in the picture, Code is requiring two of 100 sq. In. Net opening space for 40.000 BTU water heater.

Also, these open spaces should be within 12” from the top and the bottom.

So if you install 40 gallons gas water heater in a confined space, you need at least two of 125 sq. In. Net open space within 12” at the top and the bottom.

T&P Valve

A temperature and pressure relief valve (T&P valve) is required on all water heaters.

When the temperature is exceeded 210° F, the T&P valve will be opened and release the hot water to control the inside temperature.

However, this valve is consumable, and it would leak after 3~4 years.

If it is leaking, water will come out through the T&P valve drain pipe.

When it is leaking, you need to change it.

Water Heater Installation

Disconnect inlet and outlet pipe and draining all water in the tank with an opening drain valve at the lower side of the water heater.

take off the old straps.

Shut the gas valve off and disconnect the gas line. Now you can remove the old water heater.

Install new straps and 2″ thick wood space bar. (water heater needs 2″ gap from the wall) and set up the new water heater.

Connecting hot and cold water lines with the flexible water lines, you need to install a valve at the cold water line side and join the vent pipe. Also, you need to tighten 2 of the straps.
