Home / Services / Hydronic Cleaning & Flushing
Pipe diameter determines the flow required to flush a hydronic circuit. Cleansol plans, executes and measures flow through each branch, with documented results against the project flow targets.
The Buyer Problem
A large chilled water system can have small-diameter branches that require a much higher flow velocity to flush than the main loop. Planning a hydronic flush without branch-by-branch flow targets means some circuits are inadequately flushed while others are over-flushed.
Flow targets come from the project requirements, not from a universal rule. Cleansol plans the flushing sequence, measures actual flow through each branch and records the results against the specified targets.
Systems Covered
When It Is Required
Live Flow Verification
Cleansol measures and records actual flow through each branch in scope. Results are recorded against the project target and included in the turnover package.
Example only. Actual measured values from a representative project. Branch and target designations are not client-specific.
Cleansol Scope of Work
Cleansol reviews the system drawings and develops a branch-by-branch flow plan with the required flow rates for each circuit derived from the pipe diameters and the project specification.
Flushing pumps, strainers, temporary piping and flow measurement equipment are staged and connected. Isolation and temporary bypasses are coordinated with the site team.
Each branch is flushed in sequence, with filtration in the flushing loop to remove debris. Strainer baskets are inspected and documented through the process.
Actual flow through each branch is measured and recorded against the project target. Branches that do not meet target are investigated and re-flushed.
System water quality is verified against the acceptance criteria in the project documents. Chemical treatment is applied only if specified and approved.
The branch flow log, strainer inspection records and water quality results are assembled into the CLEANDOC package for the turnover package.
Flow Targets Come From the Project, Not a Universal Rule
Cleansol does not publish a universal velocity target because the right target depends on the project specification and the system design. We use what the project documents specify or, in the absence of a specification, work with the engineer to establish appropriate criteria.
Scope Alignment
Flow plan, temporary equipment, flush execution, flow measurement, water quality testing in scope and documentation.
System access, utilities, acceptance criteria, water treatment specification if applicable and the approved waste disposal path.
Flow targets per circuit, specification and resolution of design questions raised during constructability review.
Temporary connection points, isolation, strainer installation and system readiness at the agreed schedule milestones.
Equipment and Temporary Systems
Cleansol configures portable flushing pumps, temporary bypass piping, strainers and portable flow measurement instrumentation for each flushing circuit. Equipment is staged and connected to minimize interference with other active construction scopes.
Verification and Acceptance
Every branch in scope is measured individually. The branch flow log records the measured value and the project target for each circuit, and any branch that does not meet target is flagged and re-evaluated. The complete log is included in the turnover package.
Turnover Deliverables
Measured flow vs. project target for each branch in scope.
