Working in Garston
We work right across Garston — L18, L19, L24 and 1 more postcode districts — and in neighbouring Hunts Cross and Allerton.
Garston gets the same process as anywhere else: a free survey at your home and a written, itemised quote. In Garston flats, any change to the WC or wastes is planned with the lease and the flat below in mind. If your Garston home has a gravity system with a loft tank, we check the head of water before recommending a shower or a pump.
Supplies across most of Merseyside 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
- Basin, bath and shower wastes sized and laid to a steady fall, with traps that hold their water seal
- 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
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 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.
