Frequently Asked Questions
Do I need any extra fittings to install this valve?
Do I need any extra fittings to install this valve?
No. It's a solvent weld fitting, so it bonds directly onto pipework without needing separate adaptors.
Can I remove my pump without draining the whole pond if I fit this valve?
Can I remove my pump without draining the whole pond if I fit this valve?
Yes, that's the main purpose of a slide valve: it lets you shut off flow to a section of pipe so equipment downstream can be removed or serviced without draining the whole system. You'll also need a demountable union to physically disconnect the pump itself.
Is a demountable union included with this valve?
Is a demountable union included with this valve?
No. Only the valve itself is supplied. A demountable union is a separate item you'd need to fit alongside it if you want to disconnect a pump completely, rather than just shut off its flow.
This solvent weld slide valve allows you to isolate a section of pond pipework and shut off the water flow, helping you lift out pumps or other equipment for maintenance without draining the whole system. It suits anyone plumbing in a pond pump that needs a dedicated shut-off point on its inlet or outlet. Because it solvent welds straight onto pipework, there's no separate adaptor needed to get it fitted.
Overview A slide valve, also called a gate valve, is a pipework fitting used to control or fully shut off water flow. This one is a solvent weld type, so it bonds straight onto pipe with solvent cement rather than relying on separate adaptors or seals.
That makes it useful for pond keepers who need to isolate a pump or other in-line equipment: it lets you stop flow to one section of pipework and work on it without draining the whole pond. Fitting one on the inlet and outlet side of a pump helps you avoid emptying the system just to carry out routine maintenance or swap out a faulty part.
What you get is the valve itself, ready to solvent weld into new or existing pipework. It's worth noting that a slide valve on its own won't let you fully disconnect a pump: you'll also want a demountable union so the pipework can be physically separated, and that union is a separate item, not included here.
Key benefits Because it solvent welds directly onto pipe, you're not relying on a separate adaptor or push-fit fitting to get a secure joint, which is one less part to source and fit. Using one on the inlet and outlet of a pump follows the setup generally recommended for pump installations, giving you a shut-off point on both sides of the equipment you're most likely to need to service.
