Marine Watermaker Sales & Service in Florida

Marine Watermakers for Yachts Worldwide

Watermaker specialists install and service the reverse-osmosis desalination systems that turn seawater into fresh water aboard, freeing a yacht from dockside fills. Their work covers high-pressure pumps, RO membranes, pre-filters, energy-recovery and boost systems, controls, and the plumbing and product-water testing that go with them. Common problems include low water output, poor product-water quality (high salinity), high-pressure pump and seal failures, fouled or scaled membranes, and pre-filter neglect that ruins the expensive membranes downstream. Most watermaker failures trace back to maintenance: dirty pre-filters, improper pickling during layup, or running the unit in dirty harbor water. Good techs emphasize correct fresh-water flushing, pickling, and pre-filtration to protect the membranes, which are the costliest part to replace.

When hiring, look for factory training on your brand (Sea Recovery, Spectra, Schenker, Idromar), RO membrane and high-pressure pump experience, water-testing capability, and references for installs and rebuilds.

Frequently Asked Questions

Q: Why has my watermaker’s output dropped?
A: Often clogged pre-filters, fouled or scaled membranes, or a worn high-pressure pump. Low feed pressure or cold water also reduces output. Filters and pressures are checked first.

Q: My water tastes salty. What’s wrong?
A: High product salinity usually means a damaged or worn-out membrane or a bad seal letting feed water bypass. The product water is tested and membranes inspected.

Q: How do I protect the system when not in use?
A: Fresh-water flush after each use and pickle (chemically preserve) the membranes for longer layups. Proper pickling prevents biological fouling and membrane damage.
