91 ft · 1" PEX
42 ft · 0.5" PEX
50 ft · 3" PVC Sch 40
Fall at 1/4 in/ft target: 12.6 in (1.05 ft) over 50 ft.
41 ft · 2" PVC Sch 40
No slope target set for this drain run — set a target and verify it with the local AHJ.
43 ft · 1" HDPE
Trench run — depth, bedding, cover, and utility separation to be verified in the field.
20 ft · 4" PVC Sch 40
Sleeve crossing — verify sleeve size for the carrier pipe and seal requirements at structures.
Cleanout placement (planning checklist)
☐ Cleanout accessible at or near where the building drain leaves the structure — verify with licensed pro / AHJ ☐ Cleanout access not blocked by equipment pads, landscaping, or paving ☐ Long horizontal drain runs have intermediate cleanout access — verify with licensed pro / AHJ ☐ Direction changes greater than 45° have cleanout access where practical — verify with licensed pro / AHJ Valve & access (planning checklist)
☐ Main shutoff valve located and accessible ☐ Isolation valves at equipment (heater, pump, tank) for service without full shutdown ☐ Valve boxes/access panels planned where valves are buried or concealed ☐ Water heater has required clearances, pan/drain, and relief-valve discharge path — verify with licensed pro / AHJ Trench & sleeve (planning checklist)
☐ Trench depth, bedding, and cover match pipe material and local frost line — verify with licensed pro / AHJ ☐ Marking/tracer tape or wire planned for buried non-metallic lines ☐ Compaction plan for trench backfill under paving or slabs ☐ Sleeves sized to pass the carrier pipe with couplings (typically 2 pipe sizes up) — verify with licensed pro / AHJ +2 more in the plan packet Crew checklist
☐ Call 811 / utility locate completed before any trenching ☐ Trench depth and bedding match pipe material and local frost line — verify with licensed pro / AHJ ☐ Sleeves placed where lines cross footings, slabs, or driveways ☐ Pressure test / leak test planned before backfill or close-in — verify with licensed pro / AHJ +2 more in the plan packet Planning aid only. Verify against local plumbing code, AHJ, permit authority, field conditions, and qualified professional review before real-world use.
What you're looking at
A service-to-fixtures rough-in over the real lot: meter → main → water heater → branches, drains with slope targets and computed fall, an HDPE service trench, and a driveway sleeve.
Notice the Floor drain tie-in warning — no slope target was set, so Munda Field Planner flags it before the crew finds out in the dirt. That's the point: catch missing decisions in planning, not in the trench.
