The disadvantage is that in order to clean them, the section of pipe has to be removed. This is the reason why they are usually used temporarily until a permanent strainer, such as a basket or tee strainer can be built. In recent days however, they can be left there as long as the pipe does not get choked up. 

In case a replacement of existing strainers are required, we can also fabricate the strainer according to any customized design requested by customer. Contact us to have a specialist advise you to ensure the right replacements will be supplied.
