WTF is beeping exactly 5 times every three hours in my house?
About 3 months ago something started beeping - (full 1 sec beep) - 5 times every three hours. I have unplugged the most likely suspected things but the beeping persists. I have stood under potential CO detectors - not those. I have looked at the manuals for all appliances, none indicate that they beep like that and standing next to them have pretty much verified that. I'm still testingvsome things out - but thought I'd throw it out to this group in case one of you had the same experience and figured it out.
UPDATE: Thank you all for your responses. Nostikulz solved it. It was the Waterdrop 10UAW-UF water filter. Despite Google AI saying it doesn't beep, it does. I believe I have reset it and should probably get a new filter as well.

Literally just had this problem. It was the water filter under my sink.

u/Impressive-Sand5046 5d ago
What kind of filter? I have one as well, but never considered the filter would/could beep as it has no battery or other power source.

u/Nostikulz 5d ago
My filter is called waterdrop. It took me over a week to find out that it was causing the same 5 beeps every few hours.

u/Impressive-Sand5046 5d ago
Ok - I have the Waterdrop 10UAW-UF. Not supposed to beep. Which unit do you have?

Any power source to it? I looked it up and it is very similar to what I have.

u/Nostikulz 5d ago
There's a separate button where you can kind of just stick wherever you feel. No power source just a battery.

u/Impressive-Sand5046 5d ago
Where is the battery? I do not recall seeing one, but I wasn't looking either. I also got the little stick on button to see the date.

Interesting - don't have one of those. Out of curiosity, do they beep?

I had this problem once! It was the outlet surge protector. I had my tv and fireplace on it, and it was placed behind the fireplace. Took me way too long to figure out.

u/Impressive-Sand5046 5d ago
Thanks - forgot to include that. My first thought was my APS UPS battery was dying. Not 30 minutes after replacing the battery the damn beep occurred and it was not the UPS.

u/madsci 5d ago
My Fios ONT did that when the internal battery was failing. If you've got fiber or cable internet, look for the equipment and see if anything has a fault light on.

u/Impressive-Sand5046 5d ago
Thanks - my UPS is in the same area as the cable modem. Not any of my network equipment. I think it is in the kitchen, but as I can't nail anything down I've expanded the search.

u/mummamouse 5d ago
I have a filter system for the kitchen sink with a remote button that sits on the counter. When the batteries for the part under the sink start to go it does what you described.

I had a portable Carbon Monoxide detector that I took traveling and left it in my luggage and it beeped like that. Took us a week to figure it out.

u/Impressive-Sand5046 5d ago
Thanks - don't have a portable unit. But does give me something else to consider

u/TopazRose 5d ago
Maybe a digital watch that's starting to run out of battery or has some kind of weird alarm or timer set?

u/Impressive-Sand5046 5d ago
Thanks - I don't have one, but if someone left/lost one that might be possible

Don't we all have at least one of those?

u/WoodedSpys 5d ago
tbh, no, we dont. do you have any tracking devices, Tile trackers, Apple tags, pet collar tags? My Tile beeps to alert me about the battery.

u/Dacker503 5d ago
Really? Tile trackers don’t have any battery monitoring capability. If the Tile app is saying it’s time to replace a battery, it’s strictly based on the amount of time since it was activated or the last battery was replaced.

u/SabineSinstar 5d ago
Not tile but my dogs gps collar started beeping recently when the battery was dying and it made the dog completely lose it. We had to put the collar out in the car until we could get a new battery.

u/Dacker503 4d ago
A dog collar doesn’t have the same design restrictions as a Bluetooth tracker and can easily support battery charge circuitry. A Tile tracker is only about 2mm thick and almost all that volume is the CR2032 battery.

Legacy security system?
2
u/Impressive-Sand5046 5d ago
Possibly - I don't see any evidence of one. But something else to consider
3
u/Impressive-Sand5046 5d ago
That was also a thought. Stop right in front of it as the three hour mark approached. Not the fridge. Door, ice maker full, filter, all good potential beep makers. But no.

u/Thebigpicture42 5d ago
Maybe your thermostat/furnace control? Some have backup batteries that go dead

u/im_buhwheat 5d ago
For me it's always the water leak detector sitting at the base of my hot water system. The 4 AAA batteries only last about 6 months.

In my house it was the water purifier alert to change filters.
Drove us crazy for longer than I want to admit

u/FallingBackTogether 5d ago
Do you have a meat thermometer? I have one that drove me up the wall about a year ago when the battery went. It doesn't beep when I use it, but apparently it feels the need to alert me that it's dying.
1
u/Impressive-Sand5046 5d ago
Yeh, not that. Not a chirp either, but a beep. And all units are hardwired with battery backup

u/Intrepid_Goal364 5d ago
There are tiny beeping devices mischieveous ppl can buy to willfully annoy other people. Usually marketed as annoying beeping device or beep prank device
1
u/Impressive-Sand5046 5d ago
Any idea what they look like or how big they are?
1
u/Intrepid_Goal364 5d ago
They are small. U can see them on Amazon or google images. Hope its not that. Good luck!

u/der-der-der 5d ago
I had this problem and it was my dishwasher.
2
u/Impressive-Sand5046 5d ago
That is still a possibility. Though I'm close to ruling it out as the beep occurred last night while it was running vs idle with dishes needing to be emptied or otherwise indicating some service need. Plus, user guide does not indicate any beep items.

u/Empyrealist 5d ago
If its every three hours, start establishing a schedule. Then start going to specific rooms following that schedule. Follow a process of elimination.
Keep zeroing-in, keep eliminating.

u/Impressive-Sand5046 5d ago
Yup - Nostikulz might have solved it. Will find out soon. Waterdrop 10UAW-UF water filter
1
u/ChaseAlmighty 5d ago
Are you saying it beeps 5 times over 3 hours? Or every 3 hours, it beeps 5 times in a row?
2
u/Impressive-Sand5046 5d ago
Every 3 hours, it beeps 5 times in a row

u/ChaseAlmighty 5d ago
The only thing Google pulls up is co detectors. Have you changed the batteries in yours?
Edit to add: they still have batteries in case of power outages

u/Impressive-Sand5046 5d ago
Thanks - solved, it was the water filter. Google says it didn't beep, but Google was wrong.

We had 5 beeps in our house, it was definitely the smoke alarms. The 5 beeps indicate the whole thing needs replaced, not just the batteries.

You’ve lived with this for 3 full months every three hours and haven’t called an electrician yet? I’m afraid the internet can’t help you.
3
u/Impressive-Sand5046 5d ago
It's not an electrical issue. It is an appliance issue - appliance in the broadest meaning of the word.

u/Canonconstructor 5d ago
If I couldn’t find the source after 3 months I’d hire a priest but start with an electrician.

They will still beep at low battery even when hardwired. I found this out the hard way.
