T&T: Pesky leak

[Blake]

The best "snoop" for this is Ivory clear dish soap.  It is unaffected by
most chemicals and bubbles much faster and better than anything else I have
ever used.  Snoop is the trade name for a similar product which you are
supposed to use for this purpose.  It is useless in most cases.  Also by
simply blowing high pressure air, from a compressor on the leaking area can
work and possibly save you a lot of tape and more importantly, work.

Leaks come from the strangest places and water often travels several feet 
before it drips on your face. A good suspect is the screws or bolts holding
on 
deck trim or fittings. If the bedding fails, water may wick down along the
screw 
and enter the interior.

Here is a technique we used to find pesky deck leaks during our sailing
days. 
Cover all vents and openings with a layer of polyethelyne plastic held down 
with duct tape. Shut and seal all portholes and hatches. Get an electric
leaf 
blower or a vacuum cleaner that blows air and duct tape its outlet to a port
or 
vent. Your object is to slightly pressurize the air inside the hull. A 
fraction of a pound per sq. inch air pressure is enough.

Now swab the suspected leak area with soapy water. Better yet is the bubble 
pipe solution sold in toy stores. You can buy a quart of the stuff for about
a 
dollar in WalMart or Toys R Us. If you have identified the leak area 
correctly, you will see bubbles arising from the location of the leak. Be
sure to check 
around all the deck hardware, stantions, cleats, etc. When you find the
leak, 
make the suitable repair.

It worked for us.

P.S. If all else fails, rig a small bucket under the leak to catch the
drips.
