I wanted to share my experience with Marlig fix a leak. I live at Howard Beach, New York. I lost 2.5 cars to Hurricane Sandy. I was fortunate enough to have my home. However my hot tub was another story. I had my hot tub company out to see if my tub was worth saving. They made some repairs like changed manifolds and replaced some hoses. The repair was not to bad. When all was said and done I spent about $500 and my tub is running great, but I am losing about an inch of water everyday. The guys who fixed my spa said they can not find where this is coming from with out me putting a bunch of money into it. They did recommend I go online and find this product called Marlig Fix A Leak. I found this product at SpaAndPoolDepot.com. I called them to discuss what my chances were of fixing this leak. They were very honest and said its a crap shoot. It might and it might not it depends on where the leak is at. I asked if they had any personal experience with it and they said their service department uses it all the time for people who do not want to spend a bunch of money to repair it. They said it works about 85-90% of the time though. Well I bought it and I am happy to say I am no longer losing any water. So thanks for the opportunity to share my opinion.
