VERY slow air mattress leak

Put a gallon of warm water in a pump sprayer and add about a quarter cup of dishwashing detergent. Slosh it around until it's mixed. Lay the mattress out in the yard and inflate it until it's very firm, hose it down liberally and wait. If you don't see any bubbles growing after 15 minutes turn it over and repeat.

You can get a pre-made mixture at the dime store. Kids use it for blowing bubbles at parties...

COLEMAN--You're probably right.

I did this.. a water bed... but anyway

over fill with AIR... BIG Time...

next get the fluid for checking Gas leaks in pipes.. Home Depot...
much better than soap and water....

and have someone LAY on the air bag ( Full Weight )... while checking for leak

for my water bed... King Size took almost 3 hours.. to find the small pin hole

Sounds like your resolution is buying a new mattress.

I have a VERY slow air mattress leak. Barely there but, after a few hours sleeping on it,it loses 1/2 the air. If just filled and left alone, it takes a day and a half to lose half the air and never loses much more.
Did the soapy water routine with no visible leak.
Any ideas where it could be or is it a lost cause?

Are you sure you've closed the valve completely since the soapy water test failed? Might be time to re-read the mattress's instructions/manual.

I was thinking a pool. Lay on it for an hour then try the other side. Has to be found.

Could well be a check valve either in the hoses or at the air pump it's self.

PR--I thought of that. Would be a real pain in the butt and still probably wouldn't see it.
