Here's the bit I bodged for speed. I drilled 2 x 20mm holes 1 at either end of the main tube. I knew it at the time but these holes would have been better drilled 19 or even 18mm but I only had a 20mm spade bit so it had to do. If you wanted you could drill the Access Caps to give you an "in line" type. I think this would better but I would have bob hope of getting it in my tank stand.
I then solvent welded the washing machine nozzles in place & clamped for an hour. Overnight would be better. This is just a prototype so will never be used. At this stage it became apparent that time spent aquiring the correct size drill would be time well spent. My nozzles were a bit sloppy and deffo required clamping. If you drilled the correct sized holes you would more than likely not require the clamps.
Just needs some bio balls. I'm not convinced of the integrity of the access caps at the pressure that will be running in there but the guy in the plumbing section at B&Q assured me they were pretty good. I'll hook it up to a powerhead tomorrow & see how we go.
As usual shoot it down folks

Looks good, nice work fella. i would imagine the washing machine nozzles wouldn't weld too well to the ABS pipe tho as the PVC stuff tends not to melt very well? Might be an idea on the next one to solvent weld & silicone as a belts and braces type thing?
