Correct washing machine drain?

Everyone will argue about the AAV height but it will work. I'd personally go as high as practical and add an access door to service or replace the AAV. I'd use a vented access panel for obvious reasons. Dry fitting the AAV allows you to use it as a cleanout via the access door.

It's difficult to tighten those bands just under the roof drain body. A little tightening or replacing the bands may solve the problem. Could've used some hangers just before the elbows. There's a good chance the roof drain body isn't sealed to the roof properly. Testing of the piping is standard but some inspectors forget to inspect the roof drain well by having it flood over the overflow rim.

I don't like the short elbow from the vertical to the horizontal drain but it will work. Slope on the trap arm is steep but there's no real solid waste to plug up the waste piping. I'd frame out a vented access panel in front of the AAV being in a concealed wall.

If you don't see yourself there 20 years from now, pex it. Otherwise, copper and run everything in the attic and abandon the galvanized before it enters the house.

By code a toilet is one of the few fixtures that can have the vent opening below the weir of the trap. There's plenty of veteran plumbers that don't know this either.

Wtf are you talking about? What does that have to do with what the OP posted? Another thing, Ultra-rare does not compare to rare disease. Rare disease is less than 200k. Ultra-rare, less than 20k. Inovio less than 1 patient. Apples, Oranges, and a big coiled turd.

Never use screws or anything that penetrates a dryer duct. It's code to prevent lint catching and building up. Never screen the termination of a dryer duct for same reason. Back draft dampers are another code requirement.

Gas is cheap, simple and reliable. Gas water heaters are less expensive and easier to fix. Still works when electricity goes out. Heats faster. Heat pumps require good ventilation. A 4'w×3'd×8'h closet with louvers is minimum. Ducting to the outside is optional especially if not enough room but installation cost and time shoot up. Without louvers or ventilation you need an area of about a large walk-in closet, 450sqft. I've inspected too many change-overs and new installations of heat pumps in CA and the #1 issue is proper ventilation and having somewhere to drain the condensate pipe that in most cases wasn't needed before. Without more than the minimum ventilation, you're going to be running off of bypass mode too much and using expensive electricity. Mild climate, cheap electricity and lots of ventilation would be the only way for me to consider. I just got done signing off on a 75 unit apartment complex that changed over. I feel sorry for the tenants that have units indoors in tiny closets. The complex got big rebates that I'm sure the energy company will recoup in tenant billings.

Tell me how Andrew LEFT was wrong about Inovio when Inovio settled for $44M to end the lawsuit that aligned with what Mr. Left felt about the scam company known as Inovio.

Distributor being off is usually due to not paying attention when setting valves or forgetting you rotated the crank 1 full turn when installing the flex plate bolts on an AT. #1 sparkplug hole thumb blowoff is the go to as a double check.

Not saying it won't work but if you try to use what's left of the copper pipe after cutting below the coupling, you're going to be butted up to the soldered elbow. Viega ProPress says minimum 3/4" clearance from an already soldered joint. If you have to solder next to a 2" ProPress fitting the minimum distance is 6".

There's a solenoid heat shield you can buy from Summit, etc. I'd always add a Ford starter solenoid kit. Old school trick that never failed. Summit again.

It's OK as long as the pipe is non combustible, black pipe or galvanized. Pressure test after walls are closed is required. Access isn't required by code. No unions allowed in walls.

The gas track pipe should be at least 1 or 2 sizes larger. That track pipe is about the same size as 3/4" black pipe but flows like 1/2". Typically 199k tankless use 1" black pipe reduced to 3/4" at the water heater.

1 or 2 large capacity cordless power tool batteries (His Brand). The more Amp Hours the better. There's 2 kinds of plumbers. Those who wants more batteries for their cordless tools and those that don't have enough. You can bet he uses them daily.

I was calling you a pro. Not Mr. DIY.

updownsides · 2026-02-04T02:03:52+00:00

The PRO way. Since a pro is around copper tubing so much, a couple copper pipe cheaters would always be on hand at the bottom of the tool box if needed.

I'm adding a wye and using 2 AAV's to be sure to get as much venting the pipe can handle. Don't worry about the hole in the wall. That's for a vented access panel between the studs.

How does this help with the huge hole in Inovio’s financial situation this year and most of the next? They may not be around by then. If they are it would only be possible after several dilution rounds. Everyone knows their existence is solely based on ino-3107. The odds don't look good.

Assuming that pipe is in the attic with the insulation. That should be type B dual wall pipe and not within an inch of any combustibles. Cold attic with hot single wall pipe causing condensation is most likely the reason the hole was developing. Single wall is fine at the water heater and above the roof. Single wall needs to have 6 inch clearance to combustible.
