Pools & Spas
When I conduct seminars at pool and spa industry trade shows, I regularly get asked about the validity of a water-management technique known widely as the “acid column” approach. Those who believe in this application method say that if acid is poured into a swimming pool in a concentrated area – producing what adherents variously call a column, slug, well or cloud – the alkalinity of the water will be drastically reduced, but the pH will not drop as much as it otherwise would. By contrast, they say, if that same volume of acid is added by walking it around a pool and evenly distributing it throughout the water, the pH will be
For a while there, it seemed like most pool/spa combinations were being built with raised spas – that is, systems in which the level of the spa was set above the level of the pool, with the connection between the vessels made by means of a spillway of some sort. Recently, however, some of our clients have opted for a different approach in which the pool and spa appear to
Once you’re as well informed as you can be about the business practices of the companies that might end up designing and installing your swimming pool, the hard work of the decision-making process begins. It’s time, in other words, to bring a few of your candidate companies in, ask them to look things over and, ultimately, request bids for the work to be done. A quick heads up: The prices are going to be all over the map, and that’s because, if you’ve done things the way most homeowners will do, you’ve set up a situation in which
People who design and build swimming pools with attached spas are always on the lookout for ways to differentiate themselves in the eyes of the client. The spa, I think, is the perfect place to start. But the cold fact is that a great many watershapers who build spas do so very conservatively, whether out of habit or
It’s a case of familiarity breeding neglect: Pool and deck contractors work with so much mastic through the years that it’s easy for them to take this wonderful material for granted. And that’s a shame, because I’ve run into plenty of clients who are plainly interested in learning what function these rubbery joints serve and why they’re a necessary part of the package. The video linked below offers an
One of the things I like most about working with water is that it makes statements that don’t require much verbal explanation. In fact, I like to think that the projects I build speak volumes about my clients’ desire for something creative and interesting. They also speak to the point that most of my clients grant me the freedom to give my very best effort, both aesthetically and technically, without
Far too often, consumers approach construction projects in and around their homes as though they were buying television sets at a local mall. Nothing could be farther from reality! Let’s take a swimming pool as a case in point: Unlike an off-the-shelf commodity, a pool is a personal item that should be designed around the buyers, their lifestyle, how they entertain and – very important! – the nature of the building site. Also unlike most consumer commodities, the excellence of quality, design and performance is known to
‘I want the house to look as though it is floating on water.” That was what architect Victor Canas told me when I was called out to visit this site on the northwestern coast of Costa Rica. It was a brilliant idea, certainly one that befitted the spectacular mountaintop setting and its breathtaking 360-degree views of rugged coastline, forest greenery and assorted perspectives to horizons in all directions. I had the advantage in this case of already having built a
If you can’t see potential in every backyard you walk into, then you’re in the wrong business. Yes, some projects are more inspiring than others, and some spaces seem to offer you more to work with than others. Without exception, however, our clients’ yards present us with opportunities to develop programs that take advantage of what’s there in ways that bring balance and harmony and interest to any setting. Speaking for myself, I’m no more energized in a project than when I get the opportunity to right a wrong and replace a past mistake with a fresh, interesting design – and that was certainly the case in the project discussed in this article and in my past several “Details” columns in this magazine. The setting was special, the clients were great and
Of all the concepts of hydraulic-system design, there are few that have more importance than the correlation between water flow (that is, capacity expressed as gallons per minute) and line velocity (the speed at which the water travels). As water travels through a pipe, its increase in speed (that is, its line velocity) results in an increase in resistance (expressed as feet of head) and in a reduction of end pressure, which is measured in pounds per square inch (psi). In other words, an increase in friction losses and a drop in pressure is the result of increased water velocity at a given flow. If that makes sense to you without further explanation, then you know much of what you need to know when it comes to
