Is CLR safe to use in 1/2" copper?

[joe shedler]

Hi guys,

Im out of town, in a house about 40 years old. I have a sandpoint well at 18', a run of about 30'-40' to the house a pump inside that fills a pressure tank (about 5gal I think). I have poor pressure at the faucets, tub, and shower, but full bore at a tap thats about 6" from the pressure tank. This leads me to belive I have hard water build up in my pipes (yes I do have hard water here )
I was thinking the cost to replace my pipes would not be cheap, including drywall repairs, and a tub surround that might have to come out in the replacement. So I wondered if I could fill the pipes with CLR and let that try to remove some of the hard water build up and save a bunch of money.
Is there a reason to not do this? As in would it harm any of the pipes, or faucets ect. or would it simply not work? Here is a pic I made showing how I was planning on getting the CLR into my lines.

I would need to add the shut off valve, and tap in that picture, but I was thinking having the shut off valve so close to the pump would mean I wouldn;t even lose my prime, and the pump should draw the CLR in through the hose.

Thanks to anyone who wants to reply, your time is appreciated.

I wouldn't do i . Check your screens and flow controls. Also remove a supply stop and have a look. Scale likes to build up right at the valve, you can also inspect the pipe at this time. Hot is usually worse. If you have dielectric unions on the water heater look there too.

Consider getting a softener. In addition to other advantages, it will stop new accumulation of minerals, and will slowly dissolve away existing deposits.

A pressure gauge can quantify your pressure drops. You can screw a garden hose thread pressure gauge to a laundry tap or the drain for the water heater.

good advice above, pull an angle stop
