This is kind of long but I really need a quick answer please.
Moved into home with old pool and equipment. We filled in the very bottom of the attatched spa with sand, gravel and cement so now it is a little wading area for the kids. Plastering guys said we did a great job and then they got to work. To save money on labor, husband labeled and cut the equipment pipes (at about 1.5 feet off the ground) so everything was clean for the pool plumbing guy (diff. from plastering co.) to put in our new equipment. After being asked once by me and once by plaster guy to pressure test our pipes, he says no, not needed. After re-plastering and filling up our pool Saturday night, turned on pump and filter and within 1 minute a big underwater pop and the middle of our spa cracked where we filled it in. Come to find out the guy plumbed the filter and pump backwards so the skimmer is pushing out water, not bringing it in...therefore, forcing air/water through the drain in the spa causing it to crack the cement at top. Called the guy, he is going to come fix the plumbing but no apology cause he says my husband had labeled the pipes and that is what he went by...so basically it's our fault. Shouldn't he have pressure tested the pipes or dumped water down them to make sure where the pipes led to? I told him about our spa and he just said, "oh that is no good."
Do I have all rights to say it was his fault the spa cracked and he needs to take responsibility?
Thank you!
