Unsupervised Top Off System

[Bryan]

My current top off system consist of a 5 gallon bucket sitting on my enclosed balconey with nylon tubing running to the tank sump to a kent float valve. Works fine, except during the summer I have to fill the bucket every 2-3 days and I have to rely on friends or relatives to monitor during any extended holidays. Plus it's an inconvenience to constantly fill the bucket.

I would like to automate the system and was thinking of the following.

My water filtration consists of strictly DI filtration. Any reaon why I can't connect a needle/saddle valve under the kitchen sink, run the nylon tubing through a wall and out to the enclosed balconey to my DI filter which will empty into the bucket.

Under the sink I will incorporate a solenoid valve after the saddle valve(all kinds of solenoid valves at mcmaster.com for as low as $20.00) connected to a timer. Have the timer run a set period during the day, it wouldn't matter if it overfills the bucket as it's on the balconey anyways (drain Hole in the floor). The nylon tubing would only be under low pressure, just enough flow through the saddle valve to cause the required amount of flow through the DI filter.

I guess if I really wanted to do it right and avoid the overflow problem I could add a low and high float switch to the bucket so the solenoid kicks on and off at preset levels.

Any suggestions or comments.
