I am thinking of taking the plunge this year to an SWG. I've been BBB with liquid chlorine (jugs) for the past 4 or 5 years, but am looking at some extended vacations this year, so I am thinking the SWG will be much easier than finding a reliable person to test and dose my pool.
I really like the timer functioning built into my pump, but from what I have read so far on the subject, the only way to safely control an SWG is through the addition of an automation system or a load sensing switch (as the flow sensing can be unreliable).
I have no need for any actuated valves as I don't have any waterfall features or any type of heater (solar or otherwise). My pool robot runs off a light sensing timer that plugs into an outside outlet (like the kind you use for Christmas lights, runs for 4 hours every night after it senses darkness).
Basically it is a very simple setup and so I would like to keep the cost at a minimum. Any thoughts on what direction I should go with this? Which combo of SWG and automation/switch? I would be okay with a load sensing setup, but if it is only within $200 or so of an automation system, I would probably go with that for the sake of the simplicity of installing and reduced issues should any of the equipment require service under warranty.
