Huh they are but they just can't take lots of pressure if they are the combo res pump components I wouldn't trust the acrylic tube of the res that has threads cut into it to not crack in some way I wouldn't put more than a half bar or 5-7 psi I doubt most pump combo reses can even output anywhere near that pressure sustained without burning itself out, the only pumps I can see outputting that level of pressure are iwaki pumps or AC powered pond fountain pumps, stuff made to push water up 10+ feet through 10+ feet of tubing and still shoot out the top a few more feet for that pretty fountain effect people love.Originally Posted by andrewmp6
I found this a week ago https://modmymods.com/aquacomputer-dr-drop-pressure-tester-includes-air-pump-34087.html I did read it works but you can't have the pump in the system since they are not 100% air tight.
The pump better be air tight. As long as you don't go nuts with the pressure it's a good idea to test the entire system with air.Originally Posted by andrewmp6
