The Cistern in the Loft — Fault Diagnosis on Cold Water Systems, 9289 Phase 3 Unit 311

So why do we maintain cold water? Before we get into the faults, let's talk about maintenance, because these two are joined at the hip.

Most faults you'll ever diagnose are really just maintenance that didn't happen or happened too late.

Here's the fact that might surprise you.

Water supplies comes into domestic dwellings after consistently monitored for quality by the water company.

So that side of things shouldn't be an issue and you don't need to worry about.

General maintenance of water quality within the property itself isn't usually a requirement either.

But there are two tests that generally do matter and you'll carry them out before any installation work on a cold water system.

A flow test using a flow cup, sometimes called a wear cup, and a pressure test using a pressure gauge.

Both exist to confirm the same basic thing, that there's significant water at the correct pressure once you've finished a job.

Now, once that system is installed and running, whose job is it to look after it? the homeowner they're responsible for the part work and components within their property and plenty of them components need regular attention to keep working properly so why bother maintaining cold water systems at all if the water quality is already being handled upstream a few solid reasons you maintain it to allow maximum performance at the system to prevent corrosion build up in the pipe working components and to prevent the growth of bacteria and legionella is the one that gets named specifically because the stagnant water or poorly maintained cold water system sitting at the wrong temperature with low turnover is exactly the kind of environment it thrives in You maintain it to keep components operating at their design specification, to identify potential problems before they become emergencies, and simply to ensure the system works effectively.

Think about this from the customer's side for a second.

Nobody rings a plumber because they fancy a chat about their assistant.

They ring because something's already gone wrong, and usually it's gone wrong at the worst possible time, Friday evening, bank holiday weekend, the day before they're hosting family.

Every one of these reasons for maintaining an assistant properly is really just a way of avoiding that phone call in the first place.

Word knowing too, this responsibility doesn't just apply to a three-bed semi.

Routine maintenance is required in both dwellings and commercial buildings.

Though in commercial premises, more of the responsibility gets pinned on what's called a reasonable person.

We'll come back to that idea properly in later episodes.

But keep it far away.

It's not just a domestic conversation.
