Are manifolds just for Underfloor?
Anyone who has installed water based underfloor heating systems has used a manifold; coupled with zone thermostats they give zone-by-zone control over the distribution of heat. But is there a use for manifolds in day-to-day plumbing? Nigel Sanger Technical Manager for JG Speedfit explains why manifold plumbing is increasing in popularity and explores some features and benefits.
Manifold plumbing in this context, is the use of manifolds, plastic or brass for the hot and cold distribution to points of water use, such as sinks, radiators and appliances from a central point. It is also the term used for the central distribution of heating flow and return circuits.
It is this feature of having a single point from which many of the benefits of manifold plumbing originate. One of the biggest benefits of a manifold plumbing system is that it is possible to have no joints in the pipe runs. This removes the need for joints in totally inaccessible places. Fixing small leaks in inaccessible areas can cost the plumber in time, inconvenience, and lost reputation as well as in pound notes.
Unlike conventional systems, manifold plumbing allows the plumber to create a joint free run to the water outlets and appliances. If a fault does occur in the system, or an appliance such as a washing machine or dishwasher develops a fault, with no prior knowledge or expertise the customer can conveniently isolate the problem at the manifold by simply closing off the appropriate marked isolation valve.
By the householder having easy access to isolate each pipe run the inconvenience is drastically reduced and this prevents the installer having to attend an emergency call out at an unsociable hour.
The minimal amount of joints in the system makes maintenance of the system quick and easy. Manifold systems are also easy to extend. This can be especially useful if the customer is looking to add value to the property at a later date by adding an extra bathroom, wet room or cloakroom.
Speedfit Brass Manifolds just screw together in units of 2, 3 or 4 allowing the user to make them as large as is required. The caps are colour coded and have identification built into the heads for all common appliances. Speedfit plastic manifolds can also be joined together and used with a variety of valves.
There are economical benefits to be had by using manifold plumbing, obviously the system lends itself to plastic plumbing which is cheaper than copper and the reduced need for fittings can also realise savings. It may mean only a couple of fittings a job are saved but in the current climate over several jobs you should start to notice the saving.
Are there any disadvantages to manifold plumbing? Well depending on size of installation the manifold could become quite a size and pipe runs can add up. Although with a bit of planning and common sense this can easily be overcome. Overall, the advantages for both installer and end user far outweigh any disadvantages. Manifold Plumbing will become increasingly popular as more installers and end users realise the advantages.
