I've had my Tapmaster for 14 months or so without any issue. I've never heard of anything like you describe.

Have you asked Tapmaster about the hard water issue and your problems in general?

If you water is super hard, you don't have a house water softener? If you don't have one, I would guess you would see signs of hard water damage on appliances and other water-using items in your house. Do you?

Have you spoken with a plumber about this and your water?

I'm sorry you've had such bad luck!

I did email Tapmaster, regarding the hard water but have not heard back from them yet. I don't have a whole-house softener because I just haven't invested in it yet. We do get mineral deposits on our appliances, faucets, etc., but I just wipe it with vinegar. The Tapmaster has to be taken apart to run vinegar through it, I think. Thanks for your response.

Just bumping this up to see if anyone has any suggestions for me! Thanks.

I don't have hard water, fortunately, but thought that it did slow internal damage to appliances. I know that a whole house softener is expensive!

I'd be interested to know what you hear back from Tapmaster.

Sorry I can't offer help, but maybe this will bump you up for someone else who can help.

Thanks for trying to help. My husband opened it up and ran some vinegar through the tubes to break up the mineral deposits. It helped. But it's a pain in the neck to have to do that every eight months or so.
