SIX7 PLUMBING
SIX7 Plumbing Drinking Water Purification Colombo
Under-sink RO/UV staged correctly — pre-filter first, because chlorine kills membranes — with TDS tested in front of you, before and after.
The staging is the whole job: sediment pre-filter, carbon, then RO or UV, with the drain line aligned so the reject water goes somewhere sane. Skip the pre-filter and the membrane dies on chlorine in a season. We TDS-test before and after, in front of you, numbers not promises, and hand over the cartridge schedule with supply cartridges at markup.
Honest lead-time note: home Pure-type imported units are rare now and some take at least a month to source. We quote what's available this week versus what you specifically want, and you choose — office water points and multi-point setups get quoted under commercial.

6-Month Workmanship Warranty
"Any purifier makes water safe."
Wrong system for your water type wastes money and doesn't protect you.
Filtration stages mean nothing without a measured inlet — we match the cartridge set to what the test shows, not to the box.
If your purifier hasn't been serviced in 12 months, the filters are likely dead. Get them checked.
