A big problem for anyone who installs a shower in a proerty, over a bath or in a separate cubicle, is making sure that there is sufficient water pressure to operate the shower properly. We all expect a shower to deliver a strong invigorating spray rather than just a trickle of water. So a good way to improve the pressure is to install a boost pump. These pumps can fail from time to time so here is a basic guide to the replacing of a boost for a shower: Firstly, a new replacement pump must be purchased before any work is done to make sure you have the unit to replace the one you are about to remove. It is good practice not to disconnect or remove a piece of equipment unless you have the correct replacement to hand. Willesden Plumbers provide first class knowledge and skills for all plumbing jobs. Make Sure That The electrical supply to the shower is isolated and then isolate the water supply ensuring that it is completely off. The connections can be capped should there be a need to use the water supply in the house. If fitted, open the drain cock to release any water from the pump pipework. If not prepare for a little water discharge as you disconnect the pipework. The connections are usually flexible with push fit or compression joints and the new unit should be the same making reconnection straightforward. Unbolt the old pump from its base and disconnect from its power supply. It is recommended that you use a voltmeter to ensure that no electrical feed is present even though it is isolated. Once disconnected remove the old pump and replace with the new in reverse order of removal. A Willesden Plumber will carry out work that complies with the current Regulations. Plug the new pump into its supply point (usually a socket type outlet). Restore the water supply, operate the pump and check for leaks. NOTE: Where no flexible connections have been provided there will be a requirement to alter the pipework to accommodate this. You must ensure that during this process that a great amount of care must be taken not to damage the plastic water connections on the replacement unit with heat from any soldering procedure that needs to be done. Also do not cross thread the connection.
