[C320-list] Fragile water lines

[John Morrison]

If U R thinking of replacing the head stay away from Jabsco. The Head Mistress recommends the Raritan as the best manual head ever. I agree and I had published a MainSheet article on how to install it. The original head in my boat, a Jabsco, required an $80 service kit every other season. The Raritan has been service free since installation!

Calcium carbonate (found on seawater) and urine crystals are a natural combination that will produce this problem.  So, probably not malicious, just poor (or no) maintenance.
