Working in Warminster
In Warminster we cover BA12; we also cover Westbury, 3.9 miles away, and Frome.
Being a smaller town does not change how we work in Warminster: free survey, written quote, one team. If your Warminster bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. In Warminster flats, any change to the WC or wastes is planned with the lease and the flat below in mind.
Supplies across most of Wiltshire 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
- Isolation valves on every fitting, so taps, cisterns and valves can be serviced without draining the system
- A pressure test of new pipework before walls are closed in and floors go down
- Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
- 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.
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.
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.
