What To Do?

I’m getting fed up with our water pipes and kitchen faucets. The repair man and plumber that I asked to repair it several times have been scratching his head as well. He said that instead of continuously repairing it, we have to replace it already with a tougher pipes and quality faucet brand such as Kohler kitchen faucets. I told our owner of the house about our endless water pipe problem and he seems to be ignoring our requests. The husband said we should not be the one spending for each repairs since we have done our part already and the problem now has to be take care of by the owner. But as I’ve said he doesn’t seem to care. I don’t know what to do now ,sigh.
