Our endcaps on our 160 liter watermaker failed at about 180 hours
(almost 4 years). Your endcap failure sounds similar manner to ours.
The o-rings on the high pressure fittings ('salt water in' and the
'interconnect bobbin')on the endcaps failed and water eroded the
(white) nylon causing a leak. This was our only failure in less than
200 hours of operation. We bought replacement endcaps from
Dessalator. The replacements are black. We now have 284 hours on the
We have been getting between 130 and 200 TDS readings since the
replacement of the membranes which came from AirWaterIce. The longer
the system runs the less TDS.
We should note that we have a manual diverter valve and we discard the
first several minutes of product water until the TDS reading moves
below 200. We always check the TDS before we shut the system down and
usually have a reading of less than 140...in other words TDS does
improve the longer the system runs. A TDS reading from our fresh
water tank is usually about 135.

high pressure operation. You will recall I said that I said thatthey built
a two minute delay into the new board for commonality with the oldboard.
The TDS reading of the water produced was 340 ppm which is marvelousIt dumped
the water overboard as soon as it detected a problem with mymembranes and
activated the bad water LED.end cap,
this time at the hose connection end. Water had got pass the two1.5mm x 9mm
o-rings and eroded the nylon, creating a serious leak. This was my5th end
cap failure in just over 200 hours of operation! My end caps arewhite. Has
anyone else had a similar problem? Amel say that it is very rare! Idon't
