Does your Pool need a repair in the middle of the summer

The worst case scenario for all pool owners in the summer:

The pool needs an urgent repair!

Leaking skimmers are often the reason for a water loos in a pool and  is big problem for any pool, since this can lead to a structural damage.
Lowering the water level to do a repair in dry conditions cost a lot of water and chemicals.

Loose or broken tiles are the main reason for cut feet in swimming pools,  but emptying the whole pool in the middle of the summer is not an option but needs to be done, in conventional repairs, to prevent swimmers injuries.

Screws of drain covers, lights or ladders are getting lose and it is impossible to get them tightened.

Pool vinyl of above ground pools got damaged from pet’s ,lawn mowers etc. or the bottom seal got loose over time.

There are many reasons for pool repairs when the summer is in full swing and the pool can’t be emptied for commercial reasons,  family peace and / or it is simply too expensive.

There are even countries where you have to apply for a permission to empty and fill a pool from the government and that takes time or get denied for reasons like drought, disposal of the water issues etc.

A repair underwater is the only solution to save the summer, but is there a way that underwater repairs in swimming pools last?
Due to the pool chemicals attacking the repair all the time even in a saltwater pools or with one of the new sanitising systems where it seems no one has experience if a repair would last.

Cost efficacy tip number 1 for your swimming pool

Many people which have bought a house with a swimming pool for the first time are shocked about their electricity bill.

Before accusing the kids or partner wasting energy have a look at your pool pump system. Many houses with pool have their pump

since the time the pool was build. When looking at the pump  it is like looking at an old sometimes almost historical refrigerator which

would have been replaced directly when moving into the house. Often replacing the pump to a nowadays low energy consumption pump will save you a lot of money,

is far more environmentally friendly and  maintains family peace. There are many different models on the market and looking at a solar powered model and/ or a

combination of  pump and heating system could also extant your pool summer.

Storm at the pool

After a bad storm a pool needs special care, if you have no fundamental experience how to do it, it is the time to get a pool pro in, to show you what need to be done and how it need to be done.

To do each step at the right time is essential and it would be trying to save money at the wrong end without expert advice.

You can do a lot of harm to the structure and armatures and at the end your pools is still unbalanced, cloudy and or full of algae.

What is the advantage to repair a pool underwater?

It is pretty obvious that an empty pool is a dangerous whole in the ground and a massive loss of income for a commercial pool owner.

You are having a hotel and you have to announce that your pool is closed for repairs for 2 weeks or longer, you don’t know when to schedule it to minimize the loss of income.

It is very lightly that guests will not book your hotel for the time the pool is empty and spent their holydays in another hotel nearby where the pool is ready to jump in.

The worst case scenario is that these guests are never coming back to your hotel ever because they liked the hotel of your competition.

What can be done to prevent emptying the pool when tiles are loose, expansion joint needs to be fixed or replaced or the pool is losing water because the skimmers are leaking etc…

The answer is very easy , the repair can be done directly underwater with Underwater Magic adhesive and sealant, the only proven product which adheres underwater and lasts for years to come.

Are you ready to open up your in-ground pool by yourself this year?

First remove all water, leaves, and debris from your cover.

As soon as the water is off the cover, you can use a broom to sweep off any debris. Never use anything sharp or harsh on your cover.

You can also wait a day or two for the cover to dry and blow the debris off with a leaf blower, this is a very gently way to get it done.

Remove the cover without getting any debris, into the pool which may been left on the cover.

If dirty water or debris fall in the water, it’s not a big deal, you just have to remove it from the water later.

Lay the cover out on your lawn or a nearby area. Use water, soap, and a soft brush to wash your cover carefully.

You can also use cover washing liquid. Remove all the winter plugs from the openings in your pool, including return jets and step jets.

Than replace your return lines with proper eyeball or jet fittings.

Remove the ice compensator(s) from your skimmer bucket(s) (Gizmo) as well as  the winter plugs from the bottom. Then, replace the skimmer baskets

if needed. Now you are ready to re-Install your deck Equipment after inspecting of it got damaged in the winter storage, remember to lubricate all bolts  rusting throughout the summer months

can be prevented during the summer. Your pool might have lost or drained water during winterization. . If the water level in your pool is below the midway point of the skimmer opening, fill it up with your garden hose.

Replace the drain plugs and other parts, including your pressure gauge, on your filter and pump. Your filter should have one major drain plug and your pump may have one or two.

If you have a multiport valve, make sure you replace the air bleeder, sight glass, and pressure gauge. Remember to turn the multiport valve handle to “Filter.”

Check the lid o-ring on the pump housing. Bend it with your fingers to check for cracks in the rubber. A defective o-ring will cause a filter to pull air, which is not good at all. If this is the case, you should replace it. If the o-ring looks good, I suggest applying a Teflon-based o-ring lubricant (I recommend using Magic Lube) to create a good seal and making it easy to remove the pump lid when needed.

Re-install the additional equipment, including a booster pump, heater and or the chlorine dispenser and make sure all drain plugs are securely in place.

Turn on the power to your pump and filter. Make sure the system starts up properly. Check for any leaks or drips.

If your pump is not pulling the water, you’ll need to help to prime the pump. Shut off the filter system, remove the pump lid and then fill the housing with water. Use a garden hose or a bucket of pool water for this.

Replace the lid and turn the filter back on. This usually helps the pump to pull water in from the skimmers) and main drains.

Backwash your sand filter if the pressure is over 15 psi. Now clean up the pool from all leafs etc. Turn on the valves to pull water in from the bottom drains. This helps the filter to get the dirt and debris of the floor of the pool.

Important: Take a sample of the pool water to a l pool supply store and get it professionally analyzed. Then you follow their instructions to get your pool back into balance. Take a second sample to the shop following their advice to make sure it is well balanced now.

How many hours need a pool pump to run?

In some parts of the world, pool owners can keep their pools open all year around.

In such an area, you can run your pump less during the colder months 4 to 6 hours a day.

When it’s hot outside, pump and filter need to run for 8 to 12 hours a day especially if you use the pool a lot.

You need to keep that water clean and balanced as well as moving and moving, so don’t run into any problems, such as an algae growth or cloudy water, just to save a few pennies.

The water change and chemicals to get your pool back in balance cost more, trust me.

Balanced pools last longer cost less and they are more fun !
