Auto Top Off

[Luckylouse]

Guys, What is the best method for auto top off using the Profilux?

I have a dosing units, Could I use the optical sensor tied into the 4 pump on my doser?

What do you do?

Best option is solenoid valve in line with the RO unit on the inlet side (to avoid back pressure)

set socket to water 1
set level 1 to ATO
Plug solenoid into assigned power socket

This is the simplest ATO

or you can use the method you have suggested.

Careful..

Careful..

I used the doser for a few months just like your talking about... Those pumps don't seem to be able to handle all that water. Mine was wearing out and quick.

Going with a solenoid sounds great... Wish I could get one, maybe soon...

In the meantime, I bought a small pump and put it into my RO water tank. I set the outlet to the topoff and it turns on my pump when it needs water and off when it is full.

$15 pump and I was done...

Hi

Unless you have some significant evaporation for auto top off dosers are fine, however this does depend on how much water you are losing during the day.

A simple water pump is indeed cheaper and this then leaves a doser pump for more important duties.

What water pump would you suggest.

cheapest possible

I still love my neat and tidy option of solenoid directly off the RO unit though :dance:

Me too but it won't work for me right now. Maybe down the road.

Like he said...Cheap as possible...

I used a little 80 or 90 Rio... My top-off water is level with my sump therefore I did not need any power - just flow.

Remember to set your "time-out" function. If you run out of water in your top-off, then the pump will only run for 20 - 30mins before the controller will shut it off. You decide how long...

I use a MJ400 it seems to do the trick. The one issue about a solenoid of my RO/DI is that it is a real inefficient way to make water. It is better to make a about 1-5G at a time. I do this by having a small 5G holding tank for my RO/DI Every day for 2 hours my solenoid is switch on filling up the 5G tank using one level sensor. I then have a MJ400 topping off the water.

Ah.. ha... Nice.

I like the aqualifter for a top-off pump since its flow is very small - probably similar output to the dosing pumps (don't own those, so I'm just guessing). They aren't expensive. I have two that I plan to connect for some extra reliability. Only one is connected right now.

The GHL doser flow is as little as 1ml a day, so for small nanos this is an option to use and would not put to much burden on the pump.

Hope the info is of some use

Always interesting to read how different people set up functions

 

[tnoblett]

Where?

Where?

Where is everyone getting their holding tanks from?

I want to move into mixing my own salt, then start using the top-off to add water and change water.

Any dealers or just use plastic trash cans...

I bought the doser to do water changes on my tank, about 5 gallons a day in/out then to add about 5 gallons water for evaporation.
It disappoints me to hear the Profilux doser is incapable of doing this without "wearing out"
Maybe I should buy a cheap aqualifter to do what the profilux can't..
