If so, what would be the expected life of the internals? How often, running at 6 times per day, do I need to remove the cover and check for wear. I believe the screws for the caps are just going into plastic and that will probably wear. Maybe just the tubing replaced on a regular basis, failure or not?
2. The new head covers are "Fast". They must be re-calibrated. One of my pumps is now actually 10 mls/min faster then it ever has been. All increased with the new covers. It is also visually obvious when running that they are smoother and faster.
3. You just gotta remove that air filter.
4. I need more parts! :-) Also, stock the screws. Tiny and difficult to handle. I keep a fish net with neodymium magnets in it to find and retrieve them when dropped.

Hi Jeff,

1. The screws themselves will not "wear out". The only parts that will wear overtime (depending on usage) are the blue cap, rollers, and tube. The tubes should last you quite a while. A good replacement indicator is when the tube begins to harden, crack, or become more yellow. Personally, I like to replace these at least once a year. The caps and rollers should be regularly cleaned every 3-6 months. The key is to make sure you're not accumulating excess dust because that will eventually put more strain on the moving parts and motor.

2. Since these v2 caps are sturdier and slightly different from the originals, re-calibration may be necessary.

3. Yes, we found that some users encountered issue where the filter would become clogged and result in trapped air which blocked the VENT. After looking into this some more, we decided to no longer include these vent filters because they did not provide much more of an added benefit.

4. We'll take this into consideration.
