Rated 5 out of 5Â by Rjd2 Premium product, great price.
McAlpine are a premium quality brand, reliable and excellent quality. Price is better than plumbers merchants. Use these Anti siphon traps a lot as they eliminate the classic gurgling noise from draining sinks and also improve the performance of the drainage system, allowing air to enter the system but stopping anything coming back out.

Does exactly what it was designed to do, replacing a different make.

The trap I purchased is not as silent, as McAlpine state it to be. " Silentrap" is their name for this trap
Conventional situation, upstairs bathroom with a drop of 1 meter from trap to the 4" down pipe, over a 3.5 meter run.
Thought I would eliminate the gurgle and installed one of these. The gurgle however was replaced by a deep pulsing noise akin to a motor bike outside followed by a chattering sound from the AAV.
I have tried to contact 'McAlpine Plumbing' but there is no phone number, or email address. There is a 'contact us' form on their website. But that is only available to qualified plumbing professionals! Like you need a degree in plumbing to be able to hand tighten 2 plastic nuts?
So I did as McAlpine instructed and contacted the supplier, Screwfix, who were excellent and offered to supply a replacement trap next day free of charge. You cant really ask for more than that.
When it arrives I will fit it and then look to see if there is anything amiss with the original one, which I hope there is.
I will try to update this post as soon as I've fitted the new one.
