- Drainage across London, with plumbing alongside
Hanwell sits on the slope down to the River Brent and the Grand Union Canal, and that slope affects how the drains behave.
Ground that drops towards a river gives drainage plenty of fall, which is generally a good thing: steep runs self-cleanse and rarely silt up. The trouble comes at the bottom. Where the fall flattens out near the Brent and the canal, everything the steep sections have carried down arrives at once and settles, so silting is more likely in the lower streets.
The housing is mostly late-Victorian and Edwardian terrace with the salt-glazed clay drainage of its period, plus interwar building on the higher ground. Mature trees in the parks and along the river corridor mean roots can be a problem where joints have opened. Properties backing onto the river or the canal have the additional issue of a high water table at the bottom of the garden, which lets groundwater into any joint that has opened. Jetting clears silt properly, where rodding only makes a channel through it.
Streets nearest the Brent and the canal can collect what the steeper runs above wash down. Jetting clears it properly; rodding only channels it.
Damp ground and mature trees along the river corridor. Roots find open joints in Victorian clay and come back until the joint is sealed.
Near the water the table sits high, so an open joint takes water in as well as letting it out, and the drain never runs clean.

Sinks, toilets, gullies and main drains cleared, with the cause identified rather than guessed.
Overflowing gullies and blocked manholes or inspection chambers, cleared and explained.
Toilets that will not flush, or that fill up and will not drain, cleared without damaging the pan or the soil pipe.
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 Hanwell, answered for the kind of property you find there.
Fall. Hanwell drops towards the Brent, so drains on the higher ground move debris along quickly, while lower runs, where the ground flattens, are where it tends to settle.
Possibly not. Near open water the table can sit above the drain, and where a joint has opened the pipe takes groundwater in continuously. It then runs part-full, loses the flow that keeps it clean and silts up. Clearing it again will not help; finding the defect will.
