Jetting drives water through a drain at pressure, cutting through what is blocking it and scouring the pipe wall clean on the way back out. Monster Drainage jets drains throughout Banstead village, Nork, Tattenham Way and the wider SM7 area. Banstead sits on the chalk of the North Downs, and a good many properties here still drain through clay pipework laid decades ago, which is precisely the sort of run that repays a proper clean.
Chalk and the fine flint silt that comes with it wash into gullies every time it rains heavily on the Downs. In a drain with a shallow fall that silt settles rather than carrying through, and it builds a layer along the invert until the pipe is running at half its bore.
Rodding will punch a channel through silt and the drain will appear to clear. Within weeks it is back, because the deposit was never taken out of the pipe. Jetting lifts it and flushes it away.
The roads around Nork and the Downs edge are well treed, and mature roots will travel a surprising distance towards a leaking joint. Clay drains with mortar joints give them the way in.
A cutting head on the jetter takes root growth back to the pipe wall. Where it returns within a year, the joint itself has gone and the honest answer is a repair rather than another clean.
Fat leaves the pan liquid and sets in the pipe solid, and every wash after that adds to it. In a long kitchen run the narrowing is gradual enough that nobody notices until the sink is barely draining.
This is the single most common thing we jet out of domestic drains in SM7, and it is the one most easily prevented.
Glazed clay, modern PVC and older pitch-fibre each tolerate different pressures, and pitch-fibre in particular can deform if it is jetted like clay. Identifying what is actually in the ground before the hose goes in is the part of the job that protects the drain.
Where we are not certain what we are dealing with, we put a camera down first. It costs a few minutes and it avoids turning a blockage into a collapse.
The High Street food premises, the salons and the care homes around Banstead all put far more through a drain than a house does. For those we jet to a schedule rather than waiting for a failure, usually outside opening hours.
Where a grease trap is fitted, we check it on the same visit. Jetting the line downstream of a neglected trap only buys a few weeks.
A camera can only see a drain once it is clean. Run before jetting, a survey shows the blockage and little else; run afterwards it shows the joints, the falls, the cracks and any point where roots are getting in.
We do not survey as a matter of routine. On a drain that has blocked more than once it is the difference between clearing it again next winter and knowing why it keeps happening.
Cooled fat in the bin rather than the sink. A strainer over the kitchen waste. A hair trap in the shower. Nothing flushed but the three things that should be — wipes do not break down, whatever the packet claims.
Outside, clearing leaves and chalk silt off the gullies before autumn prevents a large share of the winter call-outs we attend in Banstead.
We carry jetting equipment on the van as standard rather than booking a second visit for it. If a drain has backed up and is threatening to enter the property, that matters.
If waste is rising in a gully or a downstairs toilet will not clear, stop running water anywhere in the property and call us. Every further flush adds to what already has nowhere to go.
Q: Is jetting safe on older clay drains?
A: Yes, when the pressure is matched to the pipe. Glazed clay takes jetting well; pitch-fibre needs a lighter touch. Where we cannot tell what is in the ground from the chambers, we put a camera down before the hose.
Q: How is jetting different from rodding?
A: Rods push a single obstruction along. Jetting removes it and scours the pipe wall behind it, so the drain returns to its full bore instead of a channel through the middle of the build-up.
Q: Will jetting stop the drain blocking again?
A: It removes the cause rather than the symptom, so it lasts far longer than rodding. Where a drain keeps blocking in the same spot, something structural is usually behind it and a camera survey will show what.
Q: Do you cover all of SM7?
A: Yes — Banstead village, the High Street, Nork, Tattenham Way and the surrounding SM7 roads, for homes and commercial premises alike.
