How Often Should I Drain Water Heaters?

A water heater is one of those household devices that is very easy to take for granted. It stays out of sight and mind and can still perform its job for years on end without any maintenance at all. You probably only think of it when something goes wrong. However, like most machines, water heaters also require periodic maintenance to maximize energy-efficiency & prolong its lifespan. A forgotten or ignored water heater may keep the hot water flowing for a few years but will slowly cause your utility bills to creep higher & eventually, it will fail altogether.

The best way to protect your water heater is to have your water heater serviced annually by a licensed plumber from Lone Star Water Services. One of our expert plumbers will conduct a full inspection for leaks, rust & other problems, test the valves & thermostat, replace the anode rod to prevent corrosion & flush the tank. Flushing the tank is the one you may want to complete yourself as often as every few months, depending on your local water supply’s mineral content. Learning the process of how to flush a water heater on your own can surely save you a lot of money over a while.

Should I Drain My Water Heater Periodically?

Regularly flushing out lime & other residues in the water heater tank improves the heater’s efficiency & its lifespan. In poorly-maintained water heaters, sediments can gather & calcify, making it challenging to remove. This can become so severe that the complete unit may need to be repaired or replaced. If you flush your tank routinely, you can block sediment & other residues from causing problems.

All sorts of water has some level of mineral content. If you live in an area with a lot of limestone beneath the ground, the groundwater will surely pick up magnesium & calcium deposits, resulting in “hard” water. Hard water forms sediment in the form of limescale that settles & builds up at the bottom of your water heater. With natural gas heaters, this build up of residue can cause uneven heating on the tank that ultimately causes leaks. With electric heaters, this can burn out the lower heating element. And in both gas heaters & electric heaters, sediment buildup can clog the drain valve.

When Should I Flush My Hot Water Heater?

You must flush their water heaters after every 6 months or so, but you should do it more often if you have a hard water supply in your area. Flushing your hot water heater could be needed as often as every few months depending on the local water supply’s mineral content in your locality.

Before You Begin a Water Heater Flush

Before draining the tank, you need to figure out how to turn off your gas water heater. A vacation set might do the trick. Don’t forget to find out whether its pilot light should be lit manually. This information’s best source is the original owner’s manual because pilot lighting procedures vary among models. If you don’t have a manual, check the water heater’s label for a brand name & model number & try to look up the manual online. There must be pilot lighting instructions written on a label on the tank.

How Do I Drain My Tankless Water Heater?

The method specified above refers to conventional tank water heaters. Still, tankless water heaters are also susceptible to damage from mineral sediment. There is an entirely different process to flush tankless water heater equipment & a pump is required to circulate water through the system.

Why is Reverse Osmosis a Great Choice?

After studying this article, we believe that your next step will be deciding to purchase one from Lone Star Water Services (a locally owned and operated water softener & water heater sales & service provider).

Before informing you of some of the advantages, give us the chance to explain what Reverse Osmosis means. Let’s start with the basics, shall we?

What is Reverse Osmosis (RO)?

Reverse Osmosis is the process of deionization or demineralizing water by pushing the water under pressure through a semipermeable membrane.


To embrace Reverse Osmosis, one must understand the process of Osmosis first. It is a process wherein molecules of a solvent pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. In other words, it’s where a weaker saline solution “migrates” to a high saline solution, just as plant roots suck up water from the soil & human kidneys get water from the blood.

If you wonder that a less concentrated solution will have a natural inclination to move to a highly concentrated one, just visualize holding a can full of water with low salt concentration & then holding another can full of water with higher salt concentration.  Now visualize that they are separated by a semipermeable membrane. Because this membrane allows some of the substances to pass through, the water with low salt concentration would then transfer to the can of water with high salt concentration.

Semipermeable membrane

Still, confused? Let us make it simple for you. A semipermeable membrane permits some atoms or molecules to pass through it by diffusion. Take, for example, a screen door. It allows air molecules to pass through it, but insects or anything more significant than the holes can’t pass through.

Let’s have another example—the Gore-Tex synthetic fabric, which contains superfine plastic film. Millions of tiny pores have been cut. These openings are large enough to allow water vapor through but are small enough to block liquid water.

Reverse Osmosis…again

Now, you know what actually is reverse osmosis? That’s right! It’s the osmosis process in reverse! Quite obvious, isn’t it?

However, reversing the naturally occurring Osmosis phenomenon requires energy & the application of that energy to the more concentrated solution. You’re probably aware of an RO system’s components already & you might have come across its RO membrane.

Though this membrane permits water molecules to pass through, it rejects most dissolved bacteria, salts, organics & pyrogens. To perform this, sufficient pressure should be applied to push the water through this RO membrane. This causes the water to get desalinated (demineralized or deionized) in the process, enabling pure water to go through while blocking most of the contaminants.

Now that you understand Osmosis & Reverse Osmosis, you’ll appreciate the following advantages even more!

Perks of Having an RO System

● RO systems remove contaminants.

RO systems can also remove pollutants like pesticides, nitrates, fluoride, bacteria, sulfates, arsenic, pharmaceuticals & more. If your RO system utilizes a carbon filter, it can also eliminate chloramines & chlorine. There is no better way of cleaning water than with an RO system!

● RO systems improve the taste of water.

Thanks to Reverse Osmosis’s powers, contaminants such as salt, particles, colloids & others are removed! Now, you can surely enjoy drinking water that smells great and tastes good too!

● RO systems are easy to maintain

Yup, you’ve read that one right! These water filtration systems have few moving & replaceable parts, doing the cleaning & servicing hassle-free. Plus, if you take care of your RO system the right way, such as following the annual cleaning process & changing out the filters, it can stand the test of time. RO systems, if properly-maintained, last up to 15 years!

● RO systems can save money.

Having an RO system from Lone Star Water Services will also save your money by giving you all the safe, clean water you will ever need. You do not have to buy cases of bottled water because RO filtration provides safe-to-drink water.
