Well then, if I ever manage to get things dried out, I’ll expect to see you here with drywall tape and mud in hand
Sure that’ll be a payment of 10 leak sensors.
You know that there are centralized alternatives. By mounting a device (sensor + flow stop switch) on the main inlet water pipe. They typically sense both unexpected high flow but also very small leakage via pressure change detection.
Where I live (Sweden) the brand WaterFuse is one alternative, but I am sure there must be other alternatives closer to you.
We pay a lot for homeowners insurance which will cover the damage caused by leaks. I have a few sensors but I am not going to get crazy and put sensors all over.
That sucks. I recently moved out of a house that had a mold problem. It was awful. . . .
You might also try putting hydraulic cement in any cracks and where the wall meets the corner. Three+ coats of water proofing paint after proper prep might help too. If there are any big cracks visible outside you should seal those with that polysomething stuff. I got two wet areas of my basement very dry this way.
HD has rebate specials on all Behr paints. You can often get a $40 rebate on the 5 gallon buckets of Behr masonry water proofing paint.
I’m not so sure about that plastic on the interior wall. It’s unclear if it is more harmful than helpful.
I found this useful:
In my basement, I have 5 of these water sensors:
I hooked them to an Arduino Mega (You can get these cheaper, this is just one I found quickly on Amazon.)
with a thing shield
https://shop.smartthings.com/#!/products/smartthings-shield-arduino (Unfortunately, looks like they are sold out at the moment they always seem to be sold out…)
and used @ogiewon 's ST Anything libraries.
to communicate to the ST hub where I ran a multiplexer smart app to distribute them to 5 virtual moisture sensors
If you can get a wire to where you need to check for moisture, this is a very economical way to put a lot of them around.
$18 for the Arduino, $40 (I think) for the thing shield, and $8 for the sensors.
You could do 10 sensors for about $14 each. (or 20 for about $10 each…) If you can find the water sensors cheaper (probably could if you ordered directly from China), it could be even cheaper.
Unfortunately, the room that flooded is below grade, so unless I dig a monster trench, I won’t know about external cracks. I wouldn’t be surprised to have to do it in the very near future though.
I used the Behr masonry paint on the outside of the house (different project), and it didn’t last very long before it started to peel up.
Good reading in that link you provided. Thanks, I’ve bookmarked it!
Most of my basement is below grade too, but there are a couple feet above. I found a big crack in one spot. I think it was the biggest problem. I patched anything that looked funny on the inside with hydraulic cement. I hope it lasts.
That sucks. I’ve seen mixed reviews of the product. I have my fingers crossed. I cleaned the walls with a broom and wire brush. Washed them with Tide. Acid etched anything that looked like it might have seen some efflorescence. Then I hydraulic cement patched all over and all along the bottom edge. I followed it with two coats, waited, and found more pin holes that I got with a third. What a pain. If it doesn’t stay put, it’s not my fault.
Great. There are many great articles on the building science web site. Most of them just make me realize that my 116 year old house is hopeless. . . .
Don’t feel bad. My house is only 11 years old and it’s already hopeless. Not a chance that it’ll make it to 116 years old.
First, check gutters, grade, pipes.
Second, invest in leak sensors, they are cheap compared to the repair. Put them in low spots.
Third, utilize your insurance when that all fails, that’s what it’s for…
I’ve been lucky, no leaks, and over time I’ve put a sensor here/there, and now I feel reasonably comfortable. But you can’t cover everything.
I don’t have flood insurance. Up until about 2 year ago, it was included with my homeowners insurance. I didn’t add it after they gave notice of not being included.
I have 10 water sensors and one valve shut off. I could probably use a few more but it already saved me with a busted washer hose
In the northeast it’s covered under water damage, not flood insurance. I’m no expert, but I believe a “flood” is an event that the government makes official, and yes, requires an even higher level of insurance.
Heavy rains, even “torrential downpours”, unless officially considered a flood should be covered by insurance under water damage parts of policy and dont’ require a “flood”.
This is my opinion (somewhat educated) on the matter. If you have an agent, they would be a great next call.
Well, that makes perfect sense to me. I hope my insurance company feels the same way. If I can’t get this sorted myself, I may need to give them a call.
Flood is from a natural disaster not plumbing at least with most insurance.
A sensor in each bathroom under the sink and/or toilet, ( they are sensitive enough that you can usually get away with 1 in between the 2 ) 1 under washing machine, kitchen sink, dishwasher. It may seem expensive and excessive, but even a single $500 deductible for water damage or the time and materials to fix it yourself will cost you more than 6-8 $30 sensors. You can even toss in the LeakSmart valve on the main coming into the house and still be ahead of the game.
Yup I have allot of water sensors and a valve shut off. Washer line busted while at work and it shut off. I had little water on the floor which I cleaned up with a few towels. Imagine this happened at 12 something and I dont get home till 6. My whole downstairs would have been flooded and tens of thousands in damage.
Where was your sensor at?
I have one by the drain in the basement, it would eventually catch it… but…
Sitting on the floor in between the washer and dryer. I am going with it detected it almost instantly!
That is about where I have mine. Behind the washer under the loop in the hoses and the gas trap for the drain. The ones under the kitchen sinks are right below the loop from the sprayer hose. about 3-4 drips of water is all it takes to shut off all water in the house.
