Debated on separating these as multiple posts, but here goes: - Can i get away with installing a flat kitchen sink island with a loop vent. I have seen construction details showing this but the top of the loop doesn't (and can't) reach above the top of the sink - What is considered an...

I am putting a new DWV system in at a 124 year old structural brick building i own in richmond, virginia. Have read through the IPC and believe the layout in this drawing will pass but want to run this drawing by folks on here to make sure im not missing anything before i glue it. I've drawn a...

Can anyone provide an example (or multiple) of how IPC Section 917 can be used in a residential setting for a two-story home with stacked bathrooms (shower, WC, lav)? I'm particularly interested in how that section allows toilets to use the same stack (if at all). I'm having trouble...

Can you all show me how IPC section 917 on single stack vents could be used for two bathrooms (tub, toilet, lav) that are stacked on top of one another (first floor, second floor). My appreciation is that the code generally doesn't allow toilets to be in a vertical stack, but that you can have...

Does anyone see a code violation with this design? My municipality uses 2012 IPC. It's for stacked bathrooms, with lav, toilet, tub/shower + a washing machine in two-story home. Slab on grade, so the lower fittings are in the earth. I'm proposing 1.5" fittings for everything except the...

I am in the process of adding a washer and dryer on the second floor of my two story home. They will be located on the other side of the wall from a bathroom group (tub/shower, toilet, and lavatory) so I have relatively good access for routing the drains and supply lines. My question is what is...

According to IPC is there a minimum depth to the drain pipe under a basement slab? My Dad told me 4" minimum below the slab but I can't find that in the 2018 code. Anyone know what section IPC requires depth to drain pipe under slab? Thanks! John

When did the code change to require bonding hot, cold & gas on a hot water heater? Which code cycle? I need to address an issue if a given water heater without bonding was legally installed such at the time -- in California. I know CEC 250.104(B) is part of it, and the date is at least 2011.

Hi, I am working on a restaurant in Georgia. The city is requiring me to include a bi-level drinking water fountain in a sit-down restaurant. Seems a little odd since sit-down restaurant serve water for free. Does anyone know why this may be required? Is it required by International Plumbing...

In our area inspectors are now tagging TPR valves that don't have a constant gravity drain slope, even in otherwise simple water heater replacements in basements. This is supported by IAMPO 608.5: 608.5 Discharge Piping. The discharge piping serving a temperature relief valve, pressure relief...

First time I'm using this forum... I am doing a remodel with approximately back to back kitchen and lavatory sinks. The 2" drain and vent pipe is offset with a 2"x2"x2" sanitary tee to attach the 2" horizontal drain line to. I am considering attaching a 2"x 1 1/2" x 1 1/2" sanitary tee with a 1...
