Container house 20ft leaking water inside somehow

Anyone on here have a 20ft container house?  mine is getting water inside on subfloor, have already put new floor down, thought i fixed issue, but i believe it could be threshold at door, anyone have any ideas

You can use Ritt dye to figure out where leaks originate.  Buy three or four different colors and start by applying at lowest possible leak point.  If the leaky water is colored, there is a leak there.  If not, move to the next highest possibility and reapply that color of dye.  If you see the dye in the leaky water now, Note that that;s a leak point.  Then use a DIFFEREN dye for the next possible problem upstream (higher). Continue until all possibilitiesare covered.  I used this method to deal with leaks on 100 year old buildings I owned in Philadephia.

Good luck.

We had a s8m8oar problem where we used food coloring to find a leak.

Are you the person who did the finishing or dis you hire/buy the unit in question?

Are there water lines in that are or do you feel the water is coming from the outside?

Before I retired I used to specialize in roof repairs.  I observed 2 cases where condensation appeared as leaks.
 One case showed as water rolling down the walls. Very unusual but distinct.
 A second one collected on the metal frames  of skylights, light fixtures, etc in the bedroom ceilings.
The change in season temperature could be the culprit.
 I always wondered how these containers could avoid condensation problems.  
Seems like only a well insulated, sealed barrier would prevent condensation on the inside.
Your normal activities are going to generated warm moisture, and when it meets cold metal, will condensate instantly.
And based on what I saw, it can seem like a surprisingly large amount.

Water leaks can be difficult to trace but water does typically follow gravity. Is your first thought a door threshold because the water presents in front of the door? If yes, then chances are good that the leak is associated with the doorway at some point. It may not be at the threshold though. It could be anywhere around the perimeter of the door. Doors and windows are basically holes in the building envelope that need to be sealed all the way around the penetration. The water could be coming in along any point and traveling down the door framing until it finds a way into the house.

Here is my method for finding a leak in vertical walls. Get a water hose with a steady, but gentle flow. Start applying water to the exterior side of the house directly opposite of where you see water on the inside. Give it maybe 5-10 minutes and see if water appears inside. if you see the water inside, you are soaking the point of entry. If not, move the hose up and repeat until you start seeing water appear inside. If you are checking a door, check the bottom/threshold first. Then check one edge/side of the opening and then the other before checking the top/lintel area.

Webelieve the door may be the problem because its kinda near the door,  and im had issues with door, I don't think theres a door sill installed also, also when it rains, water sits on the black strip that sits under door , however we haved caulked everything

i was thinking the water could be getting in the screw holes where the adjustments for threshold possibly

I built a container home, biggest problem is condensation.  I use a house size dehumidifier and run it constantly except in summer when I leave a window Cracked open. Your breathing leaves water vapor, which then condenses inside the metal. It doesn't matter if you have good insulation or not. It is more helpful if you built a heavy outside sheath and this will help lower ao.e condensation.

Just a thought, you did not mention how you are heating the inside of your container. Propane heaters i.e. Mr Buddy etc, will add a lot of moisture to your interior space.

mini split, but heat hasnt been on any yet

If you sealed around the door, the screw holes shouldn’t be the problem. If the water is pooling at the door, it could have come from a high point and ended up there. I suggest using liquid food coloring and not dye. The dye will be hard to remove, but food coloring should clean up easily. I do like the idea of going uphill by intervals and pouring the color in. I also like the idea of using different colors as you progress upwards. Good luck!

Theas is right about the dye being difficult to remove.  I never worried about it because I would always have to do wall or surface repair after the leaks were fixed anyway.   It all depends on hpw permeable the surface is and how quickly ou can get to cleaning it up.
