LLC-M for RO/DI

[vokey60]

Scott,

I recieved my unit and I understand how to hook it up but I have a couple of questions.

1. When I talked with you onthe phone lastweek you said this was the unit I needed to keep my sump at the right level plus when I need to perform a Water change. this is the part I don't understand. I make a water change every 2 weeks right now I just turn my RO unit on and let it run until I have the amount of water I need, with this unit how do I do this. If i hook this up like the diagrams read, when the sensor has the right amount of water in my sump it will turn off the RO/DI unit if I want to make 30 gallons of water how do I do this? I see the ball valve after the 4lb check valve I know you just open that up but how is it going to produce water on demand If the unit is off. I really don't want to hook the float valve up to a trashcan and store the water I want to be able to make water only when I need it.

2. Will I have to use the Mini bladder? What's the purpose of this?

Thanks David Browner

David,

In addition to the evaporation top-off of your tank, you want to make 30 gallons of water but you don't want to hook the float valve up to a trashcan and store water, you want to be able to make water only when you need it.

I'm not sure what you mean or what you want to do.

If I spoke about a Water Change, I certainly meant to make and store water long enough to add salt to it so you could do a water change.

If you have our LLC-M system,
and it's hooked-up as shown in our diagrams with the check valve and ASO valve mounted on the RO unit,
and the LLC-S is installed at the sump,
then any floats you connect to the supply line below the tee will operate the ASO valve and therefore the RO unit.

The Mini-Bladder helps a float provide a more positive turn-on and turn-off action.

Scott,

I don't want to hook up the bladder or a float switch after the T I just want a ball valve that I can turn my RO unit on and get water when I need it. My question is when I hook up everything @ my sump will I be able to get water by just turning the ball valve?
Also mounting the float switch at the sump I quess you have to drill a hole in your sump to install these that's something your diagrams don't show how would you install the safety float switch @ the sump.

David,

To answer your first question, the answer is yes. A ball valve, or any kind of valve, can be used. When you open the valve, the pressure is reduced in the product line and the ASO turns on. When the valve is turned off, the pressure builds and the ASO shuts off.

To your second concern, you could mount the float through a piece of plexiglas and then use aquarium silicone to fix it to the top edge of the glass sump. Carefully bend the stainless steel arm of the float further down so it still shuts off before (or if) the water gets too high. Another trick is to make a "clothes pin" out of two pieces of plexi and the threaded body of the float valve. Position over the top edge of the sump and tighten the nut on the float till the assembly clamps tight onto the sump glass. A little silicone wouldn't hurt here, either.

Scott,

Great answer on the ball valve just what I wanted to do thanks!! on the float valve 1st I know the sensor is what shuts the water off so the float is just as a back up correct? DO you guys offer a float that you can just attach to the top of the sump and let it hang down say around 4 or 5" that would be what I really need the space under my stand is limited on space and getting in there to mount the float with your idea will be very hard I would like something that works like the sensor that just hangs off the inside with a clamp or suction cups is this possible I assume the feed water runs thru the float correct? Please lmk if I can do this.

David,

1st question: you are correct.

2nd question: The same float can be bent so as to mount on a horizontal plane (instead of the vertical wall). You would have to clear the top of the sump and right-angle onto the top-mounted float. You still need some kind of plexi bracket clamped or glued to the top edge of the sump.

3rd question: you are correct.

Scott,

Ok I understand, I have 3 holes drilled in my sump now for RO/DI and any other things you might want to add but the holes are 1/4" that will accept a regular 1/4" fitting but the threaded end of the float will not go thru it. What size bit would you need to drill for the float to go thru and still seal when you tighten the nut? I have a LifeReef Sump and it's acrylic and I have never drilled thru this material. The 3 holes I have are only 1" above my water level I'm just thinking that I could enlarge 1 of the holes if I knew waht size bit and what type of bit. If you know this please get back with me.

thanks David

Scott,

I hope this is my last question, When I turn the ball valve on to dump some water into my trash can for water changes the sensor will not turn the water on to fill my sump. The sump had dropped around 2-21/2" and no water. I went out in to the garage and closed the ball valve and then the water started dumping into my sump. Will this system not fill both at the same time? If so please tell me what the problem could be. I talked with a Tech person today at SPectrPure and told him that when the water did turn on in the sump it would spray a stream about a foot into the sump then slowly go to normal pressure he told me that I was dumping the bladder and suggested that I move the 4LB check valve in front of the bladder and that would stop the problem. That's the only thing that is different from the diagrams. I have excellent water pressure please lmk what you think.

David,

1st question:

Swap the two check valves. I think you got a pair that weren't marked. The #1 CV is before the ASO valve and the #4 is near the bladder. You can blow through a #1 but not a #4.

2nd:

There are advantages in both ways: bladder first or check valve first. You'll do better with check valve first.

Scott,

That's the way I have it #1 is before the ASO and the #4 is before the bladder, I would like to fill both at the same time if I can, Does the system do this?

David

David,

With the #4 CV on the bladder side of the Tee, priority is given to the sump through the LLC-S.

Without the #4 CV, both outputs have equal priority, and the path of least resistance wins.

Ok with that said I have the #4 on the bladder side if the Tee but my sump doesn't have priority. I was filling my trashcan lastnight for makeup water and checked my sump it was 2" low and no water I closed the ball valve after the bladder and then I had water @ the sump I also have the LLC-M so I thought this would enable me to fill both at the same time. What can I do to have this happen.

David

[SpectraPure]

David,

The only thing it could be is that the #4 is stuck open. Buy, if you can't blow through it, water won't fall through it if the water sees less resistance through the open LLC-S.

Check valves VERY rarely stick open.....

This is a very strange one and you should probably call us and get another #4 CV.

Scott,

Well I can blow thru both Check valves so you were correct #4 is bad my only problem now is which one is the 4 or the 1. Can you have them send me 1 of each and have them marked that way I know I'll install correctly and get results.

David,

Please call our sales line, tell them you talked to me, and they will send 2 new properly makred CVs.

Sorry for all the confusion,
