Low Water Pressure Diagnosis and Repair

Weak showers and slow-filling tubs usually have a clear cause. We test the pressure and flow, find the real problem and fix it, whether that is a valve, a corroded pipe or a service line that is simply too small.

Are you tired of showers that barely run or waiting forever for the tub to fill? Low water pressure is one of the most common complaints we hear from owners of older homes. The good news is that it almost always has a clear cause, and once that cause is fixed, the difference is immediate.

We offer low water pressure diagnosis and repair for homes across Toronto, Peel and Halton. Our team tests the system, explains what is holding the water back and gives you a written estimate for the fix.

Common causes of low pressure

There are several things to consider. Galvanized steel pipes were common in older homes, and they corrode from the inside until only a narrow opening is left. Many older services are also only 1/2 inch, which cannot keep up with a modern household. Other causes include a main shutoff that was never fully reopened, a failing pressure regulator and hidden leaks.

Testing before we recommend anything

We start by measuring pressure and flow at the meter and at a few fixtures. That tells us whether the problem is coming in from the street or developing inside the house. You will not be sold a new water line if a valve or a short section of pipe is the real issue.

Fixing the problem for good

Depending on what we find, the fix may be as simple as replacing a valve or regulator, or as involved as replacing galvanized piping or the service line itself. If the service is undersized, lead or galvanized, a trenchless replacement is usually the most cost-effective long-term solution.

Enjoy steady pressure again

If low pressure is making daily life harder, reach out to our team. We will find the cause, explain your options in plain language and put the price in writing before any work begins.

Know the signs

Signs of a pressure problem

  • Weak flow at every tap, not just one fixture
  • Pressure that drops badly when two fixtures run at once
  • Showers upstairs that are much weaker than in the basement
  • Brown or rusty water along with low flow
  • Pressure that has slowly got worse over the years

Our approach

How we fix low water pressure

Pressure and flow testing

We measure static pressure and flow at the meter and at your fixtures to see where the loss is happening.

Check valves and regulators

A main shutoff that is partly closed or a failing pressure regulator can cause the whole problem, and they are simple to correct.

Look at the piping

Galvanized steel narrows from the inside as it corrodes. We check for it and replace sections that are restricting flow.

Upgrade the service when needed

If the service line from the street is too small or is lead or galvanized, we recommend and install a correctly sized replacement.

Pricing

What affects the cost of low water pressure

Every property is different, so we quote after we inspect. These are the factors that move the price up or down.

  • Whether the cause is a valve, a regulator, interior piping or the service line
  • How much galvanized or undersized pipe is in the home
  • Access through finished ceilings and walls
  • Whether the service line needs to be replaced or upsized
  • Fixture count and any planned additions

Written quotes you can compare

Our estimates list materials, labour, permits and restoration on separate lines, so you can see exactly where your money goes and compare quotes fairly.

Our process

How we work

Every job follows the same six steps, so you always know what happens next and what it costs.

  1. Camera first

    We look inside the pipe or trace the line before anyone talks price, so the quote is based on what is really there.

  2. Written quote

    You get an itemized estimate in writing, with the rebates that apply and your cost after them.

  3. Permits booked

    We pull the plumbing or building permit and book the inspections with your municipality.

  4. Low-dig work

    Where the ground allows, we use trenchless methods to replace pipe through small access pits.

  5. Restoration

    We backfill, compact and tidy the site. Any concrete, sod or finish restoration is listed line by line in your quote.

  6. Rebate filing

    We prepare the invoices, photos and permit proof your rebate application needs.

FAQ

Low Water Pressure questions

Straight answers to the questions homeowners ask us most. If yours is not here, give us a call.

Why is my water pressure low in an older house?

The most common causes are corroded galvanized pipes, an undersized or lead service line, a partly closed main valve or a failing pressure regulator. A simple test usually narrows it down quickly.

Can a new water service fix low pressure?

If the service line is the bottleneck, yes. If the problem is inside the home, the service alone will not solve it, which is why we test before recommending anything.

Is low water pressure a sign of a leak?

It can be. A leak on the service line or inside the walls can reduce pressure, so we check the meter for movement as part of every visit.

Should I install a booster pump?

A booster pump can help in some buildings, but it does not fix a corroded or undersized line. We recommend it only when the piping is sound and the supply pressure itself is low.
