Welcome to our forum.
There are a few factors re: Â cover longevity:--Location--Is it in full sun all day? Â Is is subject to "tree trash"?--Quality--Covers differ greatly in construction quality. Â I would guess that most manufacturers have theirs made by another company. Â Retailers might chime in if they know of specifics re: their brand(s).--Maintenance--Is the cover cleaned regularly? Â Is 303 Protectant used regularly to condition the vinyl?--Handling--Is a cover lifter used as opposed to dragging the cover off the spa?There may be more considerations but these are "first out" for me.My cover would have lasted more than 4 years had a tornadic wind not deposited it in my neighbors yard. Â I've ordered a custom cover here from the good Doc and am anxiously awaiting its arrival. Â I'm sure it will be MUCH better than my original cover even though it would have survived nicely even with direct sun all day for 4 years this July.HTH... 8-)
When I shock the tub I always have the cover open.
There is nothing wrong with the vinyl on the cover. I assume thats why all the questions.? Correct me if I'm wrong. My cover is saturated with water (it is very heavy (wife can no longer lift it) even with a cover lifter). When I shock the tub I always have the cover open. What can be done to prolong the life of the cover?
If your vinyl is still like new, buy a foam insert only. Will save you some money. 8-)
Open, or OFF? If just open, the side facing the spa will degrade and become heavy.
