New Malden combines a busy High Street with plenty of restaurants and food businesses, and streets of 1930s semis on clay. The two produce very different drainage work.
The High Street has many restaurants and food businesses, often cooking at volume in premises whose drainage was installed long before that use. High-output kitchens discharging into shared runs under a busy street need the same answer anywhere: grease traps sized for the actual covers, serviced on a schedule rather than when someone remembers, and planned jetting timed to the trade rather than to a failure. Residentially, New Malden and Worcester Park are mostly interwar semi-detached housing on clay pipework, with long garden runs out to a boundary chamber. The ground moves with the seasons, opening joints and cracking sections, and mature garden trees find those openings. It is typical suburban drainage, but the runs can be long enough that rods cannot reach a fault, and a camera survey saves a lot of guesswork.
Food businesses discharging into shared runs. Undersized or unserviced grease traps can close lines that several premises depend on.
Seasonal shrink-swell opens joints in interwar pipework. Dry summers produce autumn blockages.
The distance between house and boundary chamber can put faults beyond the reach of rods.

Kitchen sinks and waste pipes blocked with grease, cleared properly rather than just poked through.
Standing water in the bath or shower tray, and slow bathroom basins, cleared at the cause.
Sewage backing up, drains overflowing, or a home or business you cannot use until it is fixed. Phone answered 24/7.
Scours grease, silt, scale and roots off the pipe wall, rather than just making a hole through the blockage.
See the inside of the pipe: recurring blockages, pre-purchase checks, insurance and subsidence claims.
Cracked joints, root damage and collapsed sections, repaired without digging where the pipe allows.
Restaurants, pubs, offices, landlords and managing agents: planned maintenance and out-of-hours call-outs.
Leaks, taps, traps, toilet cisterns and waste pipes: the plumbing that often comes with a drainage job.
Common questions about drainage in New Malden, answered for the kind of property you find there.
With busy kitchens, the first question is usually the grease trap: whether it was sized for your actual covers, and whether it is emptied on a schedule. Once a trap fills it stops separating and passes fat straight through, so it stops doing anything at all. Planned jetting on top of that is far cheaper than closing.
You may well be on the same run. Neighbouring premises on a high street often share drainage, so one kitchen managing grease badly closes a line everyone uses. Clearing it helps all of you; identifying the source is what stops it happening again next quarter.
