OK really didn’t see topic to post this in, but I did fix it myself.

Was smelling faint smell of sewer gas in front bath room that we rarely use, which was slowly getting worse? Clue?

First I thought it maybe the Studor vent under sink. So crawled down and look under. Nope no studor valve vent, connected to plumbing vent system. My next thought the toilet? Then light bulb came on and I bent over the bath tub and smell was stronger.

I asked my wife when last time we had tube water running? Same as me couldn’t remember. So my fix was run some water to fill up tube drain trap? Fixed the problem. I guess water evaporated enough to lets gas escape up drain.

How long did this take? Guessing 4 months or more? We also had some strong winds few weeks ago wondering if that may have siphoned some water out of traps from roof vent tubes?

Anyway I will be running water in tub every few weeks.

Common issue back home. Other bathrooms were no longer used after children grew up, so every couple of months septic tank smell during summer. AC unit would draw it up. Capped off their tubs and sinks with stopper in drains and overflow vents. Debated about filling with cooking oil.

Good point for down here. Rarely guest bathroom is used.

Personally, I would never cap off a drain or an overflow. You don't know when a faucet will start leaking and cause a flood.

I run water everywhere once a week.

Once a week someone uses the front two showers, and sinks. We, as does our 3 kids and one grand, have heightened sensitive smell, bonus for all our OR years.

Without running water every week, slight odor in front bathrooms here. Not noticeable with guests, for us week 3 it’s overpowering.

Up north we still have septic so never smell from not running water, technically a closed system.

We get that smell from the washing machine. I opened up bottom up and cleaned the filter system, and that worked for a few weeks but came back. Now we run a machine cleaning cycle every 2-3 weeks because it will come back.

Leave the door open so it can breath.

Is that front loader washer? If so look behind door seal fro scum would be my guess? If top loader and old I suspect inner tube scummed up especially if over use softeners? The drain line tube has trap if you get nose close to it see if smell coming from that? I remember finding utube video’s on how to clean top loader inner drum when it smells using some type cleaner., might try search? On older models I use to take drum out and clean behind outer drum holes. IMO the new stuff junk and will never last as long as old units pre 2000s.
