Filter Plumbing

[Big Frank]

I have a multi bay filter with 2 loose pipes, one seems to fit into the outlets at the bottom and has a gate valve on, is this for just releasing the waste, if so how often should i do it. Also I have another pipe and gate valve is that for the inlet to the multi bat filter? Am I correct in, pump to UV to gate valve to inlet on multi bay?

Fin the images is my current pond its been home to my 2 ghost koi and 2 goldfish for 10 years, the big black pond is the new pond that is going to take its place. Its 1200 gallons and will need a bigger filter etc. the other pictures are the mix of bits and bobs I got with the new pond as a job-lot

Hi there. You should do a 20% water change each week. Which means you would use that waste port to get rid of the old water and put in fresh water and deschlorinator to replenish. Nice system! the UK is way ahead of us in pond filtration!

thanks all makes perfect sense now, I still have another gate valve, would it be on the in-flow. If so what for

I'm guessing you should have one gate-valve on the in-flow and another on the outflow. This way you can service the filter without having to shut everything down.

You would shut your inflow valve first and your outflow one second. If you do it in reverse, your filter will overflow since you have water coming in, but not going out.

Hope that makes sense.

yes making sense, but shut the pomp 1st right before shuting the vavle on the inflow

I think they did this so you wouldn't have to shut the pump down. The pump would still figure there was water in the line, I'm assuming is what the person was thinking.
