Black soil pipe uv stability
Just how uv stable is the black soil pipe from screwfix ?
I have a stand pipe set up to the filter . Am thinking of dropping a submersible uv with a float in there ????

My thinking was worse case it fail in a year and its only 10er for the new t that it'll be sat in . Know its not ideal but as I need a new uv am thinking why pay 100 for a used uv that will need plumbing in more restrictions when I can get a submersible new from Burtons 40w for 140 or a 80w for not much more at all . . Not almagram but still

The pipe should last a few years. And as you say it's relatively cheap to replace.
I created a UV guard out of 1.5" waste pipe (cut in half length ways, with a little collar left to go round the amalgam housing) to avoid the seal in my drum being directly exposed to the UV from my amalgam.
It's been going about 2 years and the pipe is still perfectly fine. Although admittedly I don't really need to run my UV that much as the shade from my pergola roof seems to do a good job on its own in preventing algae and blanket weed blooms.

Cheers for the help Lads greatly appreciated . That's the plan then do away with the odd uv units and see what funds are like to if 150 for a 40w or 200 for a 40 almagram
Silly question time what is the difference between normal uv and almagram

Ha ha. I think I did post about it, quite a while ago.
Although your solution looks better, at least your one can bounce some of the UV back out rather than it just getting absorbed into the plastic pipe (if UV works like that).

much higher output at lower temperature, more useable uv wavelength, much longer life, much more expensive

50 quid difference in buying a burtons unit
Then 20 quid more to replace bulb
40w standard £150 bulb 40
40w amalgam £200 bulb 60
That's burtons tho but a lump cheaper than qk not sure if there is much difference in how they work/last

if its an amalgam its an amalgam,
the rest is just brand security?
i've got the DVS amalgam from queni £224 (plus the £11.20 in points you get back)
