Drain & Deep Clean

A proper drain-and-clean is preventive maintenance wearing work gloves: purge the lines, flush the mineral, rebuild the chemistry for the water you actually have.

Drain & Deep Clean — how we work it

Around here a drain is not just fresh water — it is the one chance to undo what dissolved rock has been doing since the last one. Our service runs the full sequence: a purge product through the old water to strip biofilm from the plumbing, full drain, mineral flush through the heater path, filters soaked or replaced, then a refill balanced against a hardness test of your actual tap, not a statewide average.

Done on a schedule, this one visit is why our regulars almost never meet our heater department. Skipped for a year or two, the same minerals show up later wearing a much bigger invoice.

What the symptom usually means

Cloudy days after a refill

Filters past saving or chemistry set for softer water than yours. Both are fixable on the spot.

Chalk ring at the waterline

The visible edge of what is also coating the element and the jet passages.

A smell chlorine won't kill

Biofilm in the lines. It laughs at sanitizer and surrenders to a purge.

Filters grey after rinsing

Mineral baked into the pleats. Rotation or replacement — rinsing is over.

The procedure

  • Line purge before the drain, every time
  • Heater-path mineral flush included
  • Filters assessed honestly — soak, rotate or replace
  • Hardness tested at your tap, chemistry set to match
  • Equipment bay eyeballed while the panel is off

Straight questions

How often should this be done here?
Quarterly is the honest answer for most tubs on local water; heavy use shortens it. We will tell you what your usage pattern actually needs.
Can you rescue water without draining?
Sometimes — a sequestering course and rebalancing. Past a certain mineral load, draining is cheaper than chemicals.

WO-1454

Smell that outlived the chlorine

Biofilm in the plumbing. Purge product, full drain, refill — gone.
