Tips of draining and re-filling my pool.

[andres1987]

My CYA and CH are insanely high so I'll be doing a draining and re-filling of my pool. I'm going to take advantage and scrub all the waterline tile as there is a lot of scaling. I bought De-scale it and a pumice stone and then finish it off with a good power wash. Going to take apart the DE filter and clean it as well. Should I go rent a pump from Home Depot to drain it, or will doing it through the waste function on my system be ok? What do I need to do after the pool fills up again?

My latest test results using the TFT test kit:

FC - 1.0
pH - 8.2
TA - 110
CH - 950
CYA - 80
CSI - 0.96

Specs on my pool - inground chlorine pool with spa ~12.5K gallons.
Equipment - All Pentair with automation, quad DE filter, 3.0 hp pump, air blower, 400k BTU heater.

Have you considered having your tile bead blasted? In my area, cost is around $4 per linear foot. They need to drain the pool down about a foot anyways. I'm sure they wouldn't mind draining more for the same cost. Just a thought.

Yes I did. I messaged a company out here that does that and they responded with an automated message saying it would be minimum $1300. My pool is about 99 LF so that price is ridiculous.

Add beer and Motrin to the shopping list. Sounds like you're going to need it.

It's always best to use a submersible pump as opposed to the pool pump to drain the pool. You don't want to risk running your pump dry. If you have a dedicated suction line running to a main drain, you may be able to pull it off with less risk. I would still stick real close to the pump just to make sure it doesn't run dry. If rising CH is going to be a constant battle for you, you might just want to buy a decent sub-pump.

Best of luck!

yup, already looked up a submersible pump to rent at home depot. I've just had the pool for 1.5 years, hoping rising CH and CYA won't be a constant issue.
