Warm spot on the floor in Poulsbo, WA

The likely causes here

A recirculation loop fault: on homes with a hot water recirculation pump, a loop running constantly can warm a floor without any leak. In Poulsbo that usually means cracked poly on Noll Road near Highway 305, and the ground, bay-side outwash that drains instantly, decides how far the water travels before you see it.

The second thing we rule in or out is radiant heat, if the home has it. A radiant floor zone that's stuck on. It's common enough on shared easement lines in the old core that we never skip it.

Finally, a hot line leaking under a crawlspace floor. A pinhole or failed fitting under the subfloor warms the boards above. Worth five minutes before anyone digs hardpan on Finn Hill and Viking Way.

What to check first

Up Finn Hill and Viking Way the hardpan surfaces water downhill of the break.

What you can check yourself on subdivision lots off Viking Avenue: do the meter test with everything closed. Don't open the floor at the warm spot before it's located. If you get that far, we'll pick it up from there with pressure gauges and isolation and acoustic leak sensor and.
