I flush yearly but it's very clean every time.

The old and new unit are the same except LP/NG. Yes stainless tanks. No glycol this is for DHW. The burner is some sort of coper/nickel alloy.

So... My HTP light duty heat exchanger (NG) developed a leak. Took it apart and found the burner tube full of water. Cleaned it out and it slowly refilled. I was pretty happy with this unit and was using it for radiant heat in my basement floor and it seemed to do fine. So here's my weird...

I measured my BF, just as you did, @ .28GPM so you need to approx double your calculations. My total salt does is 16 lbs. for 48k grains. I contacted hach about the 30gpg limit and diluted with 1/2 distilled to measure. Multiple tests (including *not* diluting) give me that same 42. My...

I replaced the air check.

Updated OP with solution.

I do appreciate your input on this. I did return the permeate pump and asv90 and grabbed a 50gpd 1:1 pentair membrane and electronic shut-off and pressure switch. Everything works much better.

Ok this makes sense. IDK why my brain isn't working when it comes to this topic. I'm going to try a few things this week... I'll probably try without the permeate pump first and see how the TDS reads.

But how would you control the booster if also used with a permeate pump? It sounds like an ultimate yet expensive setup but the pump would run forever.

Apologies. My old system was a watts WP-4V and after looking at it I see there is an integrated ASOV on top. My new setup is a Ukoke RO8-L and I did remove the existing ASOV to replace it with the 90%. I'm aware of the different hookup layout of the 90% valve. I also bought the permeate pump on...

I think I figured it out. I need an electronic shut off for the supply that closes once the tank pressure is satisfied.

I bought the ERP-500 permeate pump and the ASV90 shut off valve after reading quite a bit here. It doesn't come close to the pressure/flow my old watts setup with an aquatec booster pump had. I still have the aquatec pump and would like to utilize it for maximum pressure on this new system but...

Go to the pentair website and send them an e-mail. The guy I worked with was super helpful.

I had some weird problems with mine too. Settings would change on their own after a power fail. Pentair tech support had me do a master reset and all was good after that. Hold the extra cycle button while powering up the valve. This will wipe everything so be prepared.

That makes sense. I guess I'll let it BW one more cycle then replace it.
