We have a home built in 2004 with a Manabloc that was installed on the original build. We have been living in the home since 2018 and I've never used the Manabloc valves. There is small RO system in the basement equipment room on an adjacent wall to the Manabloc that goes the length of the house and up to icemaker and a faucet on the kitchen sink approximately 40-50 away. Anyway, I need to change the filters and membrane in the RO system ( I know, should have been done already, but I'm leery of any plumbing as I don't have good luck) and am a little leery of actually using the Manabloc valves since it's obviously been 4 1/2 years since they "may or may not" have been used. The RO system has 5/8" PEX coming from the manifold into a brass reducer to 1/2 or 3/8" PEX into what looks like a John Guest reducer to go to the 1/4" poly that feeds the RO system. I have purchased a John Guest 1/4" shutoff to put into this line as well if needed for the filter changes.
All of that to simply confirm, better to shut off the main to do the filter swap or try and use the Manabloc?
Sorry for the terrible pic, but it's all I have at work at the moment.
