FC and CYA - Justifying the increased cost of Liquid Chlorine

..after the heater, yeah?

Oh right, there is plenty of space on the lower horizontal that's after the heater. I'll do that! Thanks.

Just ordered my TF Pro Salt.

Thank you for the information on the heater bypass. I see the value in the bypass, but I am not looking to invest in a lot of changes beyond the purchase of the SWG unless it's absolutely necessary, or if I will somehow recoup the cost in the next few years. I am in a temporary rental home (3-4 years) having been displaced by the California wild fires earlier this year. I got the SWG because I was/am convinced that it will pay for itself in liquid chlorine and time/hassle savings.

Do you think the SWG and flow switch will work on the 60 degree incline? PoolStored, you seemed to think the cell would be fine but maybe not the flow switch. Would there be an issue with installing the flow switch on the relatively horizontal pipe leading into the heater? Just a thought.

One somewhat related question...

Now that I'm converting to a SWG I understand that I will need to raise my CYA. It is currently at 50. This is admittedly a Leslies measurement corroborated by test strips, but I don't have my test kit yet. If I do indeed need to raise the CYA, would using the pucks I purchased before finding TFP be an ok way to do that. I now know that stabilized chlorine is no good for regular use, but I do have a big bucket of pucks sitting around.

Thanks.

P.S. I have plenty of fodder for my PoolStored entry, which I will post after I have installed the SWG and my pool is running smoothly - fingers crossed!

Chances are you will recoup the cost of a heater bypass in electric saving over a couple of years. The additional parts are a 3-way Jandy valve, a Jandy check valve a couple PVC fittings and a little bit of PVC pipe - maybe $200-$300 in materials.

And if you are installing a SWG, you are already cutting pipe and plumbing that in.

I would consider putting both the SWG and flow switch horizontal or vertical - easy enough to do away with that 45° section of pipe. Adding a 90 or two will not affect your plumbing efficiency.

Wait until you get your test kit and get the SWG installed before raising CYA.
You will also need to measure the present salt content before adding any additional salt.
