How to drain a swimming pool

Swimming pools are so much fun in the hot summer months, but the maintenance can be tricky if you aren’t a professional. Draining your pool in particular can seem like a difficult task. While some steps can vary depending on what type of pool you have, most of these steps will hold true for any type of pool. No matter why you’re draining your pool, here are the basics!

How to drain the water from your pool

The first thing you should consider is consulting an expert. This can be helpful in determining whether or not you actually need to drain your pool and can help you prepare for the undertaking. If you’re draining your pool to do repairs, you should almost certainly talk to a professional to see if the damage you’re repairing will impact the draining process. It’s also important to make sure you have all the supplies you’ll need before you get started.

Once your pool is drained, you’ll want to clean or repair it and then refill it quickly to prevent any problems. Before you start draining your pool, check that there are no chemicals left in the water. Your water should be as neutral as possible to avoid any chemical waste making its way into your yard. You also want to consider the weather. A sunny day with temperatures of under 80 degrees Fahrenheit is ideal. If you have an inground swimming pool, avoid draining your pool following heavy rains, as rain makes the ground softer, which can lead to your pool popping out of the ground.

The first step to draining your pool is to turn off any pool equipment you have in place. This includes things like underwater lights and your pump. Underwater pool equipment is kept cool through the water, so once the pool is drained, it can easily overheat if left on. Although your pool pump can be used to drain part of your pool, once the water level gets too low, the pump will begin taking on air instead of water, which damages the pump. Instead, use a submersible pump. Make sure the pump’s power cord is long enough to reach out of the pool, securely attach your drainage hose, and place the pump in the deep end of your pool.

If your pool is an inground pool, then once it’s almost entirely drained, you’ll need to open the hydrostatic pressure relief valve. That sounds technical and unpleasant, but it’s honestly not that bad. The valves are the small white circles embedded in the bottom of your pool. They’re there to relieve pressure created by groundwater. When your pool is full, the weight of the pool water counteracts the groundwater, but once the pool water is drained, the groundwater no longer has anything holding it down, and pressure starts to build. If your valves stay closed, the pressure can damage your pool or even cause it to pop out of the ground.

Depending on the lining of your pool, you may have a cover that needs to be removed first. Valve removal tools can be bought at most pool supply stores, but large pliers will also work. Twist the valve out of its socket and set it somewhere safely out of the way. Unless your valve is old or damaged, you can reuse this valve when you’re ready to refill your pool.

Where should the runoff go?

Your runoff should not go into your yard. The sudden influx of water and potential chemicals can cause a lot of damage to the ground. Instead, drain your pool into the nearest sewer clean-out. The ideal clean-out is downhill from your pool so that the pump doesn’t need to work as hard, but if the only available clean-outs are uphill, it isn’t impossible to drain into them — it may just take a bit longer. Some cities allow for water to be drained into the street or storm drains, but others do not. Check with your local authorities to see what the regulations are in your area.

Do you need to get approval to drain your pool?

This is another thing that you’ll need to check with your local authorities about first. Some areas don’t need any approval, as long as you’re disposing of your water properly. Others do require approval, and improper draining can lead to hefty fines.

Swimming pool maintenance can seem technical and overwhelming, but ultimately, it doesn’t have to be. By following the steps carefully, consulting with an expert as necessary, and using your best judgment, you can be self-sufficient. Now that you know how to drain your swimming pool, you can experience the satisfaction that comes with doing it yourself.

How to install an above-ground pool liner safely
Woman in pool

Having a pool at home is one of the best things during hot summers. The kids can spend hours playing outside and getting all their energy out, and you can relax on a floatie with an ice-cold drink. However, pool maintenance isn't so glamorous, and it can be intimidating to take on a task such as replacing the pool liner. Below, we talk about what you need to know about pool liners, what to consider when buying one, how to install it, and what elements to watch out for to keep your liner healthy.

Why you need an above-ground liner
Pool liners for above-ground pools are essential. The pool wouldn't be able to hold water if it didn't have one. Pool liners also help maintain the pool's structural integrity. Above-ground pools don't have the earth around their sides to help support them that in-ground pools do. That's why having a sturdy and properly installed liner is critical to your above-ground pool's health and longevity. Liners also ensure the pool doesn't leak.
What to consider when buying
There are three types of pool liners to choose from, and often which one is best for you will be determined by the kind of pool you have and the aesthetic you're going for. The first type is called an overlap liner. These are easy to install and are pretty affordable. They fit almost all above-ground pools as well and come in a decent range of patterns and colors. The second type is beaded liners. These are the easiest of the three to replace, and they're also the easiest to find in stores. Lastly, unibeaded liners are more of an investment and can be more challenging for novice pool owners to install. Be sure you find a liner that fits with your pool's needs, your experience level, and suits the aesthetic you're going for.
How to install an above ground liner
It's best to take on the task of installing a new liner with a friend. Two sets of hands will make the process much easier and will make it much less likely that you end up with a crooked liner or having to start over.

Everything you should consider before painting your pool
painting a pool

Some tasks can be quickly taken on in an afternoon, while others weigh on your shoulders. Sometimes this weight is because of the size of the project, while other times, it's because you're not sure what to do. Today we're going to help you tackle a project you might be putting off. We'll talk about why you might want to paint your pool, what you should consider before starting, and how to get started.
Why you might need to paint your pool
One of the main reasons pool owners want to paint their pool is that the original paint is no longer viable. It might be chipping, or the color has faded to an ugly sunburnt shade. Another reason might be simply because of aesthetics. Perhaps your style has changed, or it's a new home and you don't like the style the last homeowners chose. Either way, it's time to repaint the pool. Lastly, you might need to repaint your pool because the integrity of the pool requires repair, so you'll need to patch the paint anyway.

What to consider before painting your pool
Before jumping right in, there are a few things you should consider before repainting your pool. This is a big project, and to set yourself up for success, you'll want to have everything planned out to ensure it runs as smoothly as it can.
Time of year
If you want to repaint your pool, but you're about to head into the rainy season, you might want to reconsider. A pool will need to stay dry and clear of debris for a long while during the painting process, and if there's a chance you might get rain, you'll want to reschedule.
What color to paint
This might seem elementary, but choosing your color way ahead of time can alleviate any anxiety you have about choosing the right color. If you wait until the day before to decide which shade of blue you're going with, you might not have time to think about it and end up regretting it. The last thing you want to do after painting your pool is to have to repaint it.
Gathering supplies
Nothing slows a project down like a run to the hardware store. Check and recheck your list of supplies and be extra sure that you have everything you need. You might even want to buy double of some things to ensure you have what you need when you need it. If you save the receipts, you'll likely be able to return it if you don't use it. Better to be safe than sorry.
Clean, clean, clean
For the best results, you'll want that pool as clean as you can get it. So while it might be tempting to rush through the cleaning steps, we strongly urge you to resist and deep clean your pool before painting it.
Protective gear
Luckily, painting a pool often means you'll be outside, so the fumes of the paint won't be as big of an issue as they are when inside. However, getting pool paint all over your clothes and skin and possibly your eyes isn't ideal. Be sure to wear protective clothing and maybe even safety glasses to protect your eyes. There are many chemicals in paint, and it's best to avoid them as much as possible.
