Definitely. I'll also do some MS Paint drawing, that's sometimes easier to grasp than a photo of some dark equipment corner.
Even now, without the float valve, water changes are more funner.
Open a lil ballvalve to drain the water, then open the saddle valve to fill 'er up. Just need to remind myself to turn it off again.
Still waiting for the float valve. I love Big Als, takes them only like 3 weeks to get something to you. This is how you learn to become patient!
