Working in Carrickfergus
In Carrickfergus we cover BT38; we also cover Newtownabbey, 5.6 miles away, and Bangor.
In Carrickfergus, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Carrickfergus bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. If your Carrickfergus home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Supplies across most of County Antrim are soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- The WC connected to the soil stack, or a new branch where the WC is moving
- A pressure test of new pipework before walls are closed in and floors go down
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- A check of your hot water system, and the pressure and flow rate at the bathroom
Decisions to make first
Pipe routes
Drilling through the middle of joists, rather than notching the tops, keeps the floor strong. Routes are planned with the joist direction in mind.
Gravity or pumped waste
Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.
Rules that apply in Northern Ireland
In Northern Ireland, the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 apply to new fittings. New drainage and connections are a matter for building control.
