NO. If you are currently using chlorine (or bromine in a spa) the Sigma III can be installed without making any changes to the water. The chlorine will slowly dissipate, and you will have a chlorine-free pool in no time. If you are using some type of alternative chemical, like Baquacil, you will need to put in certain chemicals that neutralize the Baquacil before putting the Sigma III in, much like converting back to chlorine. You should be able to find those chemicals at your local pool store.

Avoid draining the pool if it can be helped. Sometimes draining your pool can cause irreversible damage to liners, cause pools to float out of the ground, damage to decking, and etc. If you think you need to drain your pool contact us for advise before draining. A complete draining may not even be necessary.

YES. The Sigma III Pool Purifier is used all over the world in public pools. In many areas the local health department may still require you to use a minimum amount of chlorine in a public pool setting. The Sigma III works great with chlorine, in fact, most public pool facilities have noticed that they use 60-80% less chemicals with the Sigma III. Patrons will notice a difference, and will comment that the water feels as though there is no chlorine in it.

Yes, you do need a permit to drain your pool. They are free and can be obtained on-line or by calling the pool drainage hotline # 480-350-8521. The permit is valid for 30 days from the date of pick up. for where can you drain it, you have several options; if you know where the sewer clean out is "on your property", you can drain the pool into it. If you do not know where the clean out(s) are located, you can usually drain your pool into the gutter on the street.

Answer: Yes. This is a separate inspection done by the plumbing inspector and needs to be requested on the pool permit.

The Town's Pool Enclosure By-Law requires the installation of fences around a swimming pool. (There are some instances when this requirement is exempted - please contact the Building Section for more details.) It is the installation of this fencing for which the permit is for, not the actual installation of the swimming pool. The reason for a fence is to help prevent any accidental drownings in above or in-ground swimming pools (including hot tubs and spas).

The purpose of this 'Frequently Asked Questions' page is to provide answers to the questions most commonly asked by the public.

During the dry season, definitely not. If we get enough rain at this time of year to overfill the pool you can rest assured it will not last and within a very short space of time the water will evaporate off again. During the wet season I only recommend you drain the pool if it is going to overflow to somewhere that you don't want the water to be (like your lounge room!) or if there are lots of leaves in the pool that need to be skimmed off. This could be a number of things.

No, let the computer do your work. As discussed in the lab, you will want to add some methods to the open addressing bucket mapping implementation to support this (e.g., a method to return the actual load, a method to reset and get the value of a probe counter). For Part III, you will also want to add a method to return the actual load. The lab does talk about this, so perhaps it would be good to reread the assignment.

Pool and community gate entry device policies vary from community to community. You will need to contact the Tri-City office by calling the TCPM office at 480-844-2224. I am planning to leave town for a few weeks. The last time I left town a pipe ruptured in my unit and flooded my home as well as my down stairs neighbor. No one contacted me to let me know. How can I avoid this in the future.

Some locations are easier than others, but RenewAire can be installed almost anywhere, as long as they are accessible for changing filters. Even better, a RenewAire unit can be installed in any convenient position, because there are no drain pans that must be located at the bottom of the unit.

Six Sigma stands for Six Standard Deviations from the mean which implies to a system that will produce less than 3.4 defects per million. In practical terms Six Sigma is a methodology that provides the techniques and tools to improve the capability and reduce the number of defects or opportunities for defects within a process.

All public swimming pools or spas are required to have a permit to operate issued by the Environmental Management Department, Environmental Health Division. Private pools and spas are those which are intended for non-commercial use and are not used by more than three owner families and their guests. Private pools meeting this requirement do not require a permit to operate from our Department.
