Aqua Lifter and Kalk reactor

[mikesommers]

Anyone using an aqua lifter for ATO with a Kalk reactor? I am working on adding the reactor to my system. Was looking at an Aqua Lifter to replace my existing pump. I have hopes that they would except the same type of line as an RO filter?? There is really no lift more than 2 feet. Then it would push through the reactor. Also was wondering if they will siphon back into my revisor or not when it shut off? It does not seem like it could being that its a diaphragm pump with reed valves. Does anyone know about these?

A check valve takes care of any possible siphon issues.

Correct on both of the above. And an Aqualifter will accept the RO/DI line just fine.

The aqualifter will back siphon....FYI

The input tubing to the pump should go into your reservoir of RODI water. Connect the outlet of the Aqualifter to a short piece of 1/4” tubing and install a tee fitting. One of the tee connections then goes to your kalkwasser reactor and the other should be secured several feet above the water level of the top off container (this is used to provide a siphon break). Your pump should be positioned so that it is located above the RODI reservoir.

I guess my biggest concern is were to locate the RO/DI input on the reactor. I am building the reactor. I guess I need to know if I should worry about a check valve between the aqualifter and the reactor or just mount the aqualifter above both resivor and reactor. The point is to be able to allow the fresh ro water to enter the reactor low and the kalk mix to gravity feed from the top to the sump. So my concern is that I build my reactor that I understand how my feed to it is going to work. It's cheaper to ask! If someone says add a check valve I will. It sounds as if I will not need one though.

I just kept the end going into the sump out of the water and had no problems for 2 years. Then I upgraded and everything larger UGH!

Rawn is right!

Keep the AL higher than the RO reservoir and you don't kneed a check valve. But also make sure the end that empties into the sump is open to the air and not below water.

One thing that you may run into... I don't evaporate a terrible amount, but an AL through my kalk reactor (which is about 2.5-3 feet away) could not keep up.
Even after I switched ATOs (so that I was using one that would not time out), the AL would run all the time and couldn't fill the sump up to raise the float switch.

I will add a check valve it $0.70. That takes care of that.

I have read this somewhere else. How much lift did you have. I have about a 2 foot lift then everything will almost be down hill from there. If thats the case sounds like a Maxijet mod is coming!

My concern is a 3 foot reactor with a feed halfway down. The siphon will break on the outlet of the reactor but would 8 inches of kalk still end up running back into the resivor?
