You want to push your grey waste pipe onto one of these spigots, but make sure you have a jubilee clip on the hose first, this should be nice and loose and just floating for the time being. If yours look like the image above with the “ribs” on them then this means they can be cut down to accommodate different hose widths. You probably don’t need to bother with this however and should just leave it as is. If the hassle of installing a proper standpipe is just too much or you don’t have the funds to pay for a tradesman to do it for you the other option is to replace the existing waste outlet under your sink with a new one featuring an appliance nozzle. this is one situation that pops up frequently, what do you do if you have both a dishwasher and washing machine trying to connect up to a single spigot? Well, I talk about this in more detail here, but I will add the TL;DR below! Inside the property, use an SDS drill and a long drill bit to drill through the wall in the position that you will install the waste and where it will exit the property. Ensure it is high enough so that once the pipe runs through you get the required minimum of 1:40 drop to ensure correct drainage.

As we have mentioned, installing a standpipe to use as an appliance waste is the best solution and can be done fairly easily, as long as you have good access. Once the waste hose is connected you can tighten up the jubilee clip to make the hose really secure. Jubilee Clip On Washing Machine Waste Pipe This is due to the fact that any new pipework that will need to be installed for any wastes can be kept to a minimum, especially if using a combined sink and appliance waste trap as the appliance waste hose is only a set length. Finally use a good quality external silicone sealant to fully fill the gaps around the pipe running through the wall to stop any heat loss.Washing machines and dishwashers, once installed, must deliver their waste water to the foul drainage system for your home. This is the same system which takes the toilet and basin waste. It is illegal to put this waste water into your surface water system which is the water collected by your gutters. One final important point is that the length of waste pipe for both washing machines and dishwashers should not exceed 3 metres in length. This includes the waste hose running from the machine. Do You Have to Install a Waste Trap? Most washing machine waste hoses usually come with a pre set bend which takes the hose into the top of the stand pipe about 200mm. I have illustrated an image below for you to make it easier to see what they are. Spigots on a waste trap

Place a joiner on the end of the existing pipe and glue it in place. Add any further pipe joints to remake any waste outlets that you cut away e.g. sink waste etc.When the washing machine is working it pumps the wastewater out and is more than capable of pumping it uphill, so don’t worry about that.

In terms of the height, the top of the standpipe should be 100mm under the underside of the worktop. If there is no worktop then the top of the waste pipe should finish at approximately 50mm down from the top of the washing machine or dishwasher. In some instances, running a new waste pipe from an existing waste isn’t going to be possible or there may be a convenient drain or soil pipe just the other side of the wall that would be much easier to run a waste to rather than removing kitchen units or trying to alter them. Once in place, tighten the Jubilee Clip all the way to hold the pipe in place. Once this is done, you’re all finished. Once all prepared, slip the pipe through the wall and mark the pipe clip fixings and then fix them in place using screws and wall plugs. If you have a rotatable spigot then you can move this into an upward position to help with that. You may well have a fixed spigot as I do. If this is indeed what you have under your sink then you will need to move the pipe into a position where it feeds down into the spigot at some point.

Tools and Materials Needed for Installing a Waste Trap

As the cupboards under kitchen sinks are notorious for storing items that don’t fit anywhere else the first job is to clear some space to work in. along with 3 projects on the different types of waste pipes you can get to do the job an how they can be joined:

Which ever machine waste trap you are going to install you will need a number of tools and products to get the job done correctly. Due to the nature of the areas in which sinks tend to exist, waste traps can over time fill up with all sorts of unmentionable substances. Once in place and you have connected up the water supply and plugged it in, turn the machine on and run a test to make sure all is well and working. So, in answer to the question of; do you have to install a waste trap? The answer is a definite yes! Tools and Materials Needed for Installing a Waste TrapTo find out more about how waste traps work, see our project here. Types of Waste Trap for Washing Machines and Dishwashers You want the waste pipe to run uphill after coming out of the spigot if possible. What this does is stops any waste from the sink from coming down the pipe and into your washing machine. In terms of the waste trap itself the document states that it should be at minimum 40mm in diameter and the depth water in the trap to form an effective seal should be at least 75mm. Next, using a tape measure, measure from the new pipe joint over to where the new standpipe will be positioned and cut a piece of UPVC pipe to length, remembering to measure from inside the collar of the joint where the pipe will butt up to. Tidy up the end with a piece of sandpaper.
