I think they should let it sway there decision...because circ pumps do create less wear on the main pump which is now being used for filtering, heating and jets. This is also a less efficient way to run a hot tub because of it...Marquis wasnt bought out that long ago and when they were they took the circ pump out. 3 main hot tubs are hot springs sundance and d1, all use circ pumps...but marquis does not. They also dont use pillows, or a wier system. Marquis sales people are always telling funny stories of what people do or don't like but really Marquis tries to reinvent the wheel to make themselves different and if the story is told by a strong enough sales person it will sell.
You really should only make rebuttals on items you know about and it is apparent spas are not that.
You state circ pump creates less wear on the main pump, I can say circ pump adds another part to the spa and all the manufacturers know the Laing 909 are one of the higher warranty items.
Less Efficient you say, at .10 cents a kilowatt hour a circ pump will cost approximately $4.50 a month the run, our filtering pump will cost about $4.50 a month the big difference being is in that month we filtered 720,000 gallons that month and the circ system filters 302,400 gallons. We filter more water for roughly the same money so who is more efficient?
Yes we were bought by the employees on 1999.
We offer pillows as an option, as no one warrants pillows past delivery we chose to be up front with customers so they have no misunderstanding that they are part of the spa warranty.
You say we do not use a weir system, do you even know what a weir is for, it is designed to help break the surface tension of the water to aid in filtering. If you look at our system we skim right at 60" of surface area most everyone else does 12".
