autotopoff.com mmmMMm whatcha say?

Great stuff/prices. Lots of people here have used them. I have the double switch unit on my sump, and a solenoid valve from them on my RO/DI.
 
I own 3 of the doubles. 2 of them are over 5 years old. Never had any problems with any of them. I highly recommend them. good quality at a great price
 
I purchased the Autotopoff.com automatic top up system with double float in early 2010. I installed it as indicated and it was working fine. 2 weeks later, the valve malfunctioned and opened. This caused my tank to overflow for some time and caused water damage to the floor, surrounding walls and my 220 gallon tank stand. If you have ever had to move a 220 gallon tank, you know exactly how frustrated I am right now.

To make matters worst, after months of emails back and forth and empty promises, the owner refuses to refund me my money on this terrible unit. All he wants to do is send me instruction after instruction on how to repair it. It was a 2 week old unit, I shouldn't have to repair it ... wouldn't you agree?

I thought I should share my situation so that everyone knows how horrible the product is and to also let you know that the service is even worst.

Thanks for reading,

Good products, yea, good prices too, especially if you are a DIY kind of person. I have been using them for years and never got water in my stand or floor - ever. And, like Coaster said.. double float is highly recommended with the second an inch or so higher, so it normally isnt in the water and less subject to things that build up, so always ready to 'catch' the level if the first has a problem. GL!
 
Ive been using a double float since start-up of tank (3 months) and zero problems. Return area is 8"x22" and holds the water with 1/16 of an inch. Adds about 2 cups of water every time it comes on, if I had to guess.
 
I got the double float and love it!!!

This is what I got

Only time it didn't work was when I ran out of RODI water in the top off bucket...doh :hammer:

Here...I'll add some pics:

Topoff bucket. I did get one of their pumps to use to pump the water. I just got a clear tube that would fit on that and the hose fit perfectly into a square on my egg crate top to hold it on. Top off bucket is just a Reef Crystals salt mix bucket. I drilled a hole in the lid just big enough to fit the hose through.

Friends love them.. lol guyacrosssdstreet.. only has 2 posts.. both of them the same story... and in the other thread he said he paid $200 for it.. ridiculous.. mods? look into this?
 
I have the double float switch and been operational for approximately 10 months.

The secondary float sticks a little at times, but I have the first and second float with no room to spare between them. It works though and that's the main thing! \

The good:

1. reliable top off!
2. easy to setup!
3. virtually maintenance free.

The not so good:
1. Not a lot of room for heighth adjustment in the sump. (The wholes for the floats are fairly wide apart and I found it difficult to find a set of holes for both switches to work right with my sumps.)

2. The switch itself is sensitive to EMF fields. So, be careful if placing it near any type of Metal Halide balasts, or other high power electrical equipment. (I found this out from the very responsive emails from Autotopoff.com).

3. I couldn't find a phone number for them for support, but they respond well to emails!

4. I would highly reccomend the dual float switch, redundancy is key and it's not that much more expensive!
 
I used one very briefly as a temporary setup. It worked flawlessly! I used the kit they sell. Since Im using a controller now, I had 4 custom floats made by them that I use. I dont think I will ever look at another company.
 
I have used them for over 5 years. They are a great company with great products. Currently have an ATO float, Display tank overflow shut-off float and a float in my skimmer cup to shut off skimmer pump when the cup gets full.
 
I use two float valves and a solenoid to fill up my RODI container which then gravity feeds a mechanical float valve in my sump. The bottom valve was occasionally getting stuck in the up position so my container would empty and would never refill. There was just a small burr on the shaft. I cleaned it up with a knife and haven't had problems since.

I'm ready to buy a few more switches to detect high water and low water levels in my system to set off alarms and email alerts before my floor gets wet.
 
Been using the double float switch and selenoid from them for over a year. Great product and had great service. The first switch, the one thats in the water, has never even been cleaned and it hasnt ever failed to the backup.
