Good afternoon, I hope you are doing great. My name is***** would be happy to answer this for you.

If you have had to replace the pump 3 times so far then it sounds like they are not actually repairing the original fault that is leading to the pump failure. I would suggest having the lines and manifold tested for leakage. If there are any leaks in the system it will cause the pump to be overworked, which then leads to premature failure
