Product description
What PPR pipe diameter should be installed? Calculate it in one minute.
You are a plumber. You know: after the meter, a 20 mm PPR pipe is typically used. But if there are two bathrooms, three, or high-powered equipment, a 20 mm pipe may not be enough. And manual calculations are time-consuming and tedious.
This calculator solves the problem. Enter the fixtures and get a ready-made answer: which diameter to install.
What it calculates:
Total flow rate (L/min, m³/h)
Recommended PPR pipe diameter (20, 25, 32, 40 mm)
Explanation of what this diameter means
Why it is convenient:
Simple. Enter the number of fixtures and get an answer.
Practical. Logic aligned with real-life usage: up to 20 L/min → 20 mm pipe, up to 35 L/min → 25 mm pipe, up to 60 L/min → 32 mm pipe.
Fast. Calculations done in one minute instead of manual estimations.
Protected. Formulas are hidden, so buyers cannot tamper with them.
What’s included:
Excel calculator (auto-calculates).
Instruction on how to use it.
Who is it for:
Plumbers — to select the correct diameter on-site.
Handymen — for quick checks.
Anyone doing renovations — to understand what the crew is doing.
Important: Flow rates in the table are averages according to SP 30.13330. Pressure is measured via a gauge. If there is no water flow, this will be obvious immediately — such cases are beyond the scope of this calculation.
