Electrical & Plumbing Maintenance — Why Drawings Matter

I. Electrical Maintenance

Electrical maintenance ensures the safe, reliable, and efficient operation of electrical systems in residential, commercial, and institutional buildings. At EPC, electrical maintenance focuses on preventing failures, reducing safety risks, and extending the lifespan of electrical infrastructure.

Our electrical maintenance services include:

  • Inspection of wiring, switchboards, DBs, and MCBs
  • Load checking and identification of overheating points
  • Tightening of loose connections and terminals
  • Replacement of damaged or sub-standard components
  • Earthing and grounding checks
  • Preventive maintenance to avoid sudden power failures
  • Emergency electrical repair and fault rectification

With regular electrical maintenance, buildings experience fewer breakdowns, improved safety, lower long-term repair costs, and better energy efficiency.

II. Plumbing Maintenance (Detailed)

Plumbing maintenance is essential for ensuring uninterrupted water supply, proper drainage, hygiene, and structural safety of a building. In Nepal, plumbing issues are commonly caused by poor installation practices, low-quality materials, pressure fluctuations, and lack of preventive maintenance. EPC provides structured plumbing maintenance services designed to prevent recurring problems and reduce long-term repair costs.

Scope of Plumbing Maintenance Services

  1. Water Supply System Maintenance
    • Inspection of main supply lines, internal piping, and distribution points
    • Detection and repair of visible and concealed leakages
    • Pressure testing to identify weak joints and pipe stress
    • Maintenance of overhead tanks, underground tanks, and pump connections
    • Replacement of worn-out valves, taps, and fittings
  2. Drainage and Wastewater System Maintenance
    • Inspection of drainage lines, floor traps, and manholes
    • Identification and removal of blockages and slow-drain issues
    • Correction of improper slopes causing water stagnation
    • Repair of cracked or leaking drainage pipes
    • Odour control and prevention of backflow issues
  3. Bathroom and Kitchen Plumbing
    • Maintenance of wash basins, sinks, toilets, showers, and geyser connections
    • Repair of concealed pipe leakages in bathrooms and kitchens
    • Replacement of damaged flush systems, angle valves, and mixers
    • Waterproofing-related plumbing checks to prevent seepage
  4. Pump and Water Storage System
    • Inspection and servicing of water pumps and motor connections
    • Float valve and overflow control system maintenance
    • Tank cleaning coordination and leakage inspection
    • Ensuring proper suction and delivery line performance

Common Plumbing Problems Observed in Nepal

  • Repeated leakage due to poor jointing and low-quality materials
  • Improper pipe slope causing frequent blockages
  • High or fluctuating water pressure damaging pipes and fittings
  • Lack of access points for future maintenance
  • Temporary repairs instead of permanent solutions

EPC’s Plumbing Maintenance Approach

  • Use of certified and suitable piping materials (GI, PPR, CPVC, PVC, as required)
  • Trained technicians following standard installation and repair practices
  • Proper documentation of plumbing layouts and repair history
  • Preventive maintenance planning instead of reactive repairs
  • Clear billing and transparent service reporting

Benefits of Regular Plumbing Maintenance include reduced water wastage, prevention of structural damage, improved hygiene, longer life of plumbing systems, and fewer emergency breakdowns.

EPC delivers reliable plumbing maintenance through preventive planning, skilled technicians, and transparent service management—ensuring long-term performance of your plumbing systems.

III. Importance of Drawings in New Houses and New Structures

Proper drawings are the foundation of a safe, efficient, and maintainable building. In many new houses and structures in Nepal, electrical and plumbing works are carried out without accurate drawings, leading to repeated failures, safety risks, and high maintenance costs. EPC strongly recommends preparing detailed drawings before and during construction.

What Are Building Drawings?

  • Electrical layout drawings
  • Plumbing and drainage drawings
  • Water supply and pump layout
  • Earthing and grounding diagrams
  • Load schedules and panel layouts

Why Drawings Are Critical in New Construction

  • Safety and Compliance: Prevents overloading, short circuits, and fire risks; ensures correct earthing and protective devices.
  • Accurate Installation: Correct placement of switches, sockets, lights, pipes, and valves; proper pipe slopes for drainage.
  • Cost Control and Material Planning: Avoids unnecessary material wastage and repeated rework.
  • Easy Maintenance: Helps technicians locate concealed wires and pipes quickly, reducing repair time and risk of accidental damage.
  • Scalability: Makes future upgrades (AC, EV charger, solar, inverter) and expansions easier.

Although drawings require an initial investment, they significantly reduce repair costs, improve safety, and extend the life of the building. EPC recommends every new house and structure to have complete electrical and plumbing drawings before construction and updated as-built drawings after completion.
