Hello. I have read many postings about this but am still not sure about this. We just finish building the pool last Friday. We have a Hayward Heatpro with Titanium Heat Exchanger. When I went to the pool supply store to get my water tested and told them about my setup he said i needed a zinc anode. The one he sold me (which has not been installed yet) he said to drill a small hole on the intake of the heatpump and clamp it on it ... sort of like a flowmeter... this one looks like a flowmeter. It puts the zinc in the flow of the water. There is also a connection to the bonding of the pool. Do I really need this or is it a bunch of you know what. The heat pump cost 3200 installed, and the zinc anode 109. he said it is a small price to pay to slow down corrosion.
I would agree with him... only if the science is true? I spoke to the pool installer, he said the only other metal touching the pool other than the heatpump is the aluminum coping (no constant water touch there) and the stainless steel ladders. He said he would be happy to come by tomorrow to install it for me for free if I really wanted it. But do I need it?
