Water In Floor Vents After Heavy Rain

Possible causes and suggestions to alleviate problem appreciated.

Water in floor vents after heavy rain.

Anyone who suffers from subsurface water that is invading any part of a house can stop it in almost all cases by capturing the water outdoors and then redirecting this water to the lowest part of the lot. If there is still a large amount of water in the vents and going on the assumption that the water is from the gutter flood event they need to be pumped out. It s no wonder the vents filled back up after you pumped them out. In this room the two floor vents fill with water when we get rain.

One was 5700 the other was 4500. What is the best way to fix this situation. One vent has completely corroded on the bottom then and the ground water seeps in and fills that whole section of vents. If it is only in one vent you need to first eliminate the possibility of an interior source such as over watering a house plant a leaking aquarium or someone spilling water nearby.

Seller installed sump pump under outside deck but it s not draining all the water. Floor is on slab. How does water get into floor hvac vents during periods of heavy rain. I have been told to fill the vents with concrete or expanding foam and abandon them lift my furnace tap into the down flow and put a new vent in the ceiling in that room and even get.

The 5700 said they would pour cement through all the floor ducts throughout the house. Remove debris make sure your roof valleys are clear of debris re shingle valleys valleys may need to be reshingled with new ice and water shield put in place. You can get a cheap pump connect a garden hose to it and direct the water outside. If you see water in any vent you should examine all of the other boots and ducts for water.

I had water in my floor vents after a heavy rain last summer. If the problem is not too serious you can remove the water with cloths and a wet shop vac making sure you do all areas that you can get to. During heavy rain or flooding water can get into the ducts causing damage to the ducts and the furnace. Have gotten to estimates on running ducts through ceiling.

The water and any accompanying mud must be removed immediately to avoid problems.
