Occasional leak under laundry cabinet
Had a new washer/dryer combo installed with a new laundry tub by a "professional plumber" a few years ago.Every now and then I have a leak under the cabinet.No rhyme or reason why.I have disassembled and reconnected the strainer and pvc piping.Everything is done correctly as far I can see.I can run hot water for 5-6 minutes and surprise surprise no leaks seen or on my paper towel.I am flabbergasted and perplexed as to why.Any ideas or tips?
Thanks to all who can suggest a solution and for your time and concern

Where is the leak coming from? Pictures of your plumbing would help since we have no idea what you have.

Most likely it's the drain piping slightly off plumb. You might want to loosen the P trap and related fittings and then relieve any possible strain that might be present. Then re-align and hand tighten (firm, a wrench should not be needed) all slip nuts.

Thanks to all who replied.The cabinet is the under laundry tub itself.
I will check the plumb for 1/4 inch per foot.
Like I stated it was done by a "professional".

I agree that it's likely the pvc trap. As they heat/cool, they sometimes have random dripping issues. It may become worse when the washing machine dumps all the water into the laundry tub. Since it's plastic too, it can bend a bit due to the weight of the water, and cause a drip.
Best solution is to replace the plastic washer that connect the trap to the tub, and the 2 washers that are on the trap. I've run into traps that just won't seal properly until the washers were replaced, even though there didn't appear to be any defect on the washers.
