Plumbing and drainage problems in Crystal Palace
Plumbing faults do not all present in the same way. A damp patch may point to a concealed leak, while slow drainage may be limited to one fitting or affect more of the waste system. We use the location and pattern of the symptoms to narrow down what needs to be checked.
Review our plumbing services and drain-unblocking information for more detail.

Visible water leaks
Assessment of water escaping from accessible pipes, joints, taps, toilets or fittings.

Suspected hidden water loss
Help where dampness, water-meter movement or pressure changes suggest a concealed leak.

Taps, toilets and fittings
Problems with fittings that leak, run continuously, fail to flush or no longer work correctly.

Blocked sinks, baths and showers
Support for an outlet that drains slowly, will not clear or starts to back up.

Internal waste-pipe problems
Assessment when a trap or accessible internal waste connection appears to be affected.

Urgent water leaks
Call when escaping water could cause further damage and explain whether the supply can be isolated.

Boiler fault indication
Note the exact display code and whether heating and hot water are both affected.

Heating will not start
Describe whether the system starts briefly, stops unexpectedly or does not respond.

Cold or intermittent hot water
Explain whether the problem is constant, intermittent or limited to a particular outlet.

Cold or uneven radiators
Help with radiators that remain cold, make unusual noise or heat differently from the system.

Heating leaks
Assessment of visible water around radiators, valves and accessible heating pipework.

Heating controls
Tell us which control is affected and whether the system responds to normal settings.

Pressure changes
Mention recent loss or increase of system pressure and any visible signs that appeared with it.

Heating service guidance
Use our heating services page for general faults or emergency boiler repair for urgent problems.

Blocked kitchen sink
Stop using the outlet if water is backing up and explain whether other fixtures are affected.

Slow bath or shower
Describe how quickly water builds up and whether the problem has become worse over time.

Multiple affected drains
More than one slow or blocked outlet can help identify the part of the waste route involved.

Recurring blockage
Tell us what was previously done and how soon the drainage symptoms returned.

Safe drainage first steps
Avoid combining chemical products and stop using an overflowing or backing-up fixture.

From symptoms to the appropriate service
Identify whether the main issue is plumbing, drainage, heating or hot water. For a leak, isolate the supply only if the valve is accessible and safe. For a blocked drain, stop using the affected fixture and avoid mixing drain-cleaning chemicals. Do not remove a boiler casing.

Recommend very highly!Posted on Google Serena ReidTrustindex verifies that the original source of the review is Google. Came home from on holiday on 03/01/26 to the boiler not working - not heating or hot water - on one the coldest days of the winter. Was calling round desperately to find emergency plumber at 8pm on a Saturday. Despite calling multiple plumbers, none could come until the Monday...Then there was Alex! He came round on that Saturday night, found the problem and made a plan to replace the broken part. He was AMAZING! He was upfront about costs, timings, issues and part sourcing. Within 72 hours (part sourcing and error code issues that, were unrelated to Alex, were an issue) We had our boiler back working. Very grateful to Alex, who was so in demand and worked like trooper, would 100% recommend himPosted on Google Jasmine KershawTrustindex verifies that the original source of the review is Google. Can’t recommend highly enough! Alex arrived quickly and fixed our leaking water heater in a jiffy. He gave some great, honest advice and charged exactly what he said he would (a very good price). Efficient and friendly - will definitely be saving his number for future plumbing crises.Posted on Google Leo JasminTrustindex verifies that the original source of the review is Google. Alex sorted out all the problem in my boiler, great service and friendly, highly recommended for boiler and heating problems👍

FAQs
Can you help with a blocked drain in Crystal Palace?
Call and explain which fixture is blocked, whether other drains are affected and whether water is backing up. Stop using the affected outlet until the cause has been assessed, and avoid combining chemical drain products.
What details help with a boiler fault?
Note the make if visible, the exact display code, whether heating and hot water are both affected, and whether there is a leak or pressure change. Do not remove the casing or reset the appliance repeatedly.
What should I do about a suspected hidden leak?
Check whether the water meter continues to move when known outlets are off, if that can be done safely. Record visible dampness or changes in pressure, but avoid opening walls or floors before the source is assessed.
