My SIB is on it's trailer in storage at present. After 5 weeks I went to check on it & found it half deflated. A friend of mine who is a marine engineer said all inflatables lose air & need to be pumped up. Another friend of mine said it is a problem with dirty valves & they need cleaning, it should not lose air. The boat is only 3 years old & has spent most of it's life deflated. Could this be the problem & has anyone else come across this?
If it deflated it is an air leak plain and simple. Pump it up to operating pressure and with either a garden sprayer or spray bottle filled with a mixture of dish washing liquid and water, start going to town. I would recommend starting at the valves, then work your way around. If you find nothing on top, flip it over and check the bottom. It may take a few minutes for the bubbles to appear. If you find a leak it might be prudent to continue the search.
Its likely it could be the temperature change, but the easy way to check is use soapy water on a paint brush around all the seams and valves and check for bubbles make sure your boat is fully inflated before you do this.
i had the same problem but thankfully mine was temprerature change
hope this helps
Temperature - common in this season (unless you're in SoCal ).
It means that your tubes were not hard enough beforehand too (for efficient use). Pump 'em up and watch 'em for a few days. Be aware that when the temp rises, the reverse happens. If you have no pressure relief valves then pop goes the weasel
May have been temperature, but the first time it deflated, was by a significate amount. Think it may have been something to do with original inflation, too harsh on the valves causing bad seal!
