general information:
  • Plumbing Review is required before construction starts.
  • Fixture locations and technical specifications are needed to properly represent all of the information on the construction drawings.
  • Green specifications have additional requirements.
Please review information and tips below. The diversity of selections is tremendous and takes some Buyers much more time than expected. We suggest limiting your selections to a few suppliers. Comparisons can be very time consuming and may not result in large cost savings. We have literature available at the office or you can contact one of our authorized vendors.

Every Selection and Decision involves common procedures. Many items listed are based on our "Standard" features package. Please check your specifications for features unique to your home.
  • Review your Specifications for Product Information and Allowances.
  • Review the NAHB Performance Guidelines.
  • Review the Use and Care Guidelines.
  • A Worksheet may be provided for your use.
After making your selection, sign the Order Authorization or corresponding Allowance Invoice and forward it to us for execution. No orders will be placed without authorization and payment. If orders are not placed by their deadlines, construction may be delayed.

hints and tips:
Green and Energy Efficiency
Please ask about Green and Energy Efficient options available with these products and systems.

Hot Water
The location of the water heater, size of water piping and the routing of the piping affect how long it takes for hot water to get to a fixture. Depending on the floor plan, it may or may not be convenient to locate the water heater close to where you want hot water. Larger water piping will make it take longer for hot water to reach the fixtures. And, piping may be routed so that the most used fixtures are first in line, (i.e.: putting the powder bath ahead of the kitchen sink would not make much sense unless it saved a lot of piping). Please advise as to any special needs or concerns or the decisions about piping will be left to the Plumber's discretion.

Verify:  Roman tub spout - make sure the spout will clear the edge of the tub and is 2 inches above the water line.

Bath Accessories - Towel Bars / Toilet Paper Holders / Shower Enclosures+
Some Plumbing Fixture Manufacturers offer matching bath accessories, but you may find the cost for these to be much higher than generic brands.
Bath Accessories can be exceptionally expensive when matching a special color to your plumbing fixtures.
