How can I tell which sort of plumbing system I have in my property?
There are generally two types of system installed within domestic properties across the UK - knowing the type you have is an essential first step in selecting the right type of pump or boosting system to improve water pressure and flow.
Gravity Fed System
(Also called a 'Vented System')
A cold water tank (usually located in the roof space)
A ventedhot water cylinder (usually located in an 'airing cupboard' or 'hot-press').
The water pressure available is largely due to gravity and is dependant upon the height of the cold water tank above the appliance being used.The water pressure and flow available from the cold water rising main supply will affect the rate at which the cold water tank refills, but it will have no effect on the water pressure and flow available from any water using appliance (other than for any cold water taps connected directly to the rising main). Water pressure is greatest on the ground floor and reduced on the upper floors.
For a shower on the top floor, the water pressure (static head) may be as little as 0.08 bar!
It is therefore no surprise that this type of system is often referred to as a low pressure system'.
For a Gravity (Vented) 'Low Pressure System' a pump can be installed to increase pressure and flow to an individual shower, the entire bathroom or even the whole house.
Mains Pressure System
Also called an 'Unvented System'
A combination boiler, or
A pressurised (unvented) hot water cylinder.
The water pressure available is largely dependant upon the mains cold water pressure in the supply pipe to the property.
The water pressure will be the best on the ground floor, but the pressure will be reduced on upper floors of the property.
On the third or fourth floor of a multi-storey town house the water pressure may be non existent!
This type of system is often referred to as a 'High Pressure System' - even though the pressure available in many cases may be anything but!
For a Mains (Unvented) 'High Pressure System' a pump, pressure vessels or a combination of both can be installed directly in line with the rising cold water mains supply, boosting water pressure and flow to the entire property, including the combination boiler or pressurised hot water cylinder system.
I need a replacement toilet seat - what info do you need?
We need to know if you would like a standard seat or a soft-close seat - it will help if you can tell us the brand and model or you can email us a picture along with the dimension measurements we need below:
- Measure the distance from the middle of each toilet seat fixture hole.
- Measure the distance from the outer edge to outer edge of the toilet, across the middle of the toilet bowl's hole.
- Measure the distance from the fixture holes to the front of the toilet.
Do I need a 'standard' or 'universal' pump type?
When considering a common application such as boosting the performance of a shower, the pump will need to be able to switch itself on automatically when the shower is switched on.
A key decision in this respect is whether a 'standard' or 'universal' pump type should be used.
Universal Pump Type - If the flow from the shower head is LESS than 1 litre per minute, due to gravity flow without a pump fitted then a 'negative head' situation exists and a 'Universal' pump type must be used.The flow can easily be measured by directing the shower head flow into a measuring jug and recording the fill level after 1 minute.
IMPORTANT NOTE:If there is any doubt at all - especially if the shower has not yet been installed, opt for a 'Universal' pump type.
For a Gravity (Vented) 'Low Pressure System' where the flow from the shower head due to gravity (no pump fitted) is less than 1 litre/min, a 'negative head' situation exists and a 'Universal' pump type must be used.
Standard Pump Type - A 'Standard' peripheral pump allows water to run through its pump heads even when it's not running. The pump has a flow sensor that detects this flow to switch the pump on and boost water pressure and flow. The flow switch needs a flow due to gravity alone of at least 1 litre per minute to activate the pump.If the flow from the shower head is MORE than 1 litre per minute, due to gravity flow without a pump fitted then a 'positive head' situation exists and a 'Standard' pump type can be used.The flow can easily be measured by directing the shower head flow into a measuring jug and recording the fill level after 1 minute.
IMPORTANT NOTE:Just because there is a 'positive head' created by the height of the cold water tank above the shower outlet, there may still not be enough flow to enable a 'Standard' type pump to work!
For a Gravity (Vented) 'Low Pressure System' where the flow from the shower head due to gravity (no pump fitted) is more than 1 litre/min, a 'positive head' situation exists and a 'Standard' pump type can be used.
My tap is constantly dripping, what do I do?
Generally, when a tap drips or lets by, this would usually indicate a blockage between the ceramic discs of the internal cartridge. By performing regular maintenance on your cartridge, this can easily resolve this issue. Details on how to remove the cartridge can be found within the installation/maintenance instructions for your product. Once removed, soak in a descaling solution (or a 50 / 50 mix of warm water and vinegar) for approximately 2 hours, flush under cold running water and replace. Regular maintenance is particularly important if you live in a hard-water area. If this does not work the cartridge will need replacing.
My shower head nozzles have limescale, what do I do?
Due to the majority of the UK being built upon chalk, unfortunately, limescale is a common issue. When limescale builds up around the nozzles of a showerhead, this can create blockages/misdirection of water flow. To remove the limescale, and restore your showerhead to full functionality once more, we have limescale removers in stock, and gently clean the limescale from the nozzles of the showerhead. Once removed, clean all over with warm soapy water with a soft cloth.
If you don't have a water softener installed, we highly recommend you do as this will come with many benefits such as softer water. It will defintaley make your applicances last longer.
