Minnesota adopted a new accompaniment accouterments cipher on January 23, 2016. We’ve consistently had a civil accouterments code, but for the aboriginal time Minnesota has adopted a civic accouterments cipher — the 2012 UPC — forth with our accepted account of amendments.
The Minnesota amendments to the 2012 UPC can be begin here, but it’s all adequately abortive advice after the 2012 UPC. Thankfully, there’s a distinct book that combines the 2012 UPC forth with the Minnesota amendments, which can be purchased here: Minnesota Accompaniment Accouterments Cipher Book. This cipher is additionally accessible online for chargeless in pdf architecture here: 2015 Minnesota Accompaniment Accouterments Code.
I’ve paged through the new accouterments code, and there are a ton of changes. I couldn’t possibly analyze every change that has been made, but I’ve put calm a account of some noteworthy stuff. Best of these are changes, but some of them are simply diction changes that accomplish things clearer. This new cipher is absolutely easier to apprehend and understand, as far as I’m concerned. If I accept any of these changes wrong, amuse email me or leave a comment.
There are some sections that I haven’t yet ample out how to interpret, such as a new anniversary testing claim for abatement blockage assemblies (603.4.2). So I’ll apparently chase up with one or added blog posts after this year, highlighting some of these changes as I apprentice added about them. The argument in italics below are fractional quotes from the new accouterments code.
The old Minnesota accouterments cipher referred to alfresco faucets as “sillcocks.” I frequently acclimated this accent in blog posts and home analysis letters in an attack to be consistent. I can’t acquisition the chat “sillcock” anywhere in the new accouterments code, so I’ll be calling them corrupt bibbs from now on.
The rules for hangers and supports accept afflicted a ton. Besides the agreement changes, artificial pipes that back decay from dishwashers or agnate hot baptize wastes no best charge to be accurate on affiliated metal or copse strips. See Table 313.1
The minimum admeasurement for battery drains acclimated to be 1-½”.
Showers shall accept a decay aperture and accoutrement tailpiece not below than 2 inches (50 mm) in diameter.
The old accouterments cipher didn’t specify the minimum amplitude for a battery door.
Shower doors shall accessible so as to advance not below than a 22 inch (559 mm) bare aperture for egress.
My assumption is that this claim is alone for battery receptors congenital on-site, but it’s not clear. The cipher says that showers charge to be flood activated by bushing the battery with baptize to the akin of the asperous threshold. It’s not bright how continued this analysis needs to booty abode for, but I’ve been told it’s a minimum of 24 hours.
Shower receptors shall be activated for watertightness by bushing with baptize to the akin of the asperous threshold. The analysis bung shall be so abode that both high and below abandon of the subpan shall be subjected to the analysis at the point breadth it is clamped to the drain.
OK, maybe I’m paraphrasing, but that’s what it comes bottomward to. From now on, the battery needs to be advised so one needn’t booty a battery to analysis the shower.
Control valves and showerheads shall be amid on the sidewall of battery compartments or contrarily abiding so that the showerhead does not acquittal anon at the access to the alcove so that the bather can acclimatize the valves above-mentioned to dispatch assimilate the battery spray.
You apprehend that appropriate (and yes, I paraphrased again). Air gaps are now appropriate on dishwasher drains. I don’t apperceive how accouterments inspectors will be administration this new requirement, but the plumbers I’ve talked to say that an air gap will be appropriate any time a dishwasher is installed or replaced. Sorry, but yuck.
The diagrams aloft were supplied by the accomplished association at Cipher Check, who gave me permission to mark them up.
No calm dishwashing apparatus shall be anon affiliated to a arising arrangement or aliment decay disposer after the use of an accustomed dishwasher air gap applicative on the acquittal ancillary of the dishwashing machine. Listed air gaps shall be installed with the flood-level (FL) appearance at or aloft the flood akin of the bore or drainboard, whichever is higher.
When a baptize boiler is installed aloft an breadth area a aperture would account above damage, an emergency cesspool pan is now required. Area 507.5 of the cipher additionally prohibits the abatement valve from absolution into this cesspool pan. This won’t affect best Minnesota homeowners, because best baptize heaters are installed on a accurate attic in the basement.
Where a baptize boiler is amid in an attic, attic-ceiling assembly, floor-ceiling assembly, or floor-subfloor accumulation breadth accident after-effects from a aperture baptize heaters, a absolute pan of corrosion-resistant abstracts shall be installed below the baptize boiler with not below than ¾ of an inch (20 mm) bore cesspool to an accustomed location.
A actual austere estimation of the minimum adequate aqueduct bore banned the use of angle connectors at water heaters in the old code. Not so any more.
Flexible brownish baptize boiler connectors or able adjustable baptize boiler connectors abutting baptize heating to the brim arrangement shall be in accordance with the applicative standards referenced in Table 1401.1. Chestnut or stainless animate adjustable connectors shall not beat 24 inches (610 mm).
When antithetical metals are affiliated to anniversary added and baptize passes amid them, a active acknowledgment can occur, causing the below blue-blooded metal to corrode. I apperceive this is a big accord in some genitalia of the country, but not actuality in Minnesota. I usually see access amid galvanized animate and chestnut captivation up aloof accomplished over continued periods of time, but they’re no best allowed. To affix chestnut tubing to threaded aqueduct joints, there charge now be a assumption adapter, a 6-inch assumption nipple, a dielectric fitting, or a dielectric abutment used. There’s absolutely a bit of argument to this cipher section, so I won’t adduce it here.
There has been abundant altercation over what constitutes adequate abstracts for abatement valve acquittal tubes, but the new accouterments cipher makes it absolutely clear. Brim and accessories that accomplish up the acquittal tube may be fabricated from galvanized steel, adamant chestnut tubing, CPVC, or polypropylene. Or the acquittal tube may be a listed abatement valve cesspool tube.
Relief valves amid central a architecture shall be provided with: (1) a cesspool that is not abate than the abatement valve aperture and brim and accessories fabricated of galvanized steel, hard-drawn copper, CPVC, or PP; or (2) a listed abatement valve cesspool tube with fittings.
Unions makes it far easier to alter a baptize heater, and now they’re required. It acclimated to be adequate to artlessly adhesive chestnut tubing into abode on a baptize heater, which meant that replacing a baptize boiler consistently appropriate acid and soldering new chestnut tubing for the baptize lines, but a abutment makes for a quick and accessible break point that alone requires a brace of wrenches.
Unions shall be installed in the baptize accumulation brim not added than 12 inches (305 mm) of acclimation equipment, baptize heating, conditioning tanks, and agnate accessories that requires account by abatement or backup in a address that will facilitate its accessible removal.
The old Minnesota accouterments cipher required ¾-inch brim here. See Table 610.3
This is trivial, as the old cipher artlessly appropriate album of a allegory color. But still. Go Purple.
Where surfaces to be abutting are bankrupt and chargeless of dirt, moisture, oil, and added adopted material, administer album amethyst in blush in accordance with ASTM F 656.
The old cipher accustomed a best of 4 feet. See agenda 2 in Table 1002.2
That’s all for now. One change that anybody had apparently been acquisitive for was the allowance of air admission valves. These are accustomed by the IRC, but not by the UPC, which is what was adopted. Air admission valves are still not accustomed in Minnesota. Please acquaintance your bounded architecture official with any questions about interpretations, as my assessment doesn’t beggarly squat.
