SWR pipes - pasting vs washer type

[vpbs_bak]

HI

I asked for a quote from mahesh pipes for PVC (sewage & waste water pipes). They ask back this :

"Kindly go through the above quotation attachment.
Please Note ; Quotation No. 1838 is of SWR Washer type ( Pipe comes in 3 mtrs only )
1844 is of SWR Pasting type ( pipe comes in 6 mtrs only)"

Does anyone know the difference between the two SWR types ? Also, other dealers are saying Supremem pipes are always "Agricultural pipes"(the model numbers start with SP).

Early reply would be very helpful


thanks

Hi,
I suggest you to choose washer type as it can be opened and reworked. Pasting type will be sealed and maintenance will be difficult. Price difference will be little and use door type elbows and T's to make it easier for clearing blocks in future. Pipes come in two types type-A and Type-B. Type-A is sufficient and I am using the same for my project.
Thanks,
