The bottle test showed that if a surface is cold enough the humidity in the air will soak it. (And if this happens without a warm patch to dry it out = the mould that is present every where can take root.) |
i have no idea what mirror and bottle you are talking about as i dont remember running those in my tests

this seems to support that blowing hot air into the crawl with my fan may help get rid of my remaining water down there by increasing the temp in there. Though I still wonder why it's not draining because i'm 100% sure it does drain out over time (per your post it's not evaporating). and since all they installed outside my house was a 'hole' and a ton of stones, that should in theory make it empty faster! But even after it's dry, i hope the RH goes down or i'll be upset
and yes we know the floor temp in june but i have no idea what it is in january so cant wait to find out what RH and temps are down there then. At this rate i think until i have 4 seasonal numbers, i cant really take any steps as it would be pointless. But if in winter there is no water in there and the RH is 'reasonable' then it's clear i can clean the tons of mold then put a barrier down there to help the water droplets stay out.

i dont understand the metaphor. The dehumid. pumps out vast quantities of heat so it will actually heat up the crawl if i put it down there. So i dont get what freezing space you are talking about. Unless you just mean the air pumping through the coils? Speaking of which, i think it's safe to say even with one screen in there is zero air flow into that crawl (ie 50% RH outside and still 95% in the crawl) so i'm not even worried about sealing up my screen that good once the dehumid. is in place and running.

You can't stop it, you can slow it down - you can make life easier on your dehumidifier so it doesn't have to work so hard. |
from your quote, it sounds like my foundation blocks are likely saturated with water and the water comes thru my walls and into the rooms. Now that the crawl is waterproofed, they should dry out and thus the living space start to dry out?
sound more likely than anything else i've heard. Plus would explain the high bathroom RH since the downspout known to be previously be pouring water against that side of the house is right near the bathroom.
Hmm we may have solved the mystery.
