Going Away This Summer? Don’t Forget These Essential Plumbing Checks Before You Leave
If you are planning a summer holiday this June, your to-do list is probably already full of packing, booking confirmations, and making sure the house is secure. One thing many homeowners forget, however, is their plumbing.
Leaving a property unattended for several days or even a couple of weeks can turn a small plumbing issue into a much bigger problem. A slow leak, a faulty valve, or an unexpected boiler issue can cause damage while nobody is home to spot it. Taking a few simple precautions before you leave can help protect your property and give you extra peace of mind.
At Holt Plumbing and Heating, we often help UK homeowners prevent avoidable summer plumbing problems with a few sensible checks before travel.
Why summer holiday plumbing checks matter.

During the colder months, people tend to think more about heating and boiler breakdowns. But summer can bring its own plumbing concerns, especially when a house is empty.
If a pipe starts leaking while you are away, even a minor drip can damage flooring, ceilings, cabinets, or walls over time. Stagnant water, blocked drains, and unnoticed faults can also become more serious if they are left unchecked.
A quick plumbing check before your holiday is one of the simplest ways to reduce the risk of coming home to an unpleasant surprise.
Your pre-holiday plumbing checklist.

Before heading off, it is worth giving your home’s plumbing and heating system a once-over.
1. Turn off the water supply if possible.
If your property is going to be empty for more than a few days, turning off the mains water supply is often a smart precaution. This can greatly reduce the risk of leaks causing serious damage while you are away.
If you are unsure where your stopcock is or whether it is working properly, it is best to check this well before your departure date.
2. Check for hidden leaks.
Walk around your home and look for common warning signs of plumbing leaks, including:
- Damp patches under sinks
- Water marks on ceilings or walls
- Dripping taps
- Slow-filling toilet cisterns
- Unusual smells near pipework or drains
Even a small leak can worsen when left unattended. If anything looks suspicious, it is worth arranging a professional plumbing inspection before you travel.
3. Clear sinks, showers, and external drains.
Blocked or slow drains can become worse over time, especially if debris is already building up. Before you leave, make sure sinks, showers, and baths are draining properly.
It is also a good idea to check outdoor gullies and drains, particularly after windy or wet weather. Leaves, dirt, and garden debris can quickly cause blockages.
4. Set your boiler appropriately.
In June, your heating system may not be in regular use, but your boiler may still be providing hot water. If you are going away, check the settings carefully.
Many modern boilers have holiday mode or timer controls that can help reduce unnecessary usage while keeping the system protected. If you are unsure how to adjust your boiler settings safely, professional advice is always recommended.
Don’t overlook bathrooms and kitchens.

Bathrooms and kitchens are the most common areas for hidden plumbing issues. Before leaving, take a moment to inspect:
- Toilet bases for any signs of seepage
- Flexible tap connectors under sinks
- Appliance hoses on washing machines and dishwashers
- Sealant around baths, showers, and sinks
A worn hose or loose connection can fail without warning. Catching the problem early is much better than discovering water damage when you return.
Simple steps for extra peace of mind.

A few extra measures can make all the difference when your home is empty.
Ask someone to check in.
If possible, ask a trusted friend, neighbour, or family member to pop in while you are away. They can quickly spot obvious plumbing or heating issues before they become serious.
Test your stopcock in advance.
Do not leave this until the day you travel. If the valve is stiff, stuck, or leaking, it may need attention from a qualified plumber.
Book any repairs early.
June can be a busy time for household maintenance, and waiting until the last minute is rarely ideal. If you have noticed small issues around your home, sorting them now can help you avoid stress later.
Leave home with confidence this summer.
Going away should be relaxing, not a cause for worry about what might be happening back at home. A few straightforward plumbing and heating checks can help protect your property, reduce the risk of leaks, and make sure everything is in good order before you lock the door.
