Tell me your strategy on dripping the faucets?

When do you turn them off?

I’m on a water well and drip all my faucets because no water bill.

I drip my tankless that’s on the outside of the house but not the tank that’s in the attic. I’ll also do a cold in another part of the house.

For the record, I measured the temperature of water coming out of the tap this morning in a remote upstairs above the garage bathroom and it was 52 degrees for the cold and 51 for the hot. The cold warmed up a few degrees to a more normal temperature, but you could easily tell it had gotten chillier over night
Also, you can see that the hot doesn't stay any warmer than the cold, thus I'd drip both hot and cold.
But, if mine was "only" 51 degrees at the worst (Air temp this morning was 18) I assume I don't need to worry too deeply about dripping, when I did not drip water last night.

Dumb question, what’d you use to measure the temp?

I’m no scientist, but I’m going to guess he used a thermometer.

ETA my example

People over think this. Just drip one of them. If it's on an exterior wall have a little heavier drip and open the cabinet doors for extra measures. It's not rocket science.

What about outdoor faucets? Do y’all wrap them with towels and plastic bag, or drip them?

I have a pier and beam home...water heater on one side with 1 hot water line and 1 cold water line running the entire length of the house. They are insulated but if you only drip the cold you will get no movement in the other...aside from being there and turning it on and off.

It's good to overthink things sometimes.

People under think this. Most people have no clue how their house is plumbed, and therfore cannot make an educated guess on what the best way to protect it from freezing might be. People making blanket statements like this don't understand it any better than anyone else.

My company does water mitigation. Most of the jobs are from busted pipes. 90% of the busted pipes are someone that just didn't leave the faucet dripping. Can't recall a single time we've done a job in 7 years where the homeowner said they had the water dripping where the burst was. I could plumb an entire house if I needed to, not understanding it certainly isn't an issue with me. There was the same thread on the OT and there were 100 different answers on what to do. It's not that hard. It's Louisiana, we get a few freezing days a year, if you use a little common sense in those few days you're not going to have any issues.

I think he was taking issue with you saying you only need to drip either the hot or cold....or seemed like you were saying that.


When I plumbed my house I ran some hot lines in the shortest route possible to avoid wait times. For the cold I just went the most convenient route. Dripping only the hot or cold would not help the other line at all.

To leave no doubt, you must drip both hot and cold at the some faucet. One is better than none but dripping both leaves no doubt.

I learned the hard way. Didn't drip hot one year and woke up to cold water, but no hot. I think it froze in the attic near the tankless.

Depends.

Drip hot water furthest away from the tank. Will keep the largest amount of water flowing through pipes.

Drip any along external walls (hot and cold).

Figure out how your piping is run and come up with a plan from there.

My main comes in on one side of the house, runs across to the other to the hot water tank. I drip the hot on the opposite side of the house from the tank and it keeps all the headers flowing. I also know where all the drops are to the bathrooms and drip the hot and cold where I know they are exposed to external walls. Also run the washing machine on warm (so it runs hot and cold), empty the ice tray (so it cycles the cold), and run the dishwasher on delayed cycle at night (runs the hot water through the night). May be a little overkill, but haven't had an issue since.

Eh, and I know it's about over at this point but plumbers recommend to drip hot & cold.
