Ok I realise its a bit of a “how long is a piece of string” type question, but I’m curious as to how well peoples RDTA’s have held up over time… I’m currently using a couple of voopoo rimfires (abt 6 months old).
For example, I had (still have) a couple of Aspire tanks (triton mini, atlantis evo, and clieto - in that order) and apart from having upgraded over time they are all still more than serviceable. I’d say that each one has had between 1-3 years of usage.
None of those tanks came with spare anything (no seals, extra glass - nada) and even though were used for quite some time, they never needed any parts replaced (and besides were cheap enough that had that been needed, then I could have just brought a new one).
Now some of the rdta’s and such like are quite expensive, and others are not much more pricey than the aspire kit, but most come with spare glass and quite often a full set of replacement o-rings and seals and whatnot. But has anyone, who uses kit for a fairly long period of time, ever needed to replace a seal or even replace the glass (barring accidents like dropping it on the floor and breaking the glass blush)?
It seems that with normal/moderate use these things should last for years, if not kinda indefinitely, especially with all the spare do-dads.
So what’s the longest peoples RDTA’s (or other tanks) have lasted? Still going, and still in daily use?
I guess drippers would last the longest (nigh on forever) as apart from the seals, the only other bit I can think that would fail would be the insulation (cracking/disintegrating) on the deck or the insulation between the shell and the positive screw.
[edited to add] I guess rubber seals would also break down over time (we’ve all seen aged rubber bands that have become brittle but that tends to be for different reasons), but the silicon ones theoretically should last longer.
