3. Dishwasher Hook-Up & Kitchen Plumbing Services
A proper dishwasher installation requires attention to detail. The plumbers available on Thoonjo Errands follow strict installation steps to ensure efficient performance and long-term safety.
1. Setup & Water Supply Connection
Your plumber connects both cold and hot water lines (if your dishwasher supports it), ensuring correct pipe sizing and tight, leak-free fittings.
2. Drainage Alignment
The drain hose must be aligned with the sink’s drain system to prevent backflow or dirty water returning to your dishwasher.
3. Electrical Coordination
Where needed, the plumbing professional works alongside a certified electrician to ensure safe electrical connection, correct earthing, and proper circuit load distribution.
4. Pressure & Flow Testing
Your technician performs:
Pressure tests
Flow rate evaluation
Drain tests
Leak inspection
This ensures your dishwasher runs efficiently without stressing your plumbing system.
5. Safety Inspection
Before completing the job, plumbers check:
Air gap or high loop compliance
Water hammer risk
Proper sealing
Temperature consistency
Drain route integrity
This guarantees long-term safety and prevents future problems.
4. Air Gap vs High Loop – Which Is Best for Nairobi Kitchens?
Backflow prevention is one of the most misunderstood parts of dishwasher installation. Many homeowners — and even some fundis — overlook this crucial requirement.
Air Gap (Recommended)
This is a small device installed near the sink that prevents used water from flowing back into the dishwasher.
High Loop
The drain hose is looped high under the countertop to create an air barrier.
✔ Which Should You Use in Nairobi?
Both options are acceptable depending on your sink and countertop design.
Professionals listed on Thoonjo typically recommend air gap systems because they offer better protection, hygiene, and long-term reliability.
5. Garbage Disposal & Sink Integration Services
You can find plumbers who offer:
- Garbage disposal installation + replacement
- Sink tailpiece modification for dishwasher connection

- Waste line optimization
- Noise-reduction fittings
These upgrades ensure water flows efficiently from your sink and dishwasher into the main sewer line.
6. Hot Water Supply & Water Hammer Prevention
Dishwashers require stable hot water (usually 50–60°C). Low temperature reduces cleaning performance, while sudden pressure spikes can damage pipes.
Plumbers on the Thoonjo platform can help with:
- Hot water line extensions
- Dedicated hot water supply setups
- Pipe insulation
- Water hammer arrestors

This ensures your dishwasher receives consistent hot water and avoids pipe banging.

12. Bathroom Plumbing FAQ
1. Do I need a plumber or a contractor for a bathroom renovation?
A plumber handles pipes, drains, fixtures, and waterproofing checks; a contractor manages structural work, tiling, and finishes. We can coordinate both.

Common causes include a broken drain, cracked grout, failed membrane, leaking mixer, or loose pipe connections.
3. Can you fix a leaking shower without removing tiles?
Sometimes yes if the problem is with sealant or surface fittings. But if the waterproofing has failed, tiles must be removed for proper repair.
4. Do I need permits to move a toilet or shower?
Yes, when drains, vents, or plumbing layout changes. We guide or handle the permit process.
5. How long does bathroom plumbing take?
Small repairs: a few hours.
Full renovations: 5-14 days depending on complexity.

Yes, we provide warranties on workmanship and selected fixtures.
