Working in Penzance
As well as Penzance itself (TR18), we survey in Camborne, Redruth and Falmouth.
Penzance gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In Penzance flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Penzance water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads.
Water across much of Cornwall is 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
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- The WC connected to the soil stack, or a new branch where the WC is moving
Decisions to make first
Copper or plastic
Copper is rigid and suits pipes on show or near the boiler. Plastic is quicker under floors and inside walls, and long runs need fewer joints.
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 England
In England, the Water Supply (Water Fittings) Regulations 1999 apply. New drainage or a new connection to the soil stack can be building regulations work under Part H, and a macerator or pumped WC is acceptable only where there is also a WC on gravity drainage elsewhere in the home.
