Merlin's work best over 55psi,... TDS rises dramatically below this.

I run my merlin at between 35 and 40 PSI.  Not ideal but it will have to do.  The TDS started at around 006.  I needed to restrict the waste for logistical reasons and the TDS climbed to around 015.   18 months later it is around 025.  I find this acceptable though obviously not ideal.  I would like a bit more pressure but I don't want to go down the pump route.  Due to the tank's setting, it is very important that there are no leaks or overflows.  I've already had one cut off switch fail on me so prefer to rely on a ballcock system for shut-off.
