A comparison of swimming pool rollers

April 29th, 2013

If you need a new television or a new car there are so many to choose from it is difficult to decide which is best for you. Fortunately if you need a new swimming pool roller there are not many to choose from so the decision is made a lot easier.

Is it a roller or a reel?

First off all are we using the correct language in calling it a swimming pool roller? Not really. Strictly speaking a roller is used to roll something flat like a rolling pin for cooking or a garden roller for your lawn. We should really call it a reel because it is used  to reel in your cover. But everyone calls it a roller so we will stick with that word.

The component parts of a pool roller.

A pool roller is made up from a long hollow tube that the cover rolls on to. The ends of the hollow tube have and end cap in them to seal them, this is know as the End Boss. The tube is held up by two end stands. The top of end stands look like the letter “Y” and that bit is called the Yoke. The End Boss on the tube fits into the Yoke of the end stand and it rotates in the Yoke. In to the at least one of the End Bosses goes the Steering Wheel, you turn the Steering Wheel to roll up the cover on to the tube. The tube is actually two or three lengths of tube. They overlap each other like a telescope and slide out to the correct width where they are then clamped to each other to fix the width. Between the tube and the cover are a set of webbing straps joining the cover to the tube. When you first turn the wheel the straps pull the cover off the pool and on to the tube.

The straps are fixed to the roller by various means as we will see and the straps fix to the cover usually by the use of male/female plastic poppers and a buckle. The end stand can sit permanently on the side of the pool or it can be on wheels or wheeled castors so you can move the whole roller around. You can un-buckle the straps from the cover and leave the cover on the pool and remove the roller if you wish.

Comparing the Monte Carlo, the Slide Lock and the Economy Reel.

The three main pool rollers on sale in the UK are the known as the Monte Carlo, the Slide Lock and the Economy Reel.

The Economy Reel

The Economy reel is imported in to the UK we believe from the Czech Republic. It has wheels (not castors) on the bottom of one end stand a “T” bar at the other end. It has one Steering Wheel and is suitable for pools up to 15ft wide.  It has two smooth tubes and the straps fix with a self tapping screw. Not the most robust construction but it is a very good roller for small pools.



The Slide Lock Roller is made in the UK. A very popular roller seen on very many pools. It comes with a choice of many types of end stands for floor or wall mounting but the most popular is the free standing version that can have castors fitted. They are made from 1.5 inch stainless steel  with a plain plastic yoke. The tubes are aluminium with two larger ones sliding into a central smaller one. It has groove within it and in the groove is a plastic fitting to take the cover strap. It slides and clamps where you want it. The tubes fix to each other with a small screw.

The Monte Carlo Roller is also made in the UK. Fairly new to the market it has taken over from the Slide Lock as the highest quality roller and is gaining in popularity. The end stands are made from 1.75mm stainless steel. A quarter of an inch might not sound like much but it makes them much more robust than the other two. The yoke is very sturdy and has a roller bearing within it to make rolling smoother. The aluminium tubes are a set of three like the slide lock but they fix together with a clever clamping system inside a groove which is better than the Slide Lock’s system but in the same groove goes the fixing for the cover strap. If you want to move the position of a cover strap you may have to take out a tube clamp, slide the strap fixing past, and then put the tube fixing back on. More fiddly than the slide lock but a more robust system.

Conclusion

For small pools and small budgets choose the Economy Reel. At the top end of the market it is a fight between the Slide Lock and the Monte Carlo. The Monte Carlo is a bit more fiddly to set up but wins out in the end because of its more robust manufacture and its clever design features.

What causes a pool solar cover to break up?

April 26th, 2013

We are often asked why has my swimming pool’s bubble cover started to degrade? The usual pattern is that you find little bits of white plastic floating in your pool water. You wonder where they have come from and eventually find that they are from the underside of your pool cover. The bottom of the bubble has degraded and fallen off.

A typical failure looks something like the image below.

Picture of a failed swimming pool cover

Typical break up of a pool cover

The material becomes brittle and the cover literally falls apart. This type of failure happens when either the cover has reached the end of its useful lifespan or something has happened to shorten its lifetime.

The plastic that the cover is made from contains antioxidants and chemicals to protect it from breakdown by UV light from the sun. These chemicals don’t last forever and as the cover ages so these chemicals get used up. The either the oxidisers in the pool water will break the plastic down or the UV light from the sun will. Or a combination of both.

This process should happen after about 6 years but sometimes it happens after only a few years. Why is this? In almost every case it is because of chemical attack on the plastic from the pool water. Excess chlorine in the pool water, whether for a prolonged period or intermittent periods, will attack the stabilisers and and deplete them in advance of their usual lifespan. Once the UV stabiliser is depleted by the chlorine the sunlight will finish off the job of breaking down the plastic.

What can I do to prevent this happening?

Many pool owners say that they do have too much chlorine in the pool and this may be so for most of the time but if you shock dose the pool and put the cover on straight away you will harm the cover. Sometimes you get high levels of chlorine under the cover but don’t realise you have done it.

Pool covers come with solar protection sheets to cover them when they are off the pool. These should always be used.

Roll the cover off the pool so that the bubbles are down. That way the sun can’t shine on them.

Are some covers better than others?

Yes. The higher the grade of material used the longer the life span of the cover. Three grades are available 400, 500 and 600 micron. This refers to the thickness of the material, the thicker the better.

The new Geobubble Swimming Pool Covers will last much longer not only because they are made from 500 and 600 grade but the additives are better and the shape of the bubble is such that it does not have weak corners that are always the first to fail.

So to summarise.

  • Don’t let the cover come in to contact with high chlorine levels when shocking
  • Make sure you don’t accidentally over chlorinate and if you do take the cover off
  • Roll it up with the bubbles down
  • Put the solar protection sheet on

Swimming Pool Design Awards

July 27th, 2012

The 2012 Swimming Pool “Masters of Design” Awards have been announced in America. The awards are split in to various categories and are only for pools in the United States. We thought you might like to see some photos of the pools. Some of them are not designed with sober European taste but they are all spectacular in their own way.

Keeping Cool & Staying Safe This Summer

July 9th, 2012

Last month brought us a wave of unsettling news stories and media warnings as to the dangers of being a weak swimmer, and the risks of drowning across the nation. Make sure that you and your family are kept safe this Summer while you beat the heat by brushing up on your swimming skills.

 

Swimming lessons are a compulsory part of primary school education today, with children in Key Stage 2 (aged between 7 and 11) required to be able to swim unaided for at least twenty-five metres. Despite this statutory requirement of the National Curriculum, it is still speculated that one in every three primary school leavers is unable to swim. Research conducted by breakfast cereal giant Kellogg’s, in association with the Amateur Swimming Association, has revealed that 200,000 students will finish year 6 this year without the necessary training to swim safely unassisted.

 

Of these children, 80,000 will not even have been offered swimming lessons.

 

Swimming Pool Safety

Teaching them to enjoy the water safely is one of the best gifts you can give your kids

This lack of concern shown for the importance of teaching kids to swim is contributing to a worrying rise of drowning-related deaths. Every year, the United Kingdom loses over three hundred children younger than age five in swimming pool accidents – with over three thousand others ending up undergoing emergency treatment following a narrowly-averted tragedy.

 

Keep your kids safe this summer – enrol them in a swimming class, if they’re young or inexperienced in the water, and speak to the headmaster or headmistress of their primary school, to confirm that swimming lessons are provided for students. Most importantly, though, never leave young children unattended in (or even near!) a swimming pool.

 

Children can drown in less than two inches of water, and may be unable to raise the alarm, if you are too far to see what’s going on. Never allow children to be left alone near a swimming pool, unless the pool is completely inaccessible (behind a fence or a locked gate, etc.)

 

But kids will be kids – and in case your little ones do manage to slip past you into the swimming pool area, keeping some basic but essential supplies close at hand down by the pool can avert disaster. Ring buoys are a flotation device that can be thrown to toddlers (or any swimmer) in trouble to prevent them sinking below the surface, and a reach pole is used to pull struggling swimmers to the side.

 

As vital as it is to teach children of the dangers the water can pose, it’s equally important to teach them not to fear swimming unduly. Splashing around in a pool is one of the greatest and simplest joys a child can experience, and swimming is a skill that can be of huge benefit later in life. It would be a great shame to have that experience go to waste.

The Zodiac MX8 swimming pool cleaner. A suction cleaner that does the walls

June 29th, 2012

New to the UK market in 2012 is the Zodiac MX8 swimming pool cleaner. It was launched in the US last year and has been getting some great reviews.

The New Zodiac MX8 Swimming Pool Cleaner

The Zodiac MX8 is unique among suction pool cleaners. The first thing you notice is the “tank tracks” at either end of  the unit it moves slowly along on these tracks and when it gets to the wall it just keeps going right on up the wall.

A look at the underside reveals two big circular intakes. These form a cyclone in the water to suck up the debris on the floor.

The internal drive system also means it keeps turning and moving and so it covers all of the floor of your pool (not just the deep end) and it should never get stuck in a corner or on the steps.

It has fewer parts that can wear out than other cleaners and a swivel head so the hose does not get tangled.

With a 2 year warranty we are quite impressed by this little machine.
