Unreliable company. They also do well water tests. Took our water AND $125, NEVER GOT BACK TO US THAT OUR WATER HAD FAILED - HAD BACTERIA IN IT!!!! When we finally tracked them down 6 weeks later and all they said was "Sorry", we lost your info- although our name and address were right on the bill they sent!!!! and "we can chlorinate for $325". Thanks for nothing! Both my husband and myself were having some health issues from this! Never offered to refund us - nothing. COMPLETELY IRRESPONSIBLE!!!
