Thread: Pipe fittings

    Pipe fittings

    Will be starting my filter house pipe work and was wondering what peoples thoughts were on solvent fittings or rubber. Iíve solvent welded all my returns that Iíll never move or be able to get to. But was thinking in the filter house certain pipe connections could be rubber so in future if things change I wonít be cutting pipe and replacing more than I need too.

    I asked the same when I was going mine. Yes use solvent where possible and rubber where it makes sense, i.e. connecting to filter kit.

    Same here. I've got rubber fittings In the filter house. Works fine and makes it so much easier in case any angles are slightly out or if space is really tight.

    rubber fittings can get a bad press,
    but mostly due to the two types being made from two different materials, PVC and EPDM

    the PVC have a habit of splitting the better brands last longer but are still prone to it.

    the EPDM are guaranteed in the chemical industry use for 25 years...
    cost wise the straight couplers are virtually the same price, the bends and reducers though are a lot more expensive.
    Flexseal EPDM Pipe Connectors

    you can get a bit cheaper especially if buying a few from drainage superstore, but need to check the correct product code...

    the ones i bought for my build

    Yes I have used solvent when I can. Put in double Union valves to allow work on sections of the system while still running others. Use rubber connectors where connecting to drum or skimmer and use flexible pressure pipe & / or unions to pumps & ASHPE56601DF-DB6D-4A95-93C2-C8D1E0DDA1C9.jpg

    bet that was fun working those pipe runs out

    how did you connect the to the pump inlet here?
    is that a 3" elbow with a 3" solvent x 2" BSP bush?

    To keep gravity flow to the 2” pump inlet to maximum I used a 4” rubber 90degree to a 3” pressure 90degree with a 2” step down insert to a 2” union ( Yes it was one of the reasons my build has taken so long ) I tried to make sure of redundancy & duplication wherever possible, keep bends to a minimum & pipes & pumps to a maximum (x2. 30,000 vari & x1. 22,000 vari pumps) Yes it cost the earth for fittings but then I want this to be easy at 2am on a cold wet night to re-route the water if there are problems.

    thanks Mike,
    i'm looking to uprate the pumped pipework in my build, to help minimise pipework flow restrictions.

    2" inlet and outlet for the 1.5" 10,000 vario @ 4-5,000 lph. (as it will have a long 6 meter run)
    and 3" inlet and outlet for the 2" 20,000 vario i already have from my old pond but might swap that out for a 30,000 for the vertical 1.5meter lift to the shower.
    though i was hoping they had uprated the inlet and outlet size of the 30,000 to 3" or 2.5" at least...oh well...

    i would love the sheckles to pony up for a flow friend @ £2,000, but at the 18-20,000 lph @1.5 meters i want,
    it would only save me £140 a year in running costs, so over 10 years to make it pay for it's self
