Plumbing is fitting pipes together to move liquid.
Water mains (from well or boiler) typically use ¾” pipe. Pipes to fixtures (link sinks, showers etc.) are ½” pipe.
Two important factors are:
- Flow rate: Amount of water in litres per minute
- Static pressure: Pressure as measured in the pipe coming in
Fittings
Fittings usually come in brass and copper. They can be compression fit, push fit (tectite) or soldered.
| Number of fitting | Fitting type |
|---|---|
| 310 | Straight coupling |
| 315 | Elbow (right angle) bend |
| 318 | T Junction coupling |
Balancing Radiators
- Turn off boilers nearest the radiator
- Put the boiler on and wait for the furthest radiators away to get the hottest they can
- Slowly turn on radiators until you get back to the boiler

Filling Radiators with inhibitor
- Identify “highest” radiator
- Shut off fill (where TRV is) and return/lock valve on bottom of radiator
- Open the bleed valve and opposite valve at the top and keep both open
- Fill inhibitor from one side at top and look for water/air displacement from other side at the top
- Once inhibitor filled, close both top valves and open both bottom ones
- Run heating system for 30/40 minutes and check for air in radiators
