Doser tubing replacement interval?

[Velodog2]

Can't seem to find info on this. It's certainly not in the silly instructions that came with my Jebao doser. I'm only using two of the four channels so have the two extra tubes as replacements but have no idea how long they should be expected to last.

Are there any generally accepted guidelines or anyone have experience to base some on? I would rather not run to failure.

I believe brs says 6 months or a year. I would buy backups at around 8 months and change when they crap out.

I've read yearly for the brs dosers. Mine are approaching the one year mark and show no signs of wear, and still work fine. I purchased backups this month anyway just to have some on hand for when the time comes. It's funny, enough time passes in the hobby and you stop collecting toys, but instead you begin collecting spare parts and backup toys

That is helpful. Thanks.
