That doesn't remove all liability, though. Remember Joerg is in Kalifornia.

Well, not in all countries, of course, but at least over there. Kenya is one of the more enlightened African countries. As I said, my brother's issue wasn't with the Kenyian government or with their people.

When >it lost its "blueishness" it began to flake stuff into the pool. Yeah, we use one like that. Or, rather, we use one of those every 2-3 years... that's about all they're good for, in practice. The "warranty" is for five years, but it's voided if you expose them to more than about 1 PPM of chlorine in the pool water. I considered switching to one of the non-chlorine systems to preserve the cover, but the most popular one (Bacquil) isn't compatible with roof-mounted solar pool heating systems as it'll generate massive amounts of foaming and bubbline. The guy at the store recently admitted that nobody gets five years out of these things, because you can't keep a pool properly and consistently sanitized with such a low free-chlorine level. This seems to be especially true at the higher water temperatures that these covers are intended to provide... we run our pool near the cover's rated upper temperature limit of 90 F (my wife likes to swim in soup... it's so warm I start overheating if I swim fast laps). I just consider the cost of the covers to be part of the ongoing expense of operating the pool. They add a couple of months a year to the swimming season. -- Dave Platt <dplatt(a)radagast.org> AE6EO Friends of Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
