A slow-draining shower or a toilet that won't flush can turn a calm morning in Sanur into a stressful one. Most villa blockages come from hair, grease, or small objects that build up over months of use. Below I'll walk you through spotting the problem, finding where the clog sits, what you can safely do yourself, and when proper equipment is needed.
Signs Your Drain Is Blocked
The first warning is usually subtle. Water drains noticeably slower than before, or you hear gurgling from another fixture while running the tap. In older Sanur villas with clay or early-PVC pipework, even a partial blockage backs up quickly because those pipes are narrower than modern standards.
More serious signs include water pooling around the floor drain, sewage odour near the bathroom, or multiple fixtures slowing down at once. If you smell raw sewage rather than just stale water, stop using the area and ventilate the room immediately.
- Water takes more than 30 seconds to clear from a basin or shower tray
- Gurgling sounds from a different fixture while you run water elsewhere
- Foul, sulphur-like smell near the toilet or floor drain
- Two or more slow-draining points in the same bathroom
- Standing water on tile after a normal-length shower
Where Is the Blockage?
Before grabbing any tool, work out whether the clog is local or in the main line. Run water into one fixture only — say the kitchen sink. If it clears fine but the bathroom shower stays slow, the problem is likely in that branch pipe or its P-trap. If every fixture in the villa drains poorly simultaneously, the blockage sits further downstream: the main soil stack or the external run heading toward your septic tank.
Sanur villas discharge into individual septic systems rather than a municipal sewer. The pipe between your last fixture and the tank is a common choke point, especially if tree roots have crept in over the years or solid waste has settled in a low spot. Lift the access manhole (usually under a concrete lid in the garden). If the liquid level inside is higher than usual and not dropping after a flush, the outlet pipe may be restricted.
Quick test: pour a bucket of warm water into the toilet bowl while watching the floor drain in the same bathroom. If the floor drain bubbles up, the shared branch between those two points is blocked.
Send me a quick photo of the affected fixture or manhole on WhatsApp and I'll let you know whether this is something you can clear yourself or if we need to bring equipment out.
Using a Drain Snake (Auger)
For a local clog in a sink, shower, or toilet branch, a hand-cranked drum auger is usually enough. You'll find them at hardware stores along Jalan Sanur or in Legian. Choose one with at least 5 metres of cable so you can reach past the P-trap.
Work through these steps in order:
- Remove the P-trap or cleanout cap first so the snake enters open pipe, not the trap bend
- Feed the cable gently until you feel resistance — that's the clog
- Crank clockwise to hook or break up hair and grease, then pull slowly
- Repeat two or three times; flush with warm water to confirm flow
- For a toilet use a closet-specific auger and avoid pushing the flange off the wax ring
Hydrodynamic Jetting
When a snake can't clear the line, or when the whole villa drains poorly and the septic inlet is restricted, hydro-jetting is the next step. A high-pressure pump sends a lance down the pipe and blasts out grease, scale, root intrusions, and settled solids at pressures well above what any household hose achieves.
In Sanur this service is common for villas with long external runs to the tank, especially after the rainy season when leaf litter and silt wash into open manholes. A good technician will inspect the pipe with a camera first so you see exactly what they're clearing before the jet starts.
Safety note: if you smell methane from an open manhole or in a confined utility room, ventilate immediately and do not flip any electrical switch nearby. Leave the space and call a professional rather than working in it yourself.
Prevention: Keeping Your Lines Clear
A little routine care saves a lot of stress later. The salty sea air here is mildly corrosive over years, so exposed outdoor pipe joints can weep and let soil in. A quick visual check of visible external runs twice a year — dry season and just before the rains — catches small leaks before they become blockages.
- Fit hair catchers on every shower drain; clean them weekly during humid months when hair sticks more
- Wipe cooking oil off pans with paper towel instead of rinsing it down the sink — it solidifies in cooler pipes
- Flush only single-ply toilet paper; no wipes, cotton pads, or sanitary products even if labelled 'flushable'
- Run a bucket of warm water through each floor drain monthly so standing water doesn't evaporate and leave mineral film
- Have your septic tank pumped out on schedule based on household size; a full tank pushes sludge back toward the inlet pipe
- Keep young trees away from external pipework or install root barriers at planting time
Questions
How do I tell if my septic tank is full versus a simple pipe clog?
If every fixture drains slowly at once and the liquid level in the manhole stays high after flushing, the tank is likely full or its outlet is restricted. A single slow fixture usually points to a local branch clog. When unsure, send a photo of the manhole interior on WhatsApp and I'll tell you which it looks like.
Can I use chemical drain cleaners instead of calling someone?
I'd avoid them in any villa with a septic system. The harsh acids and caustics kill the bacteria that break down waste in your tank, and repeated use corrodes older PVC or clay joints. If the clog is hair or grease, a snake or hydro-jet clears it without that collateral damage.
What should I do right now while waiting for help?
Stop using all water fixtures in the affected area. Mop up standing water (not a wet-dry vacuum near electrics). Open windows for ventilation. If there's any gas smell near an open manhole, leave the space entirely and call before doing anything else.
I'll reply with what's needed, a price and when I can come.
