Kitchen Plumbing & RO Lines
Kitchen Plumbing in Dehradun
Sink, RO drain, gas-safe spacing and silent-flow CPVC — kitchens that don't leak under the granite.
Overview
Honest, local context — written by working Doon plumbers.
Kitchen plumbing failures don't make headlines like burst pipes — they show up as a soft swell in the underside of plywood, a faint cockroach trail, or a slow drip behind the RO. We treat the kitchen as a 6-line system: cold inlet, hot inlet, sink drain, RO inlet, RO reject and dishwasher line. Every Dehradun kitchen we plumb is laid out with future-proof access — no granite gets broken to change a tap five years from now.
Common Problems
What we typically fix on this service.
Usually a worn P-trap gasket or wrong-bore connector. We swap to a bottle-trap design with serviceable joints.
Route reject into a dedicated 4L collection bottle or extend the line to a kitchen-garden tap. Saves 3L per L purified.
Insulated CPVC hot line + a smaller-bore branch fixes this. No need for a second geyser.
Worn cartridge. Branded brass-body replacement lasts 5+ years in Dehradun's hard water.
Our Process
How a Doon Plumber visit actually runs.
- 1Layout check
Tap location, sink fall, gas-pipe spacing (min. 6 inches clear) and RO accessibility — confirmed in writing.
- 2Branded fittings only
Astral or Ashirvad CPVC, Jaquar/Cera taps, brass-body kitchen mixers — no plastic compromise on hot lines.
- 3Slope & vent
Sink drain set at a 1:50 fall with an anti-siphon vent — no gurgle, no smell.
- 4Pressure & smoke test
8-bar water test on inlets, smoke test on the drain — done before the modular kitchen carcase goes back.

Why this matters
Kitchens fail at the unseen joints. We use only solvent-welded CPVC on hot lines, brass-body mixers (never zinc), and bottle traps with serviceable unions — so a future repair never demands breaking the granite or the back panel.
FAQs
Frequently asked — kitchen plumbing.
Can you install my RO with the existing tap?
Usually yes. We tee off the cold inlet under the sink with an isolating ball valve. Most installs are done in 75–90 minutes.
What's the right gap between water and gas lines?
6 inches minimum, per IS code. We re-route water lines if your existing layout violates this — it's a real safety issue.
Do you do AMC for modular kitchens?
Yes — ₹1,499/year covers sink, RO and tap servicing twice a year plus free washer/cartridge replacements.
