The traps in the plumbing are what keeps sewer gasses out of the house, not the vents. The vents allow air on either side of those traps to equalize. Otherwise when you flushed a toilet, for example, the air on the sewer side of the trap would have no place to go and seriously impede the flow.
P3101.2 Trap Seal Protection
The plumbing system shall be provided with a system of vent piping that will allow the admission or emission of air that the liquid seal of any fixture trap shall not be subjected to a pressure differential of more than 1 inch of water column.
PS:
P3103.1.3 Roof Extension Covered
Where an open vent pipe terminates above a sloped roof and is covered by either a roof-mounted panel (such as a solar collector or photovoltaic panel mounted over the vent opening) or a roof element (such as an architectural feature or a decorative shroud), the vent pipe shall terminate not less than 2 inches (51 mm) above the roof surface. Such roof elements shall be designed to prevent the adverse effects of snow accumulation and wind on the function of the vent. The placement of a panel over a vent pipe and the design of a roof element covering the vent pipe shall provide for an open area for the vent pipe to the outdoors that is not less than the area of the pipe, as calculated from the inside diameter of the pipe. Such vent terminals shall be protected by a method that prevents birds and rodents from entering or blocking the vent pipe opening.
So since the vent pipe is just sucking in air, just cut it short and make sure the panel isn't acting like a "lid"? is there some kind of low profile box or pipe attachment solution? Im thinking like on of my vacuum attachments that has a wider open mouth.
@@will1498 Essential correct, though the vent both draws in and pushes out air as needed. Think when you flush, the water in the trap is pushed into the plumbing and the vent expels air to prevent the pressure from blocking it. Likewise, if barometric pressure were to drop the air pressure in the plumbing won't push water back through the trap into the home. Or, vice versa where increased barometric pressure, without a vent, would push water into the plumbing from the house side, possibly emptying the trap. Don't know of any low profile box solution, but that doesn't mean there isn't. I suspect the 2" requirement is to prevent water flowing off the roof from entering the pipe or from any snow or ice sliding down the roof under the panels from blocking the vent.
Glad you see you posting again! Very informative.
Thanks for making these videos! I enjoy the content & the quality/production is good. I work for an electrical utility in the meter department, so I deal with solar installs (a lot of hacks). I love how passionate you are, keep up the good work my man.
Thanks for your channel and sharing your perspectives. I am a Solar newb, but a DIY guy all the way, and also learned by taking everything apart I could, as a kid. I have 31x 715W bifacials that I need to install on my 40' HQ, still narrowing down ideas for mounting. I do like the idea of having a tilt option for Winter gains. It's great to see you show what has failed and what works. Subscribed now after a few vids.
Liked! Definitely not easy filming while working. Hats off for keeping the camera rolling while climbing a ladder and carrying a camera at the same time. Please be careful. Been installing since 2013. I think the rooftop PV will die soon in California. NEC3.0 made the ROI payback period too long and with new taxes on solar panels and batteries, honest solar companies will find it hard to capture new customers.
Man, having to remove panels only 10 years in for a roof replacement must really dig into the ROI
Well, if insurance covers the roof and the equipment survives the process, it shouldn't affect the ROI. Really annoying, though.
@@brianhaygood183 You'll pay for it with the insurance premiums. I didn't even think about the potential equipment damage.
Its super intresting what is happening to the Roof over Time with Solar Installation ( particularry those "not" perfect Installation ) . Particular the "Water" for the Roof.
In Germany we see more Problems with SolarModules and the Insulation , seems that Produktion around 2010 had faulty backplan Foil which gets cracked by UV over Time and then you have short circuits and 500V somewhere.
Originally I commented regarding your 1/24 video, but based on this video, feel it is more appropriate to put here. I appreciate your commitment to pass along ALL of your insights. Many people today, don't seem to understand how important this is. While you have pointed out so many of the mistakes that you have fixed, I thought I would see if you could create a video for what the optimal roof structure would be for a solar array for a long-term perspective both existing and new build scenarios?
Also, perhaps updating your best value, efficiency, and quality products video and including hail resistance (if there really is such a thing). I would like to see about the structure first, as I am inclined to think that many times the difference in money might be worth spending upfront for some additional carpentry. I'm not suggesting adding new rafters, but let us know your thoughts?
Perhaps it is a raised secondary structure? To your point the pipe vents could be moved by a plumber before a new roof is installed (but ideally where - within the 3' of the outside of the roof?). Also you bring up a great point about ventilation, I see many turtle vents, which are semi randomly placed. Is there a best placement for these (perhaps 1'-2' from the top of the roof?) Perhaps you could also include your experiences/thoughts about using newer roofing materials for underlayment, rubber roof shingles, metal roofs, best for areas that are very likely to get hail, etc.
I am more of a boots on the ground type of person as well, I appreciate hearing things from your perspective. It is so much more practical than those that are merely philosophers.
Were those bees or hornets/wasps? And brake cleaner makes great spray. We get 5gal containers of it to fill SureShot aerosol cans to save cost. WD40 + light oil in another SS works well too.
those were not bees, they were yellow jackets (wasps) which have a paper nest.
Ground mount only way to go. Some insurance considers it a secondary structure like a shed.
Enjoying this channel. I have to replace one of my panels with a new one that's wider and taller. I've reshuffled the panels to leave the empty spot at the upper left side of the array but the rails are about six inches too short to fit the wider panel. It is K2 rail. Any suggestions for extending the rail? The rails are 14' so don't think I can just buy a couple longer ones and trim.
Perhaps spray foam insulation is installed to under roof deck? If so there will be no soffit and/or ridge ventilation.,
What are you using to clamp your ladder to the roof. Seems real solid 👍
A solar system basically destroys a roof
Honest information about roof top solar don't see much of this on the internet. It's either how to install, solar sales pitches no one shows the problems that solar installers leave behind on a roof. That was a paper wasp nest they don't attack like a bee hive would.
With solar panel cost deduction from 10-15 yrs and the increased output versus cost, does it make sense to re-install newer panels getting more output using same roof area??
7:30 I agree with your method over the manufacturer. You're better off your way.
Properly installed, what flashing would you recommend?
Super video. Beginning to dabble with DIY now that panel prices are reasonable. What IV curve tracer do you use to test panels? What's a good place to get parts for roof mounting?
Check with your AHJ first. NEC has language added after 2014 that requires a "licensed contractor" to install rooftop PV. Some AHJs follow this to the letter (so no DIY), some don't and only mandate the owner-builder meets all code (NEC, structural and fire) requirements.
12 Watts output is scrap. Maybe cut the crimp connectors off and see if its just a bad connection.
The roof could be sealed. Insulated right under the roof sheathing and keep it as conditioned space.
😧...please keep WD40 off the (yet to be installed) new roof. Its like acid, breaks down shingles and anything else asphaltic.
Did you punch through the soffit and then the roof to run your AC?
I wish that you would stay at LA ca
What are the shades?
can you or client cut the long pipe & fit 2 elbows, swing the upright to a gap between panels. Get away with it down under kos our Bldg std's are crap 😜
bypass diodes may be toast
You should have said to have the pipes moved to the other side when rerooffed... Too late now...
There are different size rubber seals for different size wires for the connectors most people don't even know exist... partial fault of the connector company...
Don’t chop vents the hight of the vent is dictated by code. You can have them moved however.
I thought vent heights above the roof are only regulated for flues and chimeys, not plumbing vents or exahust fan vents.
@@brianhaygood183 I thought that to until my solar guy chopped mine down and I got my final inspection and the dude pulled out the Code. I had to move my vent. Size up as well because I was putting in an offset
@@brianhaygood183 best left to those animals known as plumbers - there is a fairly precise calculation to ensure you don't have fart gas locked up in your house.
I did a little research. The answer: 2"
IRC P3103.1.1 requires 6" above roof or anticipated snow unless P3103.1.3 applies, which specifically allows 2" height above roof when covered by such as a solar panel.
State codes may have their own version, particularly up North where they often require a larger minimum due to snow.
@@brianhaygood183 I get well above two inches of snow on my roof. Probably makes a difference and roof slope. Who knows I just know I wouldn’t cut any pipe that’s not your trade.
A roof doesn't need ridge venting if it has proper gable venting
If it "ain't broke", why are you fixing it?
Are you a c-10?
Can you talk numbers $ while doing these types of videos?
Did you just put panels on different roofs on same string without optimizers? That is a horrible idea.
Save your money and buy some land instead...
