Hi there! I was searching and got to know to know this thread! Sorry for replying so late. But I think you need to contact a good technician to find out the leak. It might be having some leak which causes the water drain completely. Few days back, a leak detected in my hot tub which causes the problem of water damage in the house. Water damage is just a headache to every homeowner and also needed repairing. So, my cousin told me that home insurance coverage covers water damage in the house and to consult a public adjuster Orlando for filing an insurance claim for the water damage.
