Kitchen Plumbing Cardiff

No other room in the house copes with more water, grease and hard use than the kitchen, and its plumbing wears all of that. Plumbers Cardiff handles everything under and behind the benchtop, right across Cardiff and the streets around it, from a dripping mixer to a full renovation rough-in.

It sits inside the wider general plumbing run, so if the problem turns out to be bigger than the kitchen, the same crew keeps going. This page covers the jobs we do and how one runs.

What we cover in a kitchen

Six jobs make up most of the kitchen calls we get. Each one gets diagnosed properly rather than patched.

Taps and mixers

Leaking sink mixers, stiff tap bodies and worn spouts get swapped for quality replacements, and the isolation valves most older kitchens never had get fitted while we are already under there.

Dishwashers and filters

New dishwashers and undersink water filters get connected the right way, with the waste hose plumbed into the trap so dirty water from the machine cannot ever siphon back in.

Sink drains

A sink that empties slowly means grease and scraps have built up in the trap or the run beyond it, and a proper clear beats a supermarket bottle every single time.

Gas cooktops and ovens

Gas bayonets, cooktop changeovers and oven connections get done by licensed plumbers, and supply lines too old to feed a modern appliance get upgraded as part of the same job.

Undersink leaks

Flexi hoses, trap joints and supply lines all age out, and a slow weep inside a cupboard wrecks shelves long before anyone notices, so even small leaks get taken seriously.

Renovation rough-ins

New sinks, relocated appliances and stone benchtops all change the pipework behind the walls, and the rough-in gets planned with your other trades so nothing has to be opened twice.

What the housing does to a kitchen

The age of the housing explains most of the kitchen quirks here. Fibro and weatherboard cottages went up for the railway workshops families, brick veneer followed through the later decades, and townhouses have filled gaps since the 1980s. Three patterns come with that:

Untouched original runs

Plenty of sinks still sit where they were plumbed decades ago, on supply and drain lines that have never been opened up. Everything gets checked while we are under there anyway.

Clay drainage beyond the sink

Houses built before PVC was standard often still run earthenware lines, so a sink that keeps blocking can point at a cracked joint down the run rather than grease in the trap.

Ground movement

Reactive clay soils shift pipework over the years, which is why joints under and past the sink get a close look on every call.

None of that makes the job harder to quote. It means the diagnosis happens before the spanner comes out, and the price reflects what the pipework is actually doing.

Renovations and the gas line nobody planned for

Kitchen renos are where an older home pushes back. Two things in particular:

Gas supply

Detached homes from the mid-century decades often still carry gas piping and connections from when they were built, and a new cooktop or wall oven frequently outgrows what that line can deliver.

Drain layout

Moving the sink or adding an island bench changes the drain run underneath, and the condition of the existing line decides whether that is a simple extension or something bigger.

The gas issue tends to surface mid-renovation, which is the worst moment to find it. So the run gets assessed when we quote, and any upgrade gets scoped into the job with the rest of the plumbing.

That way it never ambushes the budget a week before the benchtops arrive. The gas fitting page covers that side in more detail.

When it is not really a kitchen problem

Some kitchen calls turn out to belong to a different run, and those hand over cleanly:

Kitchen plumbing questions

Why does my kitchen sink keep blocking?

Grease and food scraps settle in the trap, but repeat blockages in older homes often point at cracked clay further down letting roots in. We clear it and find the cause.

Can you connect a dishwasher to an older sink setup?

Yes. Older kitchens often lack isolation valves and proper trap connections, so we fit them while connecting the machine and plumb the waste hose so it cannot be pulled back into the machine.

Do you handle the plumbing side of a kitchen renovation?

We do. Sink relocation, new supply lines, drainage rough-ins and appliance connections all get planned alongside your other trades, so the walls never have to come apart twice.

Who does the gas connection for a new cooktop?

Licensed plumbers on the same trucks do it. If the existing gas line cannot feed a modern appliance, the upgrade gets scoped and quoted into the one job.

Why is the cupboard under my sink always damp?

Usually a weeping flexi hose, trap joint or supply line. Slow drips quietly rot the shelf and the cupboard floor, so it is worth a proper look rather than a towel on the shelf.

What does a kitchen plumbing call cost?

The call out costs nothing. You get a clear quote before any work begins, and you either approve the price or we pack up and leave, no charge.
