Working in Southampton
We work right across Southampton — SO14, SO15, SO16 and 3 more postcode districts — and in neighbouring Hythe and Totton.
Southampton is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Southampton water is hard, a scale reducer or softener on the bathroom supplies can protect valves and shower heads. If your Southampton bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go.
Supplies across most of Hampshire are hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- New hot and cold pipework in copper or plastic, properly clipped, and insulated where it runs through cold spaces
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- 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.
Shower supply
Combi boilers and unvented cylinders give mains pressure. A gravity system with a cold tank may need a pump, but a pump must never be connected to the mains.
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.
