Working in Harrow
We work right across Harrow — HA1, HA2, HA3 and 2 more postcode districts — and in neighbouring Brent and Wembley.
In Harrow, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. In Harrow flats, any change to the WC or wastes is planned with the lease and the flat below in mind. For Harrow homes on a combi boiler, we measure the flow rate at the bathroom before you choose a shower valve.
Supplies across most of Greater London are very 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
- Draining down and isolating supplies, with the rest of the house back on water as soon as possible
- A check of your hot water system, and the pressure and flow rate at the bathroom
- 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.
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.
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.
