Brevard Exam Reference

Prov Brevard; not a statewide field-code statement

First identify your city/county licence and accepted examination. As one current local example, Prov’s Brevard Journeyman Plumber page lists 80 questions, 180 minutes, $90 and 75%, with 2020 Florida Plumbing Code and Plumbing Basics for Contractors, 3rd edition. The exam’s listed book edition is distinct from the code governing a current construction project. FS 489.1455 separately sets conditions for statewide recognition of qualifying local journeymen.

Sample FL Plumber Practice Questions

1A building drain carries 40 DFU, including three private water closets, at 1/4 inch per foot. Under 2023 FBC–Plumbing Table 710.1(1), a 3-inch building drain carries 42 DFU at this slope; drains serving water closets must be at least 3 inches. Which conclusion follows?

A.A 2-inch drain is adequate because each water closet flushes only 1.6 gallons

B.A 3-inch drain is prohibited whenever a third water closet is added

C.A 3-inch drain satisfies these load and minimum-diameter checks

D.A 4-inch drain is required because 40 DFU exceeds the 3-inch horizontal-branch limit

Explanation: The building-drain table permits 42 DFU on a 3-inch drain at 1/4 inch per foot. The 40-DFU load is within that capacity and the 3-inch water-closet minimum is met. Table 710.1(1) does not impose the claimed two-water-closet limit. A horizontal branch is a different sizing application.

2The plan below places the building sewer west of the fixtures. North is up, and the arrow is labeled as drainage flow. Which drawing correction is needed? ```text NORTH ^ WEST EAST sewer <--- junction fixtures flow ---> ```

A.Reverse the north arrow while retaining the drainage arrow

B.Reverse the mislabeled east-pointing drainage arrow toward the west sewer

C.Retain the east-pointing arrow as the downstream viewing direction

D.Reverse the east/west labels while retaining the north arrow

Explanation: The sewer lies west, so the drainage arrow toward it must point west. Projection or a north label does not reverse the actual flow route. Correct the conflicting annotation before layout.

3A 48-foot horizontal run of 3-inch sanitary drainage pipe has 5 inches of available fall. No special engineered design applies. What is the smallest additional fall needed to meet Table 704.1 of the 2023 FBC–Plumbing?

A.0 inches

B.1 inch

C.7 inches

D.19 inches

Explanation: The minimum slope for 3- through 6-inch horizontal drainage piping is 1/8 inch per foot. Required fall is 48 × 1/8 = 6 inches, so the available 5 inches is short by 1 inch. This slope is approximately 1.04 percent, not exactly 1 percent.

4Using 2023 FBC–Plumbing Table 709.1, what drainage fixture unit value applies to one private-use, 1.6-gpf gravity-tank water closet when rated individually?

A.2 DFU

B.3 DFU

C.4 DFU

D.6 DFU

Explanation: Table 709.1 assigns 3 DFU to a private-use 1.6-gpf water closet. The question specifies a gravity tank: a flushometer-tank water closet has its own 4-DFU row, whether public or private.

5A Florida journeyman plans to operate a business contracting for plumbing projects in jurisdictions throughout the state. Which credential has statewide contracting authority under section 489.105, Florida Statutes, subject to the applicable licensing and business requirements?

A.A journeyman license issued by one Florida county

B.A DBPR certified plumbing contractor credential

C.A DBPR registered contractor credential for only one local jurisdiction

D.A local plumbing apprentice registration

Explanation: Section 489.105(8) distinguishes a certified contractor, who may contract throughout Florida, from a registered contractor whose authority is limited to the jurisdictions for which registration is issued. Local journeyman recognition is not conversion to a contractor credential.

6A candidate has a county authorization for a local journeyman plumbing test. A search also finds a DBPR certified plumbing contractor reference list. Before choosing books, which comparison is essential?

A.Use the contractor list whenever it contains a newer code edition

B.Use the edition on the newest practice-book cover regardless of test code

C.Match the county authorization, provider test code and current approved reference list

D.Combine all editions because open-book tests accept any published code

Explanation: Florida local journeyman testing and DBPR contractor testing are different credentials. Match the authorized jurisdiction and provider test code to that examination’s current reference list and rules. A code adopted for field construction is not automatically the edition approved for every local examination.

7Three proposed potable connections are reviewed. A is a continuously pressurized health-hazard chemical process capable of backpressure; B is a private well cross-connected to the public potable system; C is chemical-free irrigation with an AVB upstream of zone shutoff valves. Which complete correction set follows Chapter 6?

A.A: double check; B: retain with RP; C: retain AVB and downstream valves

B.A: RP; B: retain with RP; C: correct the AVB/valve conflict

C.A: RP; B: remove cross-connection; C: retain AVB and downstream valves

D.A: RP; B: remove cross-connection; C: correct the AVB/valve conflict

Explanation: A needs protection suitable for health hazard, continuous pressure and backpressure. B is a prohibited private/public potable cross-connection, not a connection legalized merely by an RP. C conflicts with the AVB downstream-valve restriction. Each line requires its own hazard and installation analysis.

8For an ordinary fixture trap without an approved special deeper-seal design, what is the minimum liquid seal depth under 2023 FBC–Plumbing section 1002.4?

A.1 inch

B.2 inches

C.3 inches

D.4 inches

Explanation: Section 1002.4 specifies a liquid trap seal from 2 through 4 inches for the ordinary case. A special deeper seal requires approval and the required access; it does not change the ordinary minimum.

9A building’s ordinary fixture distribution system measures 94 psi with all outlets closed. No exception applies. Under 2023 FBC–Plumbing section 604.8, to what maximum static pressure must an approved pressure regulator reduce the supply?

A.60 psi

B.80 psi

C.100 psi

D.125 psi

Explanation: Where static pressure exceeds 80 psi, section 604.8 requires an approved pressure-reducing valve with strainer to reduce pressure in the distribution piping to 80 psi or less. Static pressure is measured without flow; it is not the residual pressure during demand.

10The drawing legend defines solid lines as drainage and dashed lines as dry vent piping. A lavatory discharges through a solid segment that also provides an approved wet vent for a downstream fixture. Which notation makes that segment unambiguous?

A.Change it to dashed line and delete its drainage load

B.Keep it solid and label its wet-vent function, size and connected fixtures

C.Show the segment as dashed dry vent but retain its connected drainage load

D.Keep it solid but mark wet vent only on the upstream dry-vent riser

Explanation: A wet-vented segment conveys drainage while also providing a venting path under the applicable arrangement. Following the supplied legend, retain its drainage depiction and identify the dual function and connections. Line styles are drawing-specific, not a universal rule that all venting paths must be dashed.
