Bathroom Plumbing
in Pietermaritzburg
Toilets, basins, showers and baths, replaced where they stand or moved, with the drainage rules settled before the tiles go down.
Request a call-outBathroom plumbing in Pietermaritzburg comes in two kinds: replacing a fitting where it stands, and moving or adding one. Msunduzi's by-laws treat the second as drainage work, needing written permission, notice and an inspection before it is covered. Your quote says which kind of job it is, and what that needs.
Six bathroom jobs, and the rule behind each
What the work involves, and the one thing worth knowing before it starts.
- Toilet replacement
- The work: the new pan on the old outlet, a new pan connector and a cistern valve.
- Worth knowing: SANS 10252-1 calls for an isolating valve on the pipe feeding the cistern, right next to it.
- A toilet that runs or rocks
- The work: a flush valve washer, a float valve set too high, or a loose pan bedded down again.
- Worth knowing: Msunduzi's by-laws allow no reduction on the bill for water lost inside your installation. The leak detection page has the colouring test.
- Basins and vanities
- The work: the mixer, the waste and trap, and the connectors to the supply.
- Worth knowing: SANS 10400-P puts the tap outlet at least 20 mm above the level at which the basin would overflow.
- Showers
- The work: a mixer and head chosen for the pressure your house gets, and the waste and trap below.
- Worth knowing: a hand shower on a hose has to be protected against back-siphonage under Msunduzi's by-laws.
- Baths
- The work: the waste, overflow and trap, the mixer, and the supply behind the bath panel.
- Worth knowing: SANS 10252-1 puts the hot tap on the left, and a single-lever mixer's hot position to the left too.
- Moving or adding a fitting
- The work: new waste, soil and supply pipes to the new position.
- Worth knowing: that is drainage work, with permission, notice and an inspection before it is covered. The section below explains.
Swap a fitting or move one: where Msunduzi draws the line
Replacing a toilet where it stands is upkeep. Moving it, or adding a shower, is drainage work, and the municipality wants to know before it starts.
Msunduzi's Water Services By-laws count a bathroom's drains, waste pipes and sanitary fittings as drainage work. Section 71 says nobody may construct, alter or add to a drainage installation without the Council's written permission, and that the work may not begin until two clear days after written notice of when it will start. Before any part of it is covered or made hard to inspect, the Council has to inspect and approve it.
Replacing a worn fitting in the same place sits on the other side of that line. The National Building Regulations need no plans or approval for a repair made necessary by ordinary wear and tear or normal upkeep, and the by-laws need no permission to repair or replace an existing pipe or water fitting. A new toilet on the old outlet, or a new mixer on the old supply, is a replacement, not a change to the drainage.
- Basin trap: 32 mm, holding a 40 mm water seal on a two-pipe system.
- Shower trap: 40 mm, with a 40 mm seal on a two-pipe system.
- Pan connector: falls to the soil pipe at no less than 1 in 40, and may not be the concertina type.
- Isolating valve on the pipe to the cistern, next to it.
- The drain: no smaller than 100 mm across.
Moving a toilet across the room, adding a shower or turning a bath into a walk-in shower changes the drainage itself, and that is what the rules care about. The pan connector has to fall towards the soil pipe at no less than 1 in 40, every fixture drains through a trap that holds a water seal, and the drain may not be smaller than 100 mm. Where plans are needed, the drainage drawing shows each sanitary fixture and every soil, waste and vent pipe.
Skipping the step costs more later. The Council can serve notice on unlawful drainage work and, if the owner does not act, carry out the alteration itself and recover the cost, and since a 2019 amendment a breach of the by-laws can carry a fine of up to R1 million. The by-laws also reserve installation work, other than repairing or replacing what is there, for a qualified plumber: someone who has passed the Department of Labour's plumbing trade test.
So a bathroom quote that moves anything says so: which fittings move, the drawing if one is needed, the notice to the Council, and the inspection before the floor and walls are closed. The tiler comes after the inspection, not before it.
Replace in place and it is upkeep. Move a fitting and it is drainage work: permission first, and the inspection before anything is tiled over.
Showers and mixers for the pressure you actually get
Msunduzi has been reducing pressure since September 2025, and its by-laws promise none in particular. Fittings differ in what they need.
The by-laws say that supplying water is no undertaking to keep up an uninterrupted supply or a specific pressure, and they add that the Council does not undertake to keep enough pressure for flush valves. A fitting that worked well at the old pressure can struggle at the new one.
Under the same by-laws, every tap and water appliance has to be marked, or come with a leaflet, giving the pressure range it is designed for and its flow at 20, 100 and 400 kPa. Read it before you buy a shower for a house on reduced pressure. For a figure to compare it with, an owner can apply to the Council, for a fee, to have the pressure at the property measured over a period.
Single-lever mixers need one thing more: balanced pressure. Cobra's datasheets quote SANS 1480, under which all single-lever mixers are designed to run on balanced pressure, and SANS 10252-1 defines that as hot and cold arriving within 20% of each other. Geyser makers such as Kwikot and Ariston show a balanced cold-water outlet on the geyser's pressure control valve, and taking a mixer's cold supply from there keeps the two sides matched.
What fittings are designed for
- Standard shower head: 15 litres a minute at 20 to 50 kPa.
- Water-saving shower head: 10 litres a minute at 50 to 100 kPa.
- Aerated basin mixer: 50 kPa.
- Cistern float valve: 100 kPa, and it can work at less.
- High-pressure flush valve: 150 to 200 kPa.
Design pressures from SANS 10252-1 (2012 edition), Table 3, which apply where the maker publishes no figures of its own.
Check a shower's marked pressure range against what your house gets before you buy it.

Bathroom plumbing questions
Cost first, then permission, pressure and the fittings themselves.
Toilet replacement in Pietermaritzburg: what does it cost?
Less when the new toilet fits the old outlet, more when it does not. A pan whose outlet sits in a different place, a concertina-type pan connector (which SANS 10400-P does not allow) or a floor that needs making good all add to the job.
On the quote: the pan and cistern if we supply them, the pan connector, the cistern valve and an isolating valve, and the labour, each on its own line.
How do plumbers charge per point?
A point usually means one connection: a water supply or a waste for one fitting. Pricing per point is quick, but it can hide the pipe runs between points, and on a moved fitting those runs are most of the work. On our quotes every fitting and every pipe run has a line to itself, which lets you count the points and set the two prices side by side.
Do I need permission to move a toilet or add a shower?
Yes. In Msunduzi, adding to or altering a drainage installation needs the Council's written permission and two clear days' notice before work starts, and the new work is inspected before it is covered. A new toilet on the existing outlet is a replacement rather than an alteration. We tell you which yours is when we quote.
My shower has been weak since the water cuts. Is it the shower?
Not necessarily. Msunduzi has been reducing pressure since September 2025, and a shower head designed for higher pressure shows it first. Compare the pressure range printed on the shower's packaging with a reading taken at the tap. If the reading is fine, look at the shower itself: a clogged head or a worn mixer cartridge can cut the flow too.
Why does the hot water take so long to reach the basin?
The cold water standing in the pipe has to run out first. SANS 10252-1 limits the pipe from a geyser to a tap to 4 litres, and its own worked example is a basin at the end of a 12 m pipe running 6 to 12 litres to waste before the water is hot. A shorter run fixes it, or for a far bathroom, a second geyser close by (see geyser installation).
Can I have a flush valve instead of a cistern?
Only where the pressure is reliably high. SANS 10252-1 designs a high-pressure flush valve for 150 to 200 kPa, against 100 kPa for a cistern's float valve, which can work at less. Msunduzi's by-laws state that the Council does not undertake to keep enough pressure for flush valves, so on a supply that is being turned down, a cistern is the safer choice.
Can braided hoses be used for every connection?
No. SANS 10252-1 allows flexible connectors only to taps and fittings that can be reached for maintenance, requires them to comply with SANS 1808-5, and does not allow them in-line or on a geyser. Under a basin or behind a toilet, with an isolating valve within reach, they are allowed.
What happens to the tiles when a pipe is moved?
The quote shows where walls or floors are opened and how they are closed. If new tiles are needed, it says whether they are part of the job or left for your tiler, and either way the new drainage is inspected before anything is tiled over it.
Often part of the same job
The kitchen on the other side of the wall, a leak behind the tiles, or a geyser for a far bathroom.
