A dependable water system makes everyday use of a campervan or motorhome much easier.
WeConvert installs, upgrades and repairs campervan and motorhome water systems from our private workshop in Blackburn.
Whether you need a simple sink and cold-water supply, an underslung fresh-water tank, a complete hot-water and shower system or help tracing an existing leak, we can design the installation around your vehicle and how you intend to use it.
We work with customers across Blackburn, Darwen, Accrington, Burnley, Rossendale, Bolton, Chorley, Preston and the wider Lancashire and North West area.

We can install a complete new system or improve an existing setup in stages.
Complete Campervan Water Systems
The right water system depends on how the vehicle will be used.
A weekend camper may only need a compact fresh-water supply and sink. A larger campervan or motorhome used off-grid may require greater tank capacity, a pressurised pump, hot water and a shower.
Before recommending a system, we consider:
- Number of people using the vehicle
- Typical trip length
- Whether you use campsites or travel off-grid
- Whether a shower is required
- Whether hot water is needed
- Available space inside and beneath the vehicle
- Vehicle payload
- Winter use
- Existing furniture and equipment
- Access for filling, draining and future maintenance
A complete system may include:
- Fresh-water storage
- Waste-water storage
- External filler
- Water pump
- Sink and tap
- Shower supply
- Hot-water appliance
- Drain valves
- Tank-level display
- Suitable pipework
- Electrical supply for the pump
- Testing and handover
The aim is to create a system that is practical, reliable and easy to maintain.
Fresh-Water Tank Installation
Fresh water can be stored inside the vehicle or in a suitable underslung tank.
Internal water tanks
An internal tank may be fitted beneath a bed, inside a seat base, within a rear garage or inside suitable furniture.
Internal tanks are generally better protected from road damage and freezing, but they take up valuable storage space.
They must also remain accessible for inspection, cleaning and maintenance.
Underslung water tanks
An underslung tank preserves more interior storage by using space beneath the vehicle.
This can be a good option where:
- A suitable tank is available
- Ground clearance can be maintained
- Secure mounting points are possible
- Filler and pump connections can be routed sensibly
- The tank can be protected from heat and road debris
- Winter use has been considered
We inspect the underside of the vehicle before confirming that an underslung installation is suitable.
Underslung Fresh and Waste Tanks
We can install suitable fresh- and waste-water tanks beneath many popular panel vans and campervans.
The work may include:
- Tank supply
- Secure brackets or retaining straps
- Fresh-water inlet
- Outlet connection
- Breather
- External filler
- Drain valve
- Waste-water inlet
- Pump connection
- Level sensor
- Pipework supports
- Suitable protection where required
Tank capacity must be balanced against payload and available space.
Water is heavy. A 100-litre tank carries approximately 100 kilograms of water before the tank and fittings are included.
The largest tank that physically fits is not always the best choice.
Waste-Water Systems
A waste-water tank collects water from sinks, showers and other suitable outlets.
This allows the water to be disposed of at an appropriate location rather than discharged directly beneath the vehicle.
A waste-water installation can include:
- Underslung waste tank
- Sink connection
- Shower connection
- Large-bore waste pipe
- Tank breather
- Drain valve
- Level monitoring
- Access for cleaning
Waste pipework needs suitable fall and should avoid unnecessary bends or restrictions.
Poorly routed waste systems can drain slowly, retain water or develop unpleasant smells.
We plan the tank and pipework around the available space beneath the vehicle.
Campervan Water Pumps
The pump supplies water from the tank to the taps, shower and compatible water heater.
Depending on the system, we may install:
- Submersible pumps
- External pressure pumps
- Filters or strainers
- Accumulator tanks
- Pump switches
- Suitable electrical protection
- Accessible isolation
The pump must be compatible with the taps, pipework and water-heating equipment.
A pump that is too powerful can cause excessive noise, leaks or pressure problems. A pump that is too small may provide poor flow.
We size the pump around the complete system rather than choosing it by maximum flow rate alone.
Sinks and Taps
We install and replace suitable campervan and motorhome sinks and taps.
Options may include:
- Compact stainless-steel sinks
- Combination sink and hob units
- Folding taps
- Mixer taps
- Cold-water taps
- Hot and cold taps
- Pressurised-system taps
- Microswitch taps
- Removable kitchen-pod sinks
The installation may involve:
- Worktop preparation
- Sink and tap fitting
- Fresh-water connection
- Waste connection
- Sealing
- Pump wiring
- Access below the sink
The tap must be compatible with the pump and water system being used.
Where gas or electrical equipment is nearby, this must be considered before the furniture or worktop is altered.
Campervan Shower Installation
A campervan shower requires careful planning around water capacity, drainage, ventilation and hot-water supply.
A shower installation may include:
- Hot and cold water
- Shower mixer
- Shower head
- Shower tray
- Waste connection
- Waterproof internal finishes
- Roof ventilation
- Suitable pump
- Hot-water system
- Fresh- and waste-water storage
Before recommending an internal shower, we consider:
- Available washroom space
- Fresh-water capacity
- Waste-water capacity
- Hot-water recovery
- Pump flow
- Ventilation
- Vehicle payload
- How frequently the shower will realistically be used
For smaller campervans, an external shower point may be a more practical and space-efficient option.
External Shower Points
An external shower connection can be useful for:
- Rinsing muddy equipment
- Washing pets
- Cleaning bikes
- Outdoor showering
- Washing boots
- General campsite cleaning
The outlet can provide cold water or hot and cold water where the system allows.
Its position needs to be accessible while remaining protected from damage and weather exposure.
Campervan Hot-Water Systems
Hot water can be provided using several types of appliance.
Possible options include:
- Truma Combi systems
- LPG water heaters
- Diesel-powered combined systems
- Electric water heaters
- Calorifiers
- Other suitable leisure-vehicle appliances
The best option depends on:
- Available installation space
- Existing LPG supply
- Electrical capacity
- Off-grid requirements
- Shower use
- Water-storage capacity
- Existing heating equipment
- Desired heating time
Where an LPG appliance is used, LPG pipework, appliance connection, testing and commissioning are completed by our competent leisure-vehicle LPG subcontractor.
We coordinate the plumbing, electrical, furniture and specialist gas work as part of the complete installation.
Water-System Repairs
We can investigate and repair many common campervan and motorhome plumbing problems.
These may include:
- Water pump not running
- Pump running continuously
- Poor water pressure
- Intermittent water flow
- Leaking taps
- Damaged pipework
- Loose fittings
- Tank connections leaking
- External filler problems
- Slow waste drainage
- Shower tray not emptying
- Water-heater connection leaks
- Frost damage
- Inaccurate tank-level readings
- Existing DIY systems requiring correction
Where the cause is not obvious, we may begin with a chargeable diagnostic assessment.
We will explain what we have found before undertaking significant additional work.
Campervan Water Leaks
Even a small leak can damage furniture, flooring, insulation and electrical equipment.
Common leak points include:
- Tap connections
- Pump fittings
- Tank outlets
- Water-heater connections
- Pipe joints
- Fill pipes
- Drain valves
- Shower mixers
- Sink wastes
The visible water may not appear directly beneath the failed connection.
Access panels or sections of furniture may need to be removed to locate the source.
Where water has already damaged the surrounding interior, additional repair work may be required after the leak has been resolved.
Winter Use and Frost Protection
Campervan water systems can be vulnerable to freezing.
Water expands when frozen and can damage:
- Tanks
- Pumps
- Taps
- Pipework
- Filters
- Water heaters
- Drain valves
A system intended for colder conditions may need:
- Protected tank location
- Insulated pipework
- Heated tank provisions
- Accessible drain points
- Frost-protection valves
- Pipe routing away from exposed areas
No system is completely immune to freezing.
Where the vehicle is stored unused during cold weather, draining the water system may still be necessary.
We aim to design systems that can be drained and winterised without unnecessary dismantling.
Modifying Existing Water Systems
We can alter suitable existing campervan and motorhome water systems.
This may include:
- Adding a larger tank
- Moving from an internal to an underslung tank
- Adding a waste tank
- Replacing a pump
- Adding hot water
- Adding an internal or external shower
- Moving a sink
- Improving drainage
- Replacing damaged pipework
- Adding tank-level monitoring
- Improving access to service components
- Correcting unsuitable previous work
Before altering the system, we need to understand how the existing plumbing, electrics and appliances are connected.
Concealed areas may need to be opened before the full scope can be confirmed.
Water Systems for Self-Build Campervans
We can complete the water and plumbing stage of a self-build campervan project.
This can suit customers who are building the furniture and finishes themselves but want the tanks, pumps and plumbing installed professionally.
The water system should ideally be planned before:
- The floor is permanently installed
- Furniture is fixed in place
- Wall panels are closed
- The shower room is completed
- Electrical equipment occupies potential service areas
Early planning allows suitable routes to be reserved for fresh water, waste water, hot water, tank fillers and drains.
Customers completing later work themselves should avoid drilling or fixing into concealed plumbing routes.
Motorhome Water-System Repairs and Upgrades
We can undertake selected water-system repairs and upgrades in factory-built and coachbuilt motorhomes.
Suitable work may include:
- Pump replacement
- Tap replacement
- Pipework repairs
- Tank fittings
- External fillers
- Shower plumbing
- Water-heater connections
- Drain valves
- Waste-system alterations
- Tank-level sensors
- Leak diagnosis
Motorhomes often use manufacturer-specific fittings and concealed pipe routes.
The feasibility of a repair depends on access, component availability and the extent of any damage.
Major damp reconstruction or structural motorhome body repairs are outside our normal scope.
