    2019 Final Action Hearings Voting Question

    Not exactly. The Public Comment Hearing (PCH) has two functions, 1) Approve of the Committee Actions on the group of proposals that did not receive a Public Comment. Sometimes called the "block vote". ICC calls it the vote of the Consent Agenda. 2) For all proposals that had one or more Public...

    The problem with code development???

    In the Fall of 2020, folks can begin working in cdpACESS to generate I-Code proposals. The deadline to be completed with proposals is the first week of January 2021. These proposals will develop the 2024 I-Codes.

    IPC 417.4.1 Shower & Tub Walls

    Here is the Commentary for that section in the 2018 edition: The enclosure walls for tub/showers or showers must extend to a height of not less than 6 feet (1829 mm) above the floor level of the room or 70 inches (1778 mm) above the drain, whichever is greater (see Commentary Figure 421.4). The...

    Disposable Sink Traps?

    It always pays to be professional in one's communications...I have paid the price for the instances where I wasn't (i.e., I am human and have made mistakes)

    Service Sink

    I have recently seen some of the "big box" store restrooms with a hot water hose bibb on the restroom wall. There is a floor drain in the room. The IPC requires neither. I doubt that there are many code officials that would accept that as the required service sink but then, strangers things...

    Service Sink

    Here's the IPC Commentary concerning "service sinks": The “service sinks” required by Table 403.1 are intended to be of a type suitable for janitorial and building maintenance purposes. Service sinks include mop sinks/basins, utility tub/sinks, janitor sinks, slop sinks and laundry trays. Only...

    Disposable Sink Traps?

    IPC (and IRC plumbing) requirement 412.1.2 Waste fittings. Waste fittings shall conform to ASME A112.18.2/CSA B125.2, ASTM F409 or to one of the standards listed in Tables 702.1and 702.4 for aboveground drainage and vent pipe and fittings. If it complies with one of the standards, not much you...

    Water Heater P+T Valve

    The 2018 IPC (and 2018 IRC) began to directly addresses this internal reduction issue: 14. Be one nominal size larger than the size of the relief valve outlet, where the relief valve discharge piping is installed with insert fittings. The outlet end of such tubing shall be fastened in place.

    Water Heater P+T Valve

    And, 12. Not have valves or tee fittings.

    What happens if a city approves a deck that seems to violate fire codes

    Have we "run off the rails" with this one a little bit? We need to boil this down to two questions: Is there a zoning ordinance violation? In some areas (not necessarily yours), building a structure on the lot line could be acceptable. Sometimes there is a height restriction as you get closer...

    Failed Foundation Inspection

    IF the building is properly anchored to the slab (and that if a big IF),, is that enough to resist wind load to keep the building from blowing into your yard? Chances are that the metal building isn't heavy enough to cause a compression failure of the slab edges. But what about the anchoring...

    Is it allowed to bury Sch 40 gas pipe if wrapped with 20mil?

    I'm curious as to where these sections are coming from. National Fuel Gas Code? California? Edition year?

    3 Bay Sink plus One DWV

    Likely not. These waste pump units are typically used for an LT, LAV or Handsink. Only ONE of those fixtures, not a group of fixtures. Solids handling capacity is usually only 1/2 inch. They can be used for an ACW if the ACW discharges to an LT, serving as a surge basin. The only point I...

    Is it allowed to bury Sch 40 gas pipe if wrapped with 20mil?

    The IFGC (and the Fuel Gas part of the IRC) has had the similar language since the 2000 edition. I seem to remember from long ago that the Fuel Gas portion of the (1994??) SBCCI plumbing code (?) did speak of the 2 wraps of 20 mil tape on buried iron piping. The codes change every 3 years so it...

    3 Bay Sink plus One DWV

    That is not a grease interceptor on the left...it is a waste pump. The vertical pipe coming out of the top of it is the vent for the sump. Probably just an open pipe...or it might have an AAV on it. (However, an AAV only lets air into the sump as the sump pumps the level down. What happens when...

    Great work is often accomplished silently, without fanfare. Kudos to those who try to keep the forum "pure".

    DWV in Return Air Ducts

    You have missed my point. Here's a simple example: The IPC requires a 3 inch drain when the fixture drain from an ACW combines with another drain. The IRC does not have that requirement. Should you apply the IPC requirement to the IRC building? No, because the IRC has everything you need to...

    Question for the masses? Does a compression post have to be plumb?

    It looks like this 1:6 condition has been thought through: "Compression struts shall meet the following requirements: • The strut shall be sized to adequately resist the vertical component force induced by the ceiling bracing wires and have a maximum kl/r not to exceed 300. The struts listed...

    DWV in Return Air Ducts

    "I assume this is a SFR and since the IRC is silent on this, I will use the IPC and IMC." The IRC is intended to be an all encompassing bible for SFRs. Everything that one needs to build SFRs is in that book. The IRC covers ductwork/return air chases ("plenum") and DWV piping. The IRC does have...

    Now the next learning question is what do you do when the DW is in island that doesn't have a sink? (and the OPs photo may be just that situation.

    How NOT to drain a dishwasher

    It's always nice to know why the DW drain connection is not correct: 2015 IRC P2717.2 Sink and dishwasher. The combined discharge from a dishwasher and a one- or two-compartment sink, with or without a food-waste disposer, shall be served by a trap of not less than 1-1/2 inches (38 mm) in...

    Question for the masses? Does a compression post have to be plumb?

    A compression (or tension) member has to be aligned with the direction of the load. How close that alignment needs to be, depends on the type of end connections of the member and the stiffness of the member. If the end connections are pin only (full rotation allowed), the load direction and...
