Purifier installs, quartz core drilling and handover hole plugs: access and preparation
Purifier installs, quartz core drilling and handover hole plugs is planned around the outlet that is already there. A washer, a hose, a siphon or a like-for-like tap on the same point is maintenance. Moving the waste, adding a water point, or opening a concealed riser is a PUB licensed plumber, and hacking the floor or wall for that new point is an HDB renovation permit through V On Construction.
The price moves with access, not with a slogan. An exposed fitting under a basin is a shorter visit than a concealed cistern, a ceiling tank, or a thread that has snapped inside the wall. Condo water shutdowns and HDB noisy-work hours can split the job across a slot the building allows. Parts you already bought are labour only when the thread and the seat match.

Plan Purifier installs, quartz core drilling and handover hole plugs
Isolate the stopcock or the heater switch before any fitting is loosened.
Photograph the existing joint so the replacement can match the thread and the outlet.
Do the repair on the existing point. Do not chase a new pipe unless a licensed plumber is on the job.
Run water, check the ceiling below if the bathroom is over another room, and wipe the joint dry.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Approval | Town Council hours for noisy work. An HDB permit only if the layout or a hack changes. | MCST by-laws, a water-shutdown window, and a deposit if the by-law asks for one. | No HDB permit. A new sewer run or a structural chase is still PUB or BCA, not a handyman visit. |
| Water | Like-for-like on the existing outlet stays maintenance. | The same rule, plus the building may shut the riser for a short window. | Long runs, pumps and tanks need the plumber to see the plant, not only the tap. |
| Access | Service yard and bathroom are usually reachable the same day. | Lift booking and protection of common areas come first. | A roof, a gutter or an external pipe may need safe access before anyone climbs. |
