Working in Porthcawl
We work right across Porthcawl — CF36 — and in neighbouring Bridgend and Maesteg.
Porthcawl gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Porthcawl home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump. If your Porthcawl bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Supplies across most of Mid Glamorgan 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
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- A pressure test of new pipework before walls are closed in and floors go down
- The WC connected to the soil stack, or a new branch where the WC is moving
Decisions to make first
Concealed or exposed valves
Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.
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 Wales
Wales also uses the Water Supply (Water Fittings) Regulations 1999 and has its own Part H for drainage. The same rule on macerators applies: there must be a gravity-drained WC elsewhere in the home.
