Pool jets are what keep water moving in a pool. Without that pool circulation, the water would quickly grow algae, collect dirt, and not be anything you wanted to swim in.
They're called return jets because of how the chain of circulation works in a pool. Dirty water gets sucked out of the pool via the skimmers and main drains, it then goes through the pool filter system, before being “returned” to the swimming pool by the jets.
Position the Jets
A pool typically has two to three return jets where the water that filters through the circulation system returns to the pool. For effective circulation, it helps to have these multidirectional jets, because they allow you to determine the direction that the water returns to the pool.
Return jets
The jets should all point in the same direction, ideally at a 45-degree angle that's directed toward the bottom of the pool. One way to remember it: Point the jets at 4 o'clock or 7 o'clock and ensure that the jets are not pushing water toward the skimmers.
How much does a swim jet cost? Swim jets typically start at $2,000 and go up from there with additional horsepower and features. On the high end, there are swim jet systems for professional and Olympic athletes cranking out 7.5 horsepower or more that can cost nearly $30,000.
The pros of deck jets are plenty. Putting aside that they're visually pleasing, they add a lot of tranquility to your outdoor space. In fact, when you're in the pool, the sound of the water arches will drown out most outside noise, aiding in relaxation.
The swim jets do give you a good workout, but are not a good way to refine your strokes. Make sure you get one with a wide adjustable flow range so you can tailor stroke and effort to your needs. I do prefer swimming in full size pool, and some people just can't get the hang of swimming in place.
While many professionals install two returns, some prefer more as a general rule. Builder Guy Wood, for instance, often will place four returns in pools that measure 250 to 600 square feet. A vessel of 600 to 800 square feet will generally have six returns to start.
If you want stronger jets, you need to increase flow rate and/or pressure. Assuming that your plumbing can handle higher flow rates, a larger pump would make for stronger jets.
If you are without power, grab your pool brush! Not only will scrubbing the sides and bottom reduce or prevent algae, it also causes the water to move and circulate, helping maintain an even level of chlorine throughout the pool.
A seiche, pronounced "saysh," is an atmospheric phenomenon that causes bodies of water to oscillate, the National Ocean Service explains. ... Others have contacted us with a different explanation: A low water level causing a pump return to spray water onto the surface of the pool and start the waves going.
Pool circulation systems work much like the body's circulatory system. Water is drawn from your pool by the powerful suction created from the pump. The pump draws the water through the skimmers and drains, removing large debris during the journey.
Main Drain
Main drains are usually located at the bottom of the deep end of the pool. While the skimmers take care of pulling water off the top of the pool, main drains are great for pulling water off the bottom.
If an in-ground swimming pool is constructed of concrete, it will need coping, which is a cap for the edge of the pool. Besides simply being necessary, the coping provides an opportunity for a decorative accent, which can greatly enhance the appearance of the pool.
It's important that pipes are buried deep so that they don't freeze. It is usually 3 to 3.5 ft deep.
Running the pump at night should only be when you are doing a major chemical treatment such as algae clean-up. Your pool is more vulnerable during the day, plants don't grow at night the way they do during the day–that's true of ALL plants including Algae.
The main drain is the primary way that water is drawn from your pool into the pump and filter. The main drain is located on the bottom of the pool in the deepest part. Most pools have one, but larger pools may have multiple main drains. Main drains must be protected by an approved cover.
The general rule is that 10 PSI above the normal operating pressure is considered high. A high PSI reading should be addressed quickly. Damage to the filter, pump and plumbing can occur if high PSI is sustained.
The level at which pool skimmers function properly is between one third and about half way up the opening of the pool skimmer. If the water level is too high the debris floating next to the opening may pass by without being pulled into the skimmer.
Fitness swim jets can be custom-built into new pools and spas, or added to an existing pool. Now you don't need a large pool to incorporate swimming into your exercise routine. By generating a current, swim jets provide the fitness benefits of a full-sized swimming pool with less maintenance and at a lower cost.
With no pumps or plumbing, SwimJet has a clean, simple design and is easy to install in new pools. The strong underwater current turns even small pools into Olympic sized ones and suits any strength of swimmer, from advanced fitness training, to a relaxing paddle on a hot afternoon.
The Fastlane swimming machine produces a smooth, quiet, powerful current that's perfect for any backyard pool and it's adjustable from zero to 1:10/100 yards. Now you can turn any pool into an Endless Pool! For fitness or fun, the Fastlane swimming machine adds a whole new dimension to your pool.
