Frequently Asked Questions
Can non-trade customers buy from Plumb Merchants?
Absolutely! We welcome enquiries from both trade & general public - whether you’re on the tools, managing a property or sorting a repair at home, our team will do our best to help.
What information should I bring when looking for a replacement part?
If possible, bring the old part into the shop, or take clear photos from a few angles. Measurements, brand names, pipe sizes and where the part is fitted can all help our team identify the right replacement.
For more guidance, read our guide: How to Get the Right Plumbing Advice.
Can you help me identify a part from a photo?
Yes. Clear photos can help us understand what the part is, where it is fitted and what it connects to. Try to include one wider photo, a few close-ups, any visible markings or brand names, and a measurement if possible.
For more guidance, read our guide: How to Get the Right Plumbing Advice.

Why is my radiator not heating properly?
A radiator may not heat properly for a few reasons, including trapped air, a closed valve, sludge in the system, balancing issues or a problem elsewhere in the heating system.
Check out our tips on How to Bleed a Radiator.
If you’re unsure what part you need, take a photo of the radiator, valves and pipework and we’ll do our best to help.
What’s the difference between a standard radiator and a vertical radiator?
A standard radiator is usually wider and fitted horizontally, while a vertical radiator is taller and slimmer. Vertical radiators are useful where wall space is limited or where you want a more design-led finish, but the correct size and heat output still need to be considered.
Do you stock shower parts and replacement fittings?
Yes, we stock a range of shower parts, fittings and accessories. Availability can depend on the brand and model, so it’s helpful to bring the old part, product details or clear photos when enquiring.
What should I check before replacing a tap?
Check the type of tap, number of tap holes, water pressure, pipe connections and the space available around the sink or basin. If you’re unsure, bring a photo or measurements into the shop and our team will do their best to help you find the solution.
My sink isn't draining properly. What should I do?
Start by removing any visible debris, then try hot water and washing-up liquid or a sink plunger. Avoid mixing drain-cleaning chemicals.
