How Does Plumbing Work?

Last time on the blog we dialed it back and talked about the basic plumber services available here at Economy Plumbing Service LLC. This time we’re going to stick in that angle of bigger picture discussion and answer a question many might have but feel a bit silly to ask: just how does plumbing work? Curious? Read more, we’ll give you a basic rundown of this wonderful system.

How Does Plumbing Work

Plumbing works on a few different laws of nature. Gravity, pressure, the natural movement of water. It leverages those forces to direct the water where we want it to go. Let’s simplify it even further.

Think of a giant hose. This is your city’s utility lines. The hose is turned on and water flows out the end. But lets say the end of it is blocked, like a spray nozzle is added to the hose. The water stops flowing but the hose stays full right? That’s because of water pressure. Now imagine a hundred small hoses all with faucets, all running from that giant hose. These are the plumbing systems in your neighborhood. With the water to the giant hose still turned on, those small hoses all fill up and are ready to be used! You open the faucet of the smaller hose and water comes out, pushed out from the small hose which is pushed out from the giant hose.

That’s all because of pressure. That pressure is built sometimes by gravity, by having water towers higher up, the water wants to shoot down, creating that pressure down the pipes and lines. Of course, pumps can also be used to move water where gravity and pressure alone don’t do that job.

The Two Plumbing Subsystems

Plumbing is made up of two different water systems. One to bring freshwater in, the other to take away wastewater.  The pressure we talked about is only present in the freshwater system. That’s what allows clean water to go up through walls, around corners, move upstairs and get wherever else you need it to. When the freshwater is used it then enters the drainage systems.

Drainage systems do not depend on the pressure as the freshwater (or supply) system does. Instead, wastewater leaves your home through drainage pipes that are angled downward, allowing gravity to get to work and pull the water (and waste) down with it! There are a few more pieces involved in drain lines to make sure everything works like it out to including traps, vents, and cleanouts. They help the wastewater flow correctly, as well as create seals with water to prevent gas or smells from developing.

Let’s lay it all out in a sort of step by step process.

  1. Water comes through the city utility supply lines via pressure.
  2. The water moves through the supply lines into your home pipes and fixtures.
  3. The water is used, flowing from the fixtures to fill sinks, basins, water heaters, etc.
  4. The used water drains down the sinks and drains into drain lines, running away from your home (thanks gravity!)
  5. The wastewater runs to treatment plants where it is processed and made somewhat usable again.

Where Does Our Clean Water Come From? 

The end of that step by step process might have made you a little scared. ‘The wastewater does what now?’ Don’t worry! Here in Tucson our clean water comes from groundwater, specifically two sources: local precipitation and the Colorado River. That water moves from the Colorado River through the Central Arizona Project canal, some 335 miles from Lake Havasu to just past Tuscon.

Alright, let’s wrap it up here. We hope this little bit has helped you understand how plumbing works.  Luckily for you, if you’re not a plumber you can say ‘Ah forget it!’ and give us experts a call whenever you need the help!

If water goes through it or to it, we do it!

How to Respond Quickly When a Major Pipe Burst Occurs

A major pipe burst can flood your Tucson, AZ home in minutes. Stay calm, act fast, and call an emergency plumber once you've stopped the flow. How to Deal With a Major Pipe Burst, Fast Protect Your Family If you've got small children or pets nearby, get them out of the affected area right away. Either the water itself or an electrical issue could endanger them, and they won't know how to stay out of your way or keep themselves safe. Shut Off the Water Head straight to your home's main shutoff valve: don't worry about assessing the damage or grabbing any belongings yet. Turn the valve clockwise until it stops. In most homes this valve is in the basement near the water heater, by the front foundation wall, or where the main line enters from the street. Turn Off the Electricity If the burst is near any outlets, lights, or appliances, turn off power to those areas at your breaker box. Only do this if you can reach the panel safely without stepping in deep water. If it feels risky, leave it alone and wait for help. Drain Remaining Water from the Pipes With the main water supply off, open all the cold-water faucets in the house and flush the toilets once. This relieves pressure and empties the lines so there's less water to keep spraying from the burst spot. Leave the faucets open until the flow slows to a drip. Document Everything Before Cleanup Get photos and videos of the damage right after you've stopped the water. You'll want evidence of the burst pipe, your wet floors, any affected walls and furniture, and damage to any belongings. You will need this for your insurance claim later, and the insurance companies will need proof that the damage came from this burst pipe rather than something else. Move Belongings and Contain the Water Lift rugs and move electronics, furniture, and important papers out of the wet zone. If the water is spreading, roll up towels or use plastic sheeting to block doorways and keep it from reaching other rooms. Work fast but safely. Don't carry heavy, soaked items if they're too heavy for you, and focus on irreplaceable items first, like photos, electronics, and documents. Call a Tucson, AZ Emergency Plumber Don't wait if water is involved, because every minute you lose is another minute for mold to grow or a new problem to develop.  A good emergency plumber can isolate the problem, make a temporary repair if it's after hours, and plan for a permanent fix as soon as possible while coordinating with a restoration team. Start Removing Standing Water While you wait for the plumber, use mops, towels, a wet/dry vacuum, or buckets to get water off the floor. The faster you remove it, the less it soaks into subfloors or walls. Open the windows and run fans to improve airflow if the weather allows. Your aim is getting the area as dry as possible. You've got this. Act fast, and call us at Economy Plumbing Service, LLC at 520-885-3510 for the best emergency plumbing service in Tucson.

Tankless or Traditional: What’s the Best Water Heater Option for Your Home?

The decision between tankless and traditional models for replacement water heaters in Tucson can make a real difference in your daily comfort and long-term costs. Let's take a closer look at how each type works, which will help you pick the right fit for your household. Traditional Heaters Traditional tank-style water heaters store a set amount of water, usually 40 to 80 gallons, in an insulated tank and keep it hot constantly using either gas or electricity. When you turn on the faucet, hot water flows from the tank while cold water refills it at the bottom. Tankless Heaters These heaters only give you hot water when you need it. Cold water passes through a heat exchanger inside the compact unit, and out comes hot water, nearly instantly. Pros of Both Let's consider the pros of the traditional heaters first: They're cheaper up front Installation is simpler because most homes already have the connections in place When it needs replacing, it's simple and often same-day They can handle a high flow rate (lots of usage simultaneously) The pros list for the tankless heater is also enticing: Less wasted energy from water being heated when it's not needed No running out of water, no matter how many people take showers Longer tank lifespan Takes up less space Cons of Both Here's the downsides to be aware of with traditional heaters: They use more energy (much more, in some cases) They run out of hot water, and you have to wait while they refill They're bulky and need more room for placement They need to be replaced sooner than tankless As for tankless heaters, be aware that: Installation costs are usually higher Initial purchase price is higher Flow rate is lower unless you invest in a bigger (or multiple) units Scale can form inside the heat exchanger faster than in a tank model Best Water Heaters in Tucson: Local Factors There are a few local factors that might also influence your decision. We have hard water, so that means scaling is more of an issue. Both types of heaters need to be flushed to prevent buildup, but the tankless might need it more often. We've also already got high energy bills with the hot summers we have here, so trimming that with a tankless model can make a big difference over time. Tankless water heaters pay for themselves in energy savings in about seven years, and if you take care of your model, it can last up to 20.If you're still weighing the options for your specific setup, give us a call at Economy Plumbing Service LLC here in Tucson at 520-885-3510.

Are Your Gas Lines in Safe? Warning Signs You Can’t Ignore

We rely on our gas lines in Tucson to heat our homes, give us instant hot water, power our stoves, and more. Keeping your gas line safe is a serious responsibility, because the dangers of a problem in the gas line can be deadly. Here's some warning signs to look out for. Warning Signs That Gas Lines in Tucson Are in Trouble Emergency Signs Some warning signs are emergencies, and you cannot ignore them. Call your gas provider or emergency services and leave the area immediately if: You smell a sulfurous odor in or immediately around your house People in the house are suddenly and inexplicably experiencing headaches, dizziness, nausea, or shortness of breath If gas is escaping into the house, it can cause you and your family serious physical harm. The gas, as you breathe it, begins to displace the oxygen in your blood. You gradually asphyxiate or suffocate if you are exposed to too much for too long. Non-Emergency There are other warning signs that are less immediately serious, but you need to pay attention to them, regardless, as they could quickly turn serious: Corrosion Always inspect your pipes regularly, and if you see rust or other corrosion on them, be sure to call a qualified contractor right away. There may also be an issue if you notice flaking or bubbling of paint near your gas lines or a lot of dampness and residue around the fittings. A professional can seal joints and even replace a bad section of pipe if needed. Hissing If you hear hissing near a gas appliance or a meter, it likely means that gas is escaping. Even a little bit of a leak can increase your bills, of course, and indoors, it can create a very dangerous condition. Contact a professional contractor right away to take a look. If it's a single appliance, turn off the gas to that appliance. Bigger Bills If your habits haven't really changed, but the cost of your gas bill keeps going up, try turning off all your gas appliances and writing down the meter reading. Then, wait for an hour or two and check the meter again. If it has gone up, you have a leak. Low Pressure If the flame on your stove or in your furnace doesn't have the power it should have, then you could have a leak somewhere in the line leading to that appliance, or there could be a blockage. There also could be a faulty regulator in the appliance itself or corrosion in the piping. If several appliances seem to be affected, then the issue could be farther down the line and could be either your responsibility or something that your utility company needs to deal with. A contractor can investigate the situation and help you figure out what's going on.
