Legal Advice or plumbing advice?

OK. I purchased my house in 2006 (Maryland) AS IS. I have been working on updating the home and appliances since then andI purchased a home warranty. Last year, my daughter's bathroom had a leak. I called the home warranty company and they sent out a plumber from a local plumbing company. The plumbers came (2 of them) and came up with my daughter's tub needed to be caulked. I knew that was not the issue since the tub was not in use at the time of the leak. So they left and informed the warranty company. Two weeks later my home flooded because of the same issue in my daughter's bathroom and again the tub was not in use. So I called the warranty place and they call the same plumbers out. This time they said she had a fracture in the bowl and replaced the toilet. This weekend, my home flooded again 10 times worst than before. I called a local plumbing company who came out and told me the toilet (which was a $40 Mancessa toilet was sub par and had a crack in the toilet tank, which caused the flood. I paid $700 for the plumber to install a Gerber Viper. My home, furniture and hard wood floors are all ruined (3 levels). I called the insurance company who sent out a team to manage the water damage. Each day we are conducting meter readings and my home is still wet. The water damage compaby said they will need to pull up all the flooring, My insurance company told me the $700 spent for a new toilet does not reduce my $1000 deductible. My insurance company cleaned the 1st flood and I made them aware of what the plumber I haired wrote on the invoice regarding why the flood happened. I called the home warranty compnay who told me to contact the plumbers who is licensed with their own insurance. The woman who answere the phone at the plumbing company contracted by the warranty company immediatley took offense and was very rude. She would not transfer the call to anyone else for me to talk to. So far, I have not been able to pay my mortgage (1st time late) dealing with this issue. I am missing time from work coming out every day for moisture readings. vistis from the adjuster, and constant calls to the warranty place. I have missed a lot of time and gas dealing with this problem not to mention the thousands of dollars of damage, late fees and stress What should my next steps be? Who is responsible (plumbers or warranty company? What type of attorney do I need? Any other advice you can give? Thanks
