Network signs
When the network isthe problem.
A building gives warnings long before it overflows, but nobody joins them up.
01
Complaints from several flats
Two or three flats report slow drains or a smell in the same week, and each one calls a different technician. Putting them together is what shows the shared line is the cause, not one flat.
02
One chamber floods on a cycle
One particular chamber floods, gets cleared, and floods again. A repeat at the same point means a bad fall, a sag or settled deposit at that spot, not coincidence.
03
It gets worse in summer
A building copes in winter and stops in summer. Use rises, and heat lets grease settle heavier on the pipe wall, so a line that was only just coping stops coping at all.
The service in short
Network work, short.

How a visit runs
A maintenance visit,step by step.
The same route on every visit, so one can be compared with the next.
We walk the whole run
Every chamber and manhole is opened, from the first point in the building to the last one before the network or the pit, and the channel level at each is noted.
We find the weak point
The difference between one level and the next is what shows where the run has narrowed. The point just before the level rises is where the work goes, not across everything.
We clear and lift the deposit
The line is rodded at that point and what comes loose is lifted out rather than pushed further down, and the channel and benching are washed in any chamber holding deposit.
We set the next interval
The state of the building sets how often the visit repeats, not one fixed calendar for every building. We tell you what we found and agree the next one with you.
Why on a schedule
A contract versusan overflow call.
A building's network is not one pipe, it is a chain. Flat branches feed vertical stacks, the stacks feed a horizontal line under the building, and that line passes through inspection chambers one after another until it reaches the public network or the pit. Every chamber is a window onto one section of the chain, and that is what makes it useful.
The difference between a contract and an overflow call is that a contract looks at the chain while it is still working. Open a chamber and find a shallow stream in the channel and that section is sound. Open the next one and find the level higher, and the narrowing is between those two points exactly, in time to work on it.
In residential blocks the biggest cause is kitchen grease. One kitchen puts a little oil down each day; ten kitchens on the same stack put down ten times as much, and all of it cools against the same horizontal pipe wall under the building. It gathers most where the line changes direction, because that is where the flow slows.
Complexes add another cause: restaurants and cafes. A grease trap that is not emptied on a schedule passes everything to the shared line, and the problem stops belonging to one unit and starts belonging to the building. That is why a scheduled visit includes the outlet point of every unit, not only the main run.

Manager questions
Asked by buildingmanagers.
Someone who can open doors, passages and access points, and the list of complaints residents have sent you. Those complaints halve the work, because they tell us where on the run to start.
It depends on the number of units, whether food outlets share the line, and the state we find on the first visit. We suggest the interval after walking the run, not before.
The work happens in chambers and manholes outside the units, and the clean water supply is untouched. The only people who need warning are the units on the line being worked, so they run less water while we are on it.
It changes a lot. The outlet from the unit needs checking on its own and the grease trap has to be working, otherwise grease reaches the shared line and the problem becomes the building's, not the unit's.
We start by looking and use the gentlest method, rods turned by hand rather than anything forceful. If a sag or a crack shows in one length we stop there and say so, because pushing through a broken pipe makes the break bigger.
