Lower-ground sink drains slowly
Describe the exact use or discharge that brings the symptom on. Leave the waste assembled and pause the relevant appliance when water escapes.
FOREST HILL · GRAVITY WASTES ACROSS SPLIT LEVELS
A sloping site does not guarantee that every internal waste pipe has a useful fall. Lower-ground rooms, long cupboard runs and later alterations can introduce flat sections, poor support or a need for a different drainage arrangement.

PLAN ACCESS BEFORE OPENING WORK
A sloping site does not guarantee that every internal waste pipe has a useful fall. Lower-ground rooms, long cupboard runs and later alterations can introduce flat sections, poor support or a need for a different drainage arrangement.
Photograph the route from the appliance or sink to the point where the waste disappears. Do not use chemical cleaner to mask a slow discharge before the visit, because the plumber needs to see the normal behaviour.

SEPARATE THE FOUR CONCERNS
Record garden-room waste rises before exiting
on its own. Keep external pipe is poorly supported on steps
separate. Add dimensions for water pools around a back door
.

Record the first wet point, timing and any nearby use without declaring a source. Contain reachable water safely and keep clear of electrical equipment.

Gravity wastes across split levels can involve joinery. For lower-ground sink drains slowly
, separate decoration work in Forest Hill from plumbing. If garden-room waste rises before exiting
suggests risk, arrange electrical review in Forest Hill for gravity wastes across split levels. Communal pipework affected by gravity wastes across split levels belongs with the party responsible in Forest Hill.

POSSIBLE PLUMBING TASKS
lower-ground sink drains slowly
For garden-room waste rises before exiting
, consider one task. Assess external pipe is poorly supported on steps
separately. Inspection sets the Forest Hill scope for gravity wastes across split levels.
Lower-ground sink drains slowly: examine waste joints, appliance hoses and fall. Confirm isolation for lower-ground sink drains slowly before examining adjacent Forest Hill pipework.
Garden-room waste rises before exiting: examine waste joints, appliance hoses and fall. Confirm isolation for garden-room waste rises before exiting before examining adjacent Forest Hill pipework.
External pipe is poorly supported on steps: examine accessible supplies and the water path. Confirm isolation for external pipe is poorly supported on steps before examining adjacent Forest Hill pipework.
Water pools around a back door: examine accessible supplies and the water path. Confirm isolation for water pools around a back door before examining adjacent Forest Hill pipework.
USE CONDITION, NOT ASSUMPTION
garden-room waste rises before exiting
Keep sound parts near lower-ground sink drains slowly
. Treat external pipe is poorly supported on steps
as a separate Forest Hill control question.
lower-ground sink drains slowly
Retain sound fittings around lower-ground sink drains slowly; replace only what lower-ground sink drains slowly implicates.
garden-room waste rises before exiting
Measure garden-room waste rises before exiting on site. Use Forest Hill dimensions when matching garden-room waste rises before exiting
.
external pipe is poorly supported on steps
Ask the Forest Hill controller to confirm isolation for external pipe is poorly supported on steps
.
water pools around a back door
Size access around water pools around a back door; agree the Forest Hill closing method before work.
BUILD THE SCOPE FROM FACTS
lower-ground sink drains slowly
affects access; garden-room waste rises before exiting
affects isolation; external pipe is poorly supported on steps
defines the final test.

POINTS TO SETTLE IN ADVANCE
For lower-ground sink drains slowly
, provide context. For garden-room waste rises before exiting
, arrange safe Forest Hill access. Leave garden-room waste rises before exiting
assembled during gravity wastes across split levels.
Lower-ground sink drains slowly needs a Forest Hill room view. Add gravity wastes across split levels, its onset and the nearest valve.
If garden-room waste rises before exiting leaks or shifts, stop using it in Forest Hill; leave garden-room waste rises before exiting untouched.
Position alone cannot prove lower-ground sink drains slowly. In Forest Hill, water may track away from lower-ground sink drains slowly.
A Forest Hill photograph may identify garden-room waste rises before exiting, but measure the part beside garden-room waste rises before exiting.
Identify the Forest Hill party controlling valves for gravity wastes across split levels. Record any effect on external pipe is poorly supported on steps.
Photograph the Forest Hill panel beside water pools around a back door. Agree finish restoration around water pools around a back door.
For lower-ground sink drains slowly, quote Forest Hill access and isolation. List labour beside gravity wastes across split levels; tie testing and exclusions to lower-ground sink drains slowly.
Operate external pipe is poorly supported on steps normally in Forest Hill. Restore the control for external pipe is poorly supported on steps; record its Forest Hill limit.
