Emergency Plumber Knocklyon
A pan connector gives way in an Idrone bathroom just after the school run, and water starts dripping through the kitchen light. Later that evening, a coffee shop in Knocklyon Shopping Centre finds its hand-wash sink leaking across the tiles. When either happens, an emergency plumber in Knocklyon is one phone call away, day or night.
We work right across the parish, from Knocklyon Road and Scholarstown Road to the newer estates beyond the M50 along Ballycullen Road.
Homeowners, tenants, landlords, apartment residents, management companies, pubs, bars, restaurants, cafés, coffee shops, schools, clubs, clinics and care homes all rely on us. Whoever is calling, a text or email confirms our hourly charge first, and only then do we drive over.

Emergency Plumber Knocklyon Between the Dodder and the M50
Knocklyon sits on the south bank of the River Dodder, with Templeogue across the water. Firhouse lies to the west, and Rathfarnham and Ballyboden to the east.
Its first estates went up in the 1970s around the old village and Knocklyon Castle. After that, building spread south and west until the M50 split the area in two. The newest homes now stand on the far side of junction 12.
As a result, a five-minute trip may move us from 1970s copper to modern plastic pipe and pressurised hot water.
Our van carries fittings for both, so we can usually finish the repair on the first visit.
Knocklyon Road and Old Knocklyon Road
Old Knocklyon Road keeps a handful of older cottages and bungalows, while Knocklyon Road carries traffic past the church, the schools and the shopping centre.
In the older houses, lead or early copper may still run from the boundary box to the kitchen. Where we find lead, we advise replacing that section with modern pipe, because it corrodes and can affect your drinking water.
Similarly, the original stopcock is often buried at the back of a press or under the stairs.
We check it on every job, and any valve that has seized gets swapped for a quarter-turn one you can close in seconds.
Emergency Plumber Knocklyon on Scholarstown Road and Firhouse Road
Scholarstown Road links Knocklyon with Ballyboden and Rathfarnham, and Firhouse Road follows the Dodder towards Templeogue Bridge. Both are busy, so homes and businesses along them often need a morning or evening slot.
Houses on these routes typically date from the 1970s and 1980s. Many have had kitchens extended to the rear, which moved the sink and washing machine away from the original waste pipe.
Sometimes those longer runs lack a proper fall, so they block or leak at a joint. Whenever that happens, we can re-lay the section to the correct gradient.
Idrone, Beverly, Coolamber, Knockaire and Knockcullen
Idrone, Beverly, Coolamber, Knockaire and Knockcullen are among the longest-established estates in Knocklyon. Most homes there are semi-detached, with the hot press upstairs and a cold storage tank under the roof.
After forty years, the ballcock in that tank can stick. Consequently, water may pour from the overflow pipe on the gable, or the tank may run dry while the taps splutter.
Meanwhile, the compression joints in the hot press can start weeping onto the hot press floor. Brown stains on the landing ceiling are usually the first sign.
We replace float valves and reseal or remake joints.
Orlagh, Templeroan, Woodfield, Dargle Wood and Scholarstown Park
Further south, estates such as Orlagh, Templeroan, Woodfield, Dargle Wood and Scholarstown Park followed during the 1980s and 1990s.
Here, plastic push-fit pipe appears alongside copper, especially where later owners added en-suites or converted the attic. A push-fit joint that was never fully seated can hold for years before it lets go.
Often the only clue is a ceiling that bulges below a bathroom. In such cases, we open the smallest area possible, rebuild the joint and test it under full pressure.
Garden taps on side passages are another weak spot. Where one has split in the frost, we fit a frost-resistant tap with an indoor isolating valve.
Emergency Plumber Knocklyon for Woodstown, Glenvara, Castlefield and Glenlyon
West of the motorway, Woodstown, Glenvara, Castlefield, Glenlyon and Dalriada contain newer houses, duplexes and apartments.
Many of these homes have mains-pressure hot water, along with multilayer or plastic pipe. When a pressure relief valve starts to discharge, the tundish in the hot press will drip or hiss.
Ignoring it risks a flooded floor, so switch off the immersion and ring us.
We find the cause, replace the faulty valve and check the rest of the unit before leaving.
Burst, Leaking and Frozen Pipes
A burst pipe can release hundreds of litres an hour. Therefore, close the main stopcock before anything else, then call.
Once on site, we find the break, cut out the damaged length and join in new pipe of the correct type. Where a run has corroded along its length, we recommend replacing the whole section rather than patching it twice.
In winter, roof spaces, garages and pipes on outside walls are most at risk. If a tap stops flowing during a hard frost, keep the stopcock closed until we arrive, since a thaw can open a hidden split. Frozen or burst, it is a job we handle every winter.
We also install new pipework for extensions, utility rooms and relocated kitchens. You can read more under burst and leaking pipe repairs.
Toilets, Cisterns and Urinals
A toilet that keeps refilling is one of the most common calls we get in Knocklyon. A push button that sticks or a pool of water around the pan are just as frequent.
Usually the culprit is a tired fill valve, a flush seal that has perished or a cracked pan connector. Occasionally, the close-coupled bolts beneath the cistern have rusted through.
Replacing those parts is quick, and a toilet that is past saving can be swapped for a new one on the same day.
For schools, clubs, pubs and offices, we also unblock and replace urinals, and repair flush controls and concealed cisterns. See our toilet repairs and replacement service for more.
Taps, Flexible Hoses, Stopcocks and Valves
Beneath a Knocklyon kitchen sink, you will usually find a mixer tap on two braided hoses, plus feeds for the dishwasher and washing machine.
Those braided hoses age quietly. After ten years or so, the outer mesh can rust, and the inner tube may then burst with no warning at all.
We renew tired hoses, fit isolating valves where none exist and repair or replace dripping taps. In addition, we replace stopcocks that no longer close properly.
Our tap repair and replacement page explains the work in more detail.
Soil Pipes, Waste Pipes and Traps
Soil and waste plumbing is part of our everyday work. On older Knocklyon houses, the soil stack is often cast iron, whereas later homes have plastic stacks that can crack where a bracket has failed.
If a stack or branch is leaking, we remove the damaged length and join in a new one. When the whole stack has deteriorated, we replace it.
Under sinks, baths, showers and basins, we renew leaking traps and split waste pipe too.
Whenever an extension moves a bathroom or kitchen, we lay new waste pipework at the right fall. Local blockages in toilets, sinks, baths and urinals can usually be cleared on the same visit.
Emergency Plumber Knocklyon for Water Heaters and Electric Showers
Hot water problems in Knocklyon usually trace back to the immersion in the hot press or an undersink or oversink water heater.
A leak from the immersion boss or a heater that no longer warms up needs attention. We repair what can be saved and install a new heater when that is the better option.
Electric showers are repaired or replaced, depending on what we find.
More details are on the water heater installation and electric shower replacement pages. Since we are not gas installers, boilers and gas appliances should go to a Registered Gas Installer.
Booster, Well, Sewage and Submersible Pumps
Upper floors in duplexes and apartment blocks often depend on a booster pump. A few homes on the fringes of the parish still draw from a well.
A pump that short-cycles, hums without delivering water or leaks at its unions needs looking at before it fails completely. We repair and replace booster, well, sewage and submersible pumps, together with their valves and pipework.
Frequently, a noisy pump turns out to be a failed pressure vessel or a stuck non-return valve, which is a cheaper fix.
Our pump services page has further information.
Commercial Storage Water Tank Replacement
Storage water tank replacement is a major part of what we do, and most of it is commercial. Schools, sports clubs, care homes, apartment blocks, hotels and business premises all rely on large cold water tanks.
With age, those tanks can crack, sag or leak at their connections. Moreover, an open or damaged lid lets debris and insects reach the stored water.
We remove the old tank, install a new one with fresh valves and connections and restore the supply with minimal downtime. Homeowners can also have a worn attic tank replaced.
For a tank that only needs a clean, see storage water tank cleaning.
Emergency Plumber Knocklyon for Shops, Pubs and Cafés
Knocklyon Shopping Centre and the parades nearby hold a supermarket, a pharmacy, takeaways, restaurants, cafés and coffee shops. The local pubs and bars are never far away.
For any of them, a leaking sink, a toilet out of order or a water heater that has failed can stop trade. As your commercial plumber, we arrive before opening time or after closing, whichever suits the business.
Typical jobs include hand-wash and prep sinks, water heaters, WCs, urinals, taps and supply pipework.
Hair salons, dental practices, GP surgeries and physiotherapy clinics book us as well. Whatever the premises, we can be there quickly.
Schools, Sports Clubs and Care Homes
St Colmcille’s schools and Gaelscoil Chnoc Liamhna teach hundreds of pupils every day. Nearby, Ballyboden St Enda’s GAA Club, Knocklyon United and the community centre host teams, classes and events all week.
Toilets, urinals, showers and taps in buildings like these work hard. Afterwards, they sit idle over holidays, which is when seals dry out and valves stick.
We fix what has failed and, where it helps, carry out planned checks before term begins. Principals and club secretaries can keep our number on speed dial for match days and exam weeks.
Nursing homes, care homes and clinics across Dublin 16 cannot wait for hot water or a working bathroom. Such calls always go to the top of our list.
Commercial Plumber and Industrial Plumber for Local Businesses
Hotels, guesthouses and B&Bs within easy reach of the M50 need every guest bathroom working. So when a shower fails or a tap leaks, we aim to have the room back in use before the next check-in.
Petrol stations and forecourt shops on the roads around Knocklyon call us about customer toilets, deli sinks and staff facilities. Gyms and clubs, meanwhile, need their changing-room showers running.
We also work as an industrial plumber for offices, factories, warehouses and business units in the surrounding business parks. That work covers rising mains, pumps, canteens and washrooms.
Businesses can settle invoices by bank transfer.
Emergency Plumber Knocklyon for Homes, Tenants and Landlords
Knocklyon is mostly residential, so domestic call-outs make up much of our work here.
Homeowners call us for everything from a dripping tap to a new electric shower. Tenants can ring us directly, and we keep the landlord or letting agent informed from start to finish.
For landlords, we contact the tenant, agree a time, carry out the repair and send photos with a short report. Management companies overseeing duplex and apartment developments book us for shared risers, plant rooms and booster sets too.
Between lettings, testing the stopcock and looking over the attic tank and cistern valves can prevent an expensive claim later on.
Saniflo Installation and Unblocking
Garage conversions, basement rooms and downstairs toilets in Knocklyon often sit too far from the soil stack for a normal connection. In that situation, a Saniflo macerator is the practical answer.
We supply and install the complete unit, lay its small-bore discharge pipe and hook up the WC, basin or shower. We also unblock Saniflo units that have jammed.
Nearly every blockage is caused by wipes or sanitary items flushed by mistake. So, while you wait, please stop using the toilet and every fixture that empties into the macerator.
Please note that we do not repair Saniflo motors.
What to Do While You Wait
Taking a few steps before we reach you can limit the harm to your home:
- Turn off the water using a local isolating valve or, failing that, the stopcock. A stiff valve should never be forced.
- Keep away from wet electrics. Only touch the consumer unit if you are standing on dry ground.
- Open the cold taps downstairs to empty the pipes of remaining water.
- Catch drips with buckets and towels, but stay clear of a ceiling that is sagging.
- Photograph the damage before you clean up, for your insurer.
Uisce Éireann also publishes advice on finding and fixing leaks.
How a Knocklyon Call-Out Works
Call or text us your Eircode, along with a line or two about what has gone wrong. A photo helps us bring the right fittings.
Next, our hourly rate comes to you in writing, together with a realistic arrival time. With your go-ahead, the van leaves straight away.
On arrival, our priority is to stop the water. Then the fault is traced and repaired with stock from the van. Should an unusual part be needed, we make the system safe and return once it is in stock.
Finally, we tidy up and explain what failed. Evenings, nights and weekends follow the same process, which the 24/7 emergency plumber page sets out.
Emergency Plumber Knocklyon Prices and Payment
Billing is hourly, and that rate reaches you by text or email before we leave for Knocklyon.
Sometimes a clear photo allows us to give a rough estimate. That figure is a guide only, because the final bill depends on the time actually spent on site.
Old or corroded fittings take longer to deal with. Likewise, time spent parking and reaching the fault counts as time on site. Near the schools and the shopping centre, spaces get tight at drop-off and pick-up. Please tell us where the van can stop, any gate or fob codes and your apartment number.
Weekdays during office hours cost least, while evening, night, weekend and bank holiday work costs more per hour.
- Households: pay by card or in cash when the job is done, or via a payment link
- Businesses, schools and clubs: the same options, plus bank transfer
Every job is covered by full insurance, we clean up after ourselves, and we can prepare a report for your insurer on request.
