Central vac related question

[dh_ld]

Hi,

I'm afraid I work installing central vacuum systems. When we install vac pans we use a flexible rubber hose called VAC-U-FLEX, made by Flexible Technonogies. I started using it at other times too, when it's hard to get regular fittings down through the floor...it can save a lot of time hammering and chiseling, and then trying to get the fittings down through the hole. I told the boss about that, and he said not to do it. The reason is because the tubing supposedly breaks down after about 10 years, and if it's in a wall it's hard to get at and replace. When I asked him why we use a product that breaks down in 10 years on vac pans, he said because we can usually get at them to replace the hose. I don't think so, but we disagree about many things. The question is: does anyone know if this product really does break down after about 10 years, and if so, is there a similar product that does not?

Thanks for any help! David

The flexible hose is a LOT more expensive than the regular pipe.

The obvious answer is your time is less valuable than the flex hose saves.

Note: If the flexible hose is corrugated it will be more likely to become clogged.

What does the manufacturer say? What does the National Bureau of Standards say?

The National Bureau of Standards went away many years ago to be replaced by NIST. Last time I was there they were not in the vacuum cleaner business.
