New Home Plumbing

I'm building a new home and am getting a bid for all plumbing work. What kind of questions do I need to ask when getting a bid?

Thanks, John

Start by having a copy of the plan for the plumber.
This way the plumber knows what he/she is up against.

If it is a new home, the plumber must be licensed.

Make sure to get a written estimate and/or a contract including, all materials, estimated times for installation and completion and breakdown with timing of payments.

Here is a list of things to consider asking:

Is he/she insured?
(If avoiding the question, ask for insurance certificate.)

How long has the plumber been plumbing new construction.
(You don't want someone that is primarily a service plumber.)

How busy is the plumber? You want someone that can complete the job within the time frame.

Is it septic or sewer, and where is the pipe entering the foundation?

Is it city water or a private well, and where is that pipe entering the foundation.
If a well, who is installing the pump,tank,etc

What type and size water heater do you want/need?
What will the location of the water heater be?
Is it electric, gas (LP or Natural), or oil?
If it is gas, who is doing the gas piping?
(The plumber or heating contractor?)
What type of venting is required for the water heater?
(It could make a difference on location of heater.)

Who supplies and insulates behind the tubs.
(this must be done before the tubs go in.)

Who is installing the roof flange?

(Some plumber will not go on the roof.)

Who is supplying the fixtures and faucets?
What kind of fixtures and faucets are being supplied? (brand,model,etc.)
Is there a fixture/faucet allowance?
You may not like the fixture/faucets he picked out and may want to upgrade.
(Be prepared, depending on what you pick out can also affect the labor pricing.)
How many sillcocks (outside faucets) are wanted and/or required, and where are they to be located?

What type of water supply piping is the plumber using? (WattsPEX, Uponor/Wirsbo, CPVC, or Copper?)
What type of drainage piping will be used?
(PVC, ABS, Cast iron)

The types of materials may not make a difference to you, but could make a difference in pricing.
(Copper is very expensive right now.)

Well, this should keep you busy for a while. I think I covered most items.
