Common Questions

Frequently Asked Questions

The questions we hear most often from Cardiff homeowners. If you don't see yours here, just give us a call.

If you see water leaking, follow the drips and turn off the nearest shutoff valve. Place a paper towel or newspaper underneath — if a drip falls it'll leave a mark. Check any supply lines or appliances nearby for splits, breaks or unattached hoses. Once you've found the source you can try to fix it, or give us a call and let us know what you've found.
This is one of the most common problems we see. Most of the time it's old grout or a bad pan under the shower. We start by checking whether the leak is constant or periodic — constant usually means a pressurised line; periodic usually means grout, sealant or the pan. There are a series of tests we run to track it down properly, including filling the bath halfway, blocking the drain on showers, and capping the shower arm. If it turns out to be water bleeding through old grout, that's an easy fix.
Is the top of the toilet flange level with the finished floor? If it's too low, use two wax rings — one regular on the bottom and one with a plastic horn insert on top. Leaks can also happen if a glued flange wasn't bonded properly. Sometimes the toilet just needs to be slightly repositioned if the floor is uneven. We can sort all of this out for you on a quick callout.
It depends on the age and type of your water heater. Electric heaters usually have two elements — one on top, one on bottom. If the bottom one stops working, only the top of the tank heats up. If the top one goes, you'll get no hot water at all. There's also a reset button that can trip — if it has, that's a sign something is wrong. Give us a call and we'll diagnose it properly.
This is usually caused by a non-pressure-balanced shower valve, common in older homes. The fix is to install a pressure-balanced shower valve — newer homes have these as standard. It's a straightforward upgrade that makes a big difference to comfort.
There are several possible causes. There may not be enough water moving from tank to bowl, the fill valve may need adjusting, or the siphon jets under the rim could be clogged with hard water deposits. Occasionally there's an object stuck inside the bowl. We can quickly diagnose it and fix it for you.
Yes — we offer rapid emergency response for plumbing issues right across Cardiff and South Wales. Burst pipes, major leaks, blocked drains or anything else that can't wait — call 07463 977090 and we'll get to you as fast as possible.
