The Silly Stuff!
"Only our spas are rated for use by the
Arthritis Foundation." This was told to me by a woman with
was about to buy one of their spas, based upon the salesman's false implications.
First of all, arthritis is a painful disease. Not fun at all. I don't understand why some sales guy would play on a person's pain like that! Why not be truthful? I know that is a difficult thing for these sleazy people, but how do they live with themselves.
It has been my understanding from talking with sufferers of this affliction that the water jets at times may not be the best therapy for inflamed joints, depending on the type of arthritis. In hospitals, they use bubble therapy most of the time, because it doesn't apply pressure to an already sore joint. Or they use a whirlpool of low pressure water.
The spa this sales guy was trying to
sell has no
air bubble jets at all. It is not even built to the ANSI Safety standards. The woman would
have to just sit in
water in order to not have jets on her sore joints.
I would like to see all spa manufactures not use any medical ailments as part of their sales propaganda with the implication of any superiority to any other product for the disease. It is a low blow to the industry to imply that only their spas are good for arthritis! Let me give a clue here:
tubs are good for
arthritis! Blower therapy is preferred, because it doesn't
apply pressure to inflamed joints.
The other issue with this company is that they
publish the Arthritis Foundation Logo on their website. I have to
tell you just how "skanky", low life, and
disgusting that is. It is against the BBB Advertising guidlines
to put "implied indorsements" by a not for profit organization in any
form of advertising. It is also against the FTC guidelines for
advertisers to do so. The disgusting implication
is that these cheaply made overpriced spas have some superior arthritis
effects over other brands of hot tubs (Most spas are better made than
these inferior products.). It is really very bad.
The Arthritis Foundation is unprofessional and
inconsiderate of poeple with this disease, for allowing
this. Are they going to be the whore of these spa companies,
becasue they get contributions from them?
Any company who uses charitble conrtibutions as a
way to sell is disgusting. I never ever publish my charity
contributions as a way to sell something. It is against all
morals and ehtics to do so. I never solicit any person from
church to buy from me either. It is against morals and etics to
attend church in order to make money from people coming to
worship. This is all in the same "basket" of weak people
who can't operate a business ethically. If a church member
approaches you for professional help, that is different. But
never hand out business cards at chruch, or solicit people for sales
there. I just don't understand how people get so screwed up because of
(another type of joints altogether)
Here is another pitch that has been around too long. "The full foam holds the plumbing pipes so they don't shake around and leak at the joints".
When I was taught how to plumb a spa, we used primer and glue to make the joints not leak. I have seen loose flex PVC, just hanging there is spas over 16 years old, right at the pump where the pressure is the greatest. Please don't believe that one!
Actually the best way to keep the spa from leaking for the longest time is the use solid PVC as much as possible. On smaller tubing it is a good idea to place them in foam or to tie them. If a pipe is moving inside the spa it needs to be tied or held, but full foam is not needed for any spa design.
"There is no such
thing as 100% filtration in a hot tub or swimming pool."
To illustrate: If you take a bucket of dirty mop water over to the sink. Then dip in with a cup and pour out one cup of dirty water and pour in one cup of clean water; stiring it and mixing it with the dirty water, eventually it will become clear after many thousands of cups of water are poured out and clean poured back in.
If there was 100% filtration, you would have all of the water removed, pumped out, and then filtered as it would be pumped back in, so that 100% of the water was forced through a filter as it returned to the spa. I supposed if you wanted 100% filtration, you could buy a water tank to hold all of the spa water.
Whenever the term 100% filtration and a tiny circulation pump are used in a brochure, it becomes consumer fraud, or extremely close to consumer fraud. This is only one of the several reasons why the tiny circ pump is ridiculous engineering.
The best filtration available today
modern two speed pump on low speed 35 to 50 GPM, using a check valve on
open suction in the bottom that closes when the pump is on low
speed. When the pump is filtering with this configuration, a lot
of water is moved quickly into the filter.
Now, 2005, we have full size super energy efficient 48 frame
and 56 frame real, circulation, water pumps that move 35 to 40 Gallons
Per Minute for up to 24 hours per day.
Filtering is a long process, because as the filtered water returns into the spa vessel, it is mixed with the other water containing debris. As the water circulates, gradually more and more particles of debris are filtered out. We have found that six to eight hours per day (15,000 to 25,000 gallons per day) is required to get good clear water with most of the debris filtered out.
The common method of so called "100%" filtration is to completely block the suction of the spa pump with a filter, and not allow any water to go into the pump that is not passed through the filter (no check valve). There are a couple of engineering problems with this. 1/ The jets get weaker as the filters get dirty and clogs up. The only time the jets have full pressure is with brand new filters. 2/ The worst thing to do with a pump is to block the suctions and give the pump more work to do with less felt jet pressure. This increases electrical usage and your electric bill. 3/ It violates the ANSI safety standards for portable spas.
I have had customers bring in filters
that are caved
in on the sides from the pump trying to get water. The
time I saw one of these filters, I knew there was something wrong
this filter system, so I started my investigation.
