FAQs

Everything you need to know about replacement spare parts, compatibility and next-day delivery.

What spare parts do you stock for sewage treatment systems?

Direct Drainage stocks a wide range of replacement parts and maintenance components for sewage treatment systems, air blowers, pumps and wastewater equipment.

 

Our range includes air blower diaphragms, filters, service kits, replacement fittings, electrical components and other essential spare parts.

 

We supply components for equipment from leading manufacturers, including Klargester, Secoh, Charles Austen, Hiblow and other established wastewater brands.

Product availability varies, so please check the individual listing or contact our team if you need assistance locating a specific component.

How do I find the correct replacement part for my equipment?

Finding the correct replacement part depends on the manufacturer, model and specifications of your existing equipment.

 

We recommend checking the model number, manufacturer part number or identification plate before purchasing.

 

For sewage treatment systems and air blowers, it's particularly important to confirm compatibility, as similar-looking components may not be interchangeable.

We have also added handy filters to help you find the exact part you need!

 

If you're unsure which part you need, contact our team on 01388 537050.

 

You can also email photographs of your existing component or equipment identification plate to sales@direct-drainage.co.uk, and we'll do our best to help identify a suitable replacement.

Are your replacement spare parts genuine manufacturer components?

Our range includes genuine manufacturer spare parts alongside selected compatible replacement components.

 

Genuine components are produced or supplied by the original equipment manufacturer, while compatible alternatives are designed for use with specified equipment.

 

The type of replacement part supplied will be identified in the individual product information wherever applicable.

 

Always check the product description, manufacturer and compatibility details before ordering.

 

If you specifically require a genuine manufacturer component, our team can help confirm availability.

How do I know if a spare part is in stock?

Stock availability is displayed on our product pages wherever this information is available.

 

Products held in our warehouse can usually be dispatched quickly, with next-working-day delivery options available on eligible orders.

 

Some specialist components may be ordered directly from the manufacturer and have longer delivery lead times.

 

If your replacement part is urgent, we recommend contacting our team before ordering to confirm current stock availability and dispatch arrangements.

How much is delivery?

Delivery costs vary depending on the type of product:

 

In-stock Spare Parts: £9.50 - shipped via DPD on a Tracked Next-Day service.
Supplier-shipped Spare Parts: £15 - dispatched directly from the supplier.

 

All delivery charges are calculated accurately at checkout.

What time do I need to order for next-day delivery?

We aim to dispatch in-stock spare parts on the same working day when orders are placed before 3pm, Monday to Friday, excluding public holidays.

 

Next-working-day delivery is available on eligible orders when the appropriate service is selected at checkout.

 

Orders placed after the cut-off time will normally be processed on the following working day.

 

Please note that dispatch and delivery times can occasionally be affected by stock availability, courier delays or other circumstances beyond our control.

Are your prices inclusive of VAT?

It is important to note that all prices listed on our website exclude VAT. VAT will be calculated at checkout. 

I've found the same item somewhere cheaper, can you match the price?

We always aim to offer competitive pricing. If you've found the same item cheaper elsewhere, let us know — we'll do everything we can to match or even beat the price.
