Hi,

I am installing an outdoor BBQ in an island with a sink and have a few questions. The BBQ island will sit on a concrete pad that is continuous from the island to the house. All utilities will be covered from the BBQ to the house and will enter the basement through a hole in the footing of the house.

1. What type of pipe should I use the for the hot and cold water?
Copper, galvanized cast iron, ?

2. I am using marine wrapped cast iron for the gas line but I am using black cast iron fittings. How do I provide protection to the fittings that is similar to the marine wrap on the pipe?

3. Do I need to have a ground wire associated with the gas line? If so, from where to where should it run?

4. I intend to run electrical in rigid conduit (PVC).

5. I intend to run a 2" ABS drain line to the sewer connection.

6. How deep do the services need to be if they are under a 3.5" concrete pad for:

Water lines?
Gas line?
Electrical PVC conduit?
ABS drain line?

Answers with details are greatly appreciated.

In My Professional Opinion

Hello: T. Nash

Answers to be provided by the numebrs in which they where asked.

#1
My recommendation would be to suggest using copper piping.

#2
Purchase a roll of pipe wrap designed specifically for this purpose from any plumbers piping supply dealer, wholesailer, plumber or retail hardware store.

#3
No grounding wire is needed, required, recommended or suggested on or to any gas lines.

Contact your local gas supplier for specific additional rules, regulations, reasons & information as it pertains to their utilities*.

#4
*Before installing any electrical and or gas utilities, I would highly suggest you contact the specific utilities for the reasons already suggested in #3 above.

#5
Connecting to any existing sewage line in almost any area of the country requires a city permit & approval. Same may apply to other utilities and most building construction.

#6
Depth of services is a code requirement, in many if not all, areas of the country. Once again, I would suggest & highly recommend you inquire on these matters with the building department in your area.

Cautions:
A:
Failure to make home modifications meet code may void any existing homeowners policy currently in place.

B:
There is always the risks of fires and or explosions present on jobs completed without proper installations.

C:
Violating local laws & codes could result in fines & penalties, which can be excessive.

C & D:
Failure to comply with city rules & codes most likely will result in the local department heads {"Gestapo Leaders"} to create an assortment of grief, discontentments and $$#@#&^%!! in your project & life... Best to avoid this aspect of the project.

And there you have it..."My Two Cents Worth"...

Regards & Good Luck

Thanks Tom_B.

I have pulled the permits already but, as always, I am trying to keep from having multiple visits from the inspector while I am trying to schedule the crew that is doing the concrete work.

I have found a burial guide for the city that I live that is helping but there are details that I am missing. Such as:

1. Do the copper pipes need to be wrapped in anything? I have seen some thin poly sleeving at home depot - from Oatey, both red and blue for hot and cold - but it didn't seem as though it would really provide any protection, and do you really need a different color sleeve for hot and cold?

2. Can the hot and cold run through the same 1.5" hole in the concrete footing or do you need a separate hole for each?

3. I have found that sewer and water supply can not be in the same trench. How far do trenches need to be separated?

Thanks for you input!

Copper water lines are suitable for direct burial but your local code would dictate what type of pipe to use. The only issue is the distance to your island and retaining heat in the HW line.
The hole that goes through the concrete should have a poly sleeve to prevent the copper from corrosion where it touches the concrete.
The power wire and the gas line should also not be in the same trench.
Again your local code will tell you the depth and spacing of the trenches.

Thanks GregH.

Is there any need to use the color coded poly sleeves (red for HW and blue for cold) or can I just buy one sleeve color and use it for both?

I don't think the copper really cares. In trade circles though it is the small details that make for a quality job.
