Hello, I got a brand new 29er and am running tubeless for the first time. Also new to Presta valves. I'm finding that I need to verify my tire pressure and top off before each and every ride, even if rides are as little as 7 days apart (bike stored in insulated garage). Is this normal? I thought maybe I got a bad tire, but it's actually both wheels.

Thanks for your help.

yes, and you should realistically be doing the same check if you're using tubes, as well. They lose pressure, too.

Yup. I check my tire pressure before every ride.
Well, maybe not if it's two days in a row. But it's not uncommon for my tires to lead down a pound or two in just a few days.
Whatever. It's like putting my shoes on -- I do this before every ride, too.

Yes 7 days is enough to lose pressure.

Have you put sealant in? But losing a bit of pressure over seven days is not too bad.

Seems normal. Mine do the same on both bikes.

I recently put on a set of Maxxis Ardent tubeless. I went a little light with the stans sealant. Rear tire needed about 10-15 floor pump strokes before each ride(daily) front maybe every 5 days. Drained sealant, shook sealant bottle better this time and added fresh recommended amount. Much better now. Those sidewalls definitely leak.
I'm switching to orange sealant btw.

29 x 2.6 xr4 holds air just fine, I check before every ride regardless. 29 x 2.4 xr4 goes soft with in a few days. I do have one plug in it. Fresh sealant hasn't helped either. Some tires just loose air faster than others I guess.

after a month or so, the rate of pressure loss will decline as the sealant works it's magic. I run at 21/23 psi and I find that I need to top-up every 7-10 days.
