Rodi unit tds question

[TanknTang]

Hi guys I got a 6 stage rodi unit and a booster buddy from brs for christmas, I have well water and got it all hooked up, etc. I took all the valves off that the booster buddy says to remove so no purge valve etc. However my TDS on sensor 1 comes in at around 7ppm and the 2 and 3rd are 0ppm. When I go to double check the tds reading with my handheld I am getting 3ppm in the bucket... the handheld is a honeforest I got off amazon. Does this seem like I hooked the rodi up wrong or should I go off the tds meter on the rodi or trust/not trust the handheld meter?

thanks for any direction

Also my psi with the booster and well water is at 80psi then will drop to 60 and then go up to 80 again repeat.. is this normal? Its almost like it builds pressure and then drops

If you used the bucket for saltwater the residew in the bucket will raise tds

Agreed. Use a clean container rinsed several times with RODI water before testing a sample.
