Hi I'm looking for some kind of fixture I can use to add corrosion inhibitor to the radiant side of my Geo thermal/radiant system. I have had to replace two pressure tanks in 5 years due to pinholing. I started using Sentinel X-100 corrosion inhibitor and it seems to be helping. The problem is how to add it to the loop on the radiant side. I am currently adding the whole quart to a garden hose and blasting it into the system with water pressure. It works but is messy and its hard to tell when its all in. Does anyone know of a fixture such as a bowl type container similar to a carbon filter bowl that I could just pour the Sentinel x-100 into and open the in and out valves and flush it into the system? Then I could bypass the bowl when not in use. Sentinel makes a syringe injection set-up but its intended for small amounts and its kinda dodgey. Any suggestions are welcome!
